Regenerative medicine

Regenerative medicine encompasses a broad range of approaches aimed at repairing, replacing, or regenerating damaged or diseased tissues and organs in the body. It draws upon principles from biology, engineering, and other scientific disciplines to restore both the structure and function of compromised tissues and organs. The concept underlying regenerative medicine involves utilizing the body's innate healing mechanisms to facilitate tissue repair and regeneration. This incorporates various techniques used either independently or together, and include stem cell therapy, tissue engineering, electro-stimulation, gene therapy, organ regeneration, 3D bioprinting, and nanotechnology, which either stimulate the body's natural regenerative processes or provide external support for tissue regeneration.
 
Brief history

Regenerative medicine has a rich history, driven by humanity's quest to heal and restore damaged tissues and organs. From ancient civilizations to modern times, medical science has continually evolved, seeking solutions to overcome the limitations of conventional treatments. This pursuit has given rise to the field of regenerative medicine. Early healers in ancient civilizations explored various remedies and techniques to promote tissue repair, ranging from herbal medicines to primitive surgical interventions. These practices laid the groundwork for our understanding of the body's inherent regenerative capacity.
 
In the 20th century, scientific advancements began unlocking new possibilities. The discovery of stem cells in the 1960s marked a breakthrough, revealing a versatile cell population capable of self-renewal and differentiation into specialized cell types. This discovery represented a paradigm shift in medical research and served as the foundation for modern regenerative medicine. The isolation and cultivation of human embryonic stem cells in the early 2000s was a significant milestone, offering potential for regenerative therapies. However, ethical concerns surrounding their use prompted scientists to search for alternative approaches. This led to the discovery of induced pluripotent stem cells (iPSCs) in 2006, which could be derived from adult cells and reprogrammed to resemble embryonic stem cells, thus bypassing the ethical concerns.
 
In recent years, regenerative medicine has experienced a surge of new and rapidly evolving medical technologies. Tissue engineering, biomaterials, gene editing techniques [a method for making specific changes to the DNA of a cell or organism], and advanced imaging modalities have impacted the field, enabling the creation of 3D tissue constructs, the bioengineering of organs, and direct tissue regeneration within the body. Regenerative medicine has expanded beyond traditional approaches, encompassing a wide range of therapeutic strategies, including cell-based therapies, gene therapies, electro-stimulation, and the utilization of growth factors and biomaterials. This multidisciplinary approach, leveraging the expertise of scientists, bioengineers, and clinicians, aims to develop transformative therapies for previously untreatable conditions.

Stem cell research

Stem cell research has changed regenerative medicine, opening new possibilities for tissue repair and disease treatment. One significant advancement is the development of Induced Pluripotent Stem Cells (iPSCs). These are created by reprogramming adult cells and can differentiate into any cell type, making them invaluable for personalized therapies. Unlike embryonic stem cells, iPSCs alleviate ethical concerns. However, ethical issues related to human cloning persist (see below). Nonetheless, iPSCs serve as a crucial tool, offering safer and more efficient techniques for studying diseases, screening drugs, and developing personalized therapies. They also enable the replacement of damaged cells and the creation of functional tissues and organs, providing opportunities for organ transplantation and personalized tissue replacement treatments. Researchers have also achieved success in transdifferentiation, rapidly generating desired cell types for regenerative and transplantation therapies. The gene-editing tool CRISPR-Cas9, (see below), further enhances stem cell research by allowing precise modifications for disease correction and improved traits. Clinical trials have demonstrated the potential of stem cell-based therapies in various areas, including spinal cord injuries, neurodegenerative disorders, heart disease, blood disorders, and diabetes. Advancements in bioengineering and microfluidics have further improved stem cell growth and differentiation, bringing us closer to fully harnessing the power of stem cell-based regenerative medicine.

Tissue Engineering

Tissue engineering is a field that combines biology, engineering, and medicine to create functional tissues and organs. It has made advancements recently, such as the development of organoids used for studying diseases and personalized medicine. Biomaterials, like hydrogels, nanofibers, and 3D-printed scaffolds, play a role by providing support for cell growth. One challenge tissue engineering faces is creating blood vessels to ensure the tissues receive enough nutrients and oxygen. Researchers are using techniques like 3D bioprinting (see below), to create networks of tiny blood vessels within engineered tissues. 3D bioprinting allows for precise placement of cells and materials to create complex tissue structures. Decellularization, which removes cellular components from donor organs and replaces them with patient-specific cells, has also been successful in organ regeneration. Microfluidics and organs-on-a-chip platforms are used to mimic organ functions for studying diseases and testing drugs. Gene editing technologies like CRISPR-Cas9 (see below) show promise for modifying cells, enhancing tissue regeneration, and correcting genetic disorders.
Tissue engineering has achieved successes in various areas. Bladder tissues, tracheal replacements, skin substitutes, cartilage constructs, and liver models are some examples. In 1999, scientists successfully engineered and implanted bladder tissues in patients with bladder disease. In 2008, a tissue-engineered trachea was successfully implanted in a patient with a damaged airway. Tissue-engineered skin is commonly used for treating burn injuries, and advanced skin substitutes that closely resemble natural skin.

Electro-stimulation

Electro-stimulation, also known as electrical stimulation or electrotherapy, offers a non-invasive and safe method to enhance tissue regeneration and repair. It involves the use of specialized devices that deliver controlled electrical impulses to specific areas of the body. While electro-stimulation has a range of applications in medicine, one area where it shows promise is in tissue regeneration and enhancing the body's ability to heal itself. A common application is for the stimulation of nerves and muscles. Applying electrical currents to these tissues can restore or improve their function. For instance, in patients with nerve damage or muscle weakness, the technology can help to reactivate the nerves or strengthen the muscles, leading to improved mobility and functionality. Electrotherapy also promotes tissue healing and regeneration by enhancing cellular activity. Electrical currents can stimulate the production of growth factors, which are substances that promote cell growth and tissue repair. Additionally, the therapy can increase blood flow to a treated area, bringing oxygen and nutrients that are essential for tissue healing. In some cases, electro-stimulation is used in combination with other regenerative therapies, such as stem cell treatments. Electrical currents can help guide and enhance the differentiation and integration of stem cells into damaged tissues thereby accelerating the healing process. While further research is still needed to fully understand its mechanisms and optimize its use, electro-stimulation holds potential for improving outcomes in regenerative medicine and helping patients recover from various injuries and conditions.

Gene Editing

Gene editing is a field of research that holds potential to change regenerative medicine. At its forefront is CRISPR-Cas9, a powerful tool that allows scientists to make precise modifications to our genetic material. By combining gene editing with gene therapy, new avenues for treating genetic disorders and diseases can be explored. CRISPR-Cas9, derived from bacteria, acts like molecular scissors, enabling researchers to modify specific genes efficiently and cost-effectively, which means they can introduce beneficial changes, remove, or replace faulty genes, and correct genetic mutations.
Gene therapy, a key component of regenerative medicine, involves introducing functional genes into a patient's cells to compensate for defective or absent genes that cause specific disorders. There are two primary approaches to gene therapy: in vivo, which delivers therapeutic genes directly into the patient's body, and ex vivo, which modifies the patient's cells outside the body before reintroducing them.

Gene therapy has shown success in treating Leber Congenital Amaurosis (LCA), a rare disorder causing vision loss in children. Luxturna, the first FDA approved gene therapy for LCA, delivers a functional copy of the RPE65 gene into retinal cells, restoring vision in patients. Another example is gene therapy for Severe Combined Immunodeficiency (SCID), also known as "bubble boy disease". By using a modified retrovirus, this treatment restores immune function in infants with SCID caused by a deficiency in the enzyme adenosine deaminase. Promising results have also been observed in the treatment of inherited blood disorders such as Beta-Thalassemia and sickle cell disease, both caused by mutations in the hemoglobin genes. Clinical trials are focused on editing patients' own hematopoietic stem cells to correct these genetic mutations. Despite successes, there are still challenges to overcome, which include improving delivery methods, ensuring long-term safety, managing immune responses, and increasing treatment accessibility.

Challenges and ethical considerations

It is important to acknowledge the challenges and ethical issues, which accompany the field of regenerative medicine. One of its primary challenges is the complex and intricate nature of the human body. Developing therapies that can effectively repair and regenerate damaged tissues and organs is a daunting task that requires extensive scientific knowledge and technological expertise. The limited understanding of cellular behaviour, tissue interactions, and the intricacies of organ development present significant hurdles in translating regenerative medicine from the laboratory to clinical applications. In addition, regenerative medicine faces ethical considerations. One concern revolves around the use of embryonic stem cells, which are derived from human embryos. The destruction of embryos in the process raises ethical concerns, as it involves the termination of potential human life, which necessitates balancing the pursuit of medical advancements and respecting the moral value attributed to embryos. iPSCs have overcome ethical concerns associated with embryonic stem cells but raise ethical concerns of their own that are associated with their ability to clone humans, which we highlighted in the stem cell section above. Similarly, gene editing technologies like CRISPR-Cas9 have introduced new possibilities for manipulating genes and altering the genetic makeup of organisms, including humans. While gene editing presents significant opportunities for treating genetic diseases, it raises ethical questions about the modification of the germline, hereditary traits, and the potential for unintended consequences. International ethical frameworks need to be established to guide the responsible use of gene editing techniques and ensure that the potential benefits outweigh the associated risks.
 
Regulatory issues play a role in shaping the future of regenerative medicine. As the field progresses and new therapies emerge, regulatory bodies must establish clear guidelines and frameworks to evaluate the safety and efficacy of these treatments. Striking the right balance between fostering innovation and protecting patients' wellbeing is important for the development and implementation of regenerative medicine approaches. Public acceptance and understanding are paramount for the widespread adoption of these technologies. Educating the public about the science, potential benefits, and ethical considerations is essential to foster informed discussions and garner support. Building trust between the scientific community, regulatory agencies, and the public is essential to navigate the challenges and dilemmas inherent to regenerative medicine. Only with careful deliberation, collaboration, and responsible stewardship, will regenerative medicine contribute its full potential for solutions that improve health and wellbeing.
 
A role for governments
 
Government support for regenerative medicine is important for the development of innovative therapies for disabilities and diseases with limited treatment options. Administrations investing in R&D can result in therapies that address unmet medical needs and offer hope to patients. Many disabilities and diseases severely impact individuals' quality of life, hindering their daily activities and overall wellbeing. Governments have a public health obligation to foster the development of regenerative medicine, as it has the potential to restore or regenerate damaged tissues and organs, ultimately improving the lives of millions. In addition to the health benefits, regenerative medicine is a rapidly growing sector with significant economic potential. Appropriate support for R&D in this field can stimulate economic growth by creating high-skilled jobs and attracting investment from biotech and pharmaceutical companies. The successful development and commercialization of regenerative medicine therapies can also reduce healthcare costs, as they offer more effective treatments and alleviate the burden on healthcare systems.
 
Governments that prioritize R&D in regenerative medicine contribute to scientific advancements and potentially help to establish their countries as leaders in this emerging field. R&D facilitates collaboration between academia, industry, and healthcare institutions, driving innovation. This support aligns with principles of equity, access to healthcare, and the pursuit of scientific progress, demonstrating an administration's social and ethical responsibility to promote health and wellbeing among its citizens. Aging populations and increasing rates of chronic diseases and disabilities pose significant challenges to healthcare systems worldwide. Continuous treatments, hospitalizations, and long-term care result in substantial healthcare costs. By investing in R&D for regenerative medicine, governments can develop therapies that offer long-term solutions, reducing the need for costly and continuous interventions. This can lead to significant healthcare savings over time.
 
An international perspective

Countries worldwide are actively supporting R&D in regenerative medicine. The US is a leader in the area, with significant investment in R&D through organizations like the National Institutes of Health (NIH). Japan has established itself as a global leader with substantial funding, and supportive regulation with a streamlined approval process for regenerative medicine therapies.

These countries, and others, are actively engaged in advancing the field through funding, regulations, and collaboration, which aim to accelerate the development and commercialization of regenerative therapies.
 
Takeaways
 
We have presented a range of regenerative medicine technologies and described their advantages and challenges. We also mentioned that these technologies are developing at different rates and are often used together to create one therapy. So, what can MedTechs do to answer the question we posed at the beginning of this Commentary: Which technology or combination of regenerative medicine technologies will ultimately dominate in the next decade? While it is difficult to predict the future, it seems reasonable to suggest that the convergence of these evolving technologies will play a pivotal role in the transformation of regenerative medicine. Each technology brings both advantages and challenges, and their ultimate dominance will depend on several factors, including scientific breakthroughs, clinical success, regulatory considerations, and patient acceptance. To remain relevant and succeed in this arena, companies must recognize the urgency of intensifying their R&D efforts in regenerative medicine. This requires not only investing in cutting-edge technologies but also fostering collaboration between disciplines, institutions, and industry partners.

  • Stem cell study aims to improve prospects for lung cancer sufferers
  • Professor Sikora suggests that lung cancer is associated with poverty
  • Current therapies for lung cancer extend life by only a few months
  • Lung cancer kills more people than any other cancer

Lung cancer and cutting edge stem cell therapy

In 2015 a combined stem cell and gene therapy for lung cancer started its first clinical study in the UK. Professor Sam Janes of University College London, the study’s leader, said: “This will be the first UK cell therapy for lung cancer, and the biggest manufacturing of cells of its kind.” 

Dr Chris Watkins, director of translational research at the Medical Research Council, which is funding the study, said: “Lung cancer kills more men and women than any other cancer, and improving the outcome for patients with this terrible disease is one of the biggest challenges we face. This new therapy, which uses modified stem cells to target the tumour directly is truly at the cutting edge.”

 
Few studies
 
The use of stem cells for treating lung diseases has increasing appeal, but as yet, little is known about the effects of administering stem cell therapy to patients with lung diseases. Currently, there are only a small number of approved clinical studies in the US and Canada investigating cell therapy approaches for lung diseases. Patrick O’Brien a consultant obstetrician and gynaecologist at University College Hospital, London describes an initiative to create a national stem cell bank in the UK: 
 
       
 
Lung cancer
 
Lung cancer is the most common cancer worldwide, accounting for 1.8 million new cases and 1.6 million deaths in 2012. This year, an estimated 224,210 adults in the US, 40,000 in the UK, and 169,000 in India will be diagnosed with lung cancer, 90% of which are and caused by smoking. Of those diagnosed, 95% will die within ten years, although early stage lung cancer has a much better survival rate. Professor Karol Sikora, a world respected oncologist, and campaigner for better universal cancer treatment, suggests that lung cancer is associated with poverty:
 
    

Traditional therapies
 
Cell-gene therapy holds out new hope. “Lung cancer is very difficult to treat because the vast majority of patients are not diagnosed until the cancer has spread to other parts of the body. One therapy option for these patients is chemotherapy, but even if successful this treatment can normally only extend lives by a handful of months,” says JanesCurrent therapeutic strategies of chemotherapy, radiation therapy, and clinical studies with new-targeted therapies have only demonstrated, at best, extension in survival by a few months.
 
Innovative approach
 
“We aim to improve prospects for lung cancer patients by using a highly targeted therapy using stem cells, which have an innate tendency to home in on tumours when they’re injected into the body. Once there, they switch on a ‘kill’ pathway in the cancer cells, leaving healthy surrounding cells untouched,” says Janes. His study will test the treatment in human volunteers, firstly to check that the treatment is safe, and then in 56 lung cancer patients to see how effective the gene-cell therapy compares with standard care. Each patient in the study will receive three infusions comprised of billions of cells in parallel with chemotherapy.
 
Takeaways

A key advantage of Janes’ proposed treatment is that the cells do not have to be closely matched to a person’s tissue type or genetic profile. They are simply taken “off the shelf” from existing bone marrow supplies. This is because the cells have relatively few proteins on their surface, and do not induce an immune response in the recipient.
