Regenerative Medicine in Orthopaedics and Trauma: Challenges, Regulation and Ethical Issues.

The ability of stem cells to self-renew and differentiate into cell types of different lineages forms the basis of regenerative medicine, which focuses on repairing or regenerating damaged or diseased tissues. This has a huge potential to revolutionize medicine. It is anticipated that in future, stem cell therapy will be able to restore function in all major organs. Intensive research has been on-going to bring stem cell therapy from bench to bedside as it holds promise of widespread applications in different areas of medicine. This is also applicable to orthopaedics, where stem cell transplantation could benefit complications like spinal cord injury, critical bone defects, cartilage repair or degenerative disc disorders. Stem cell therapy has a potential to change the field of orthopaedics from surgical replacements and reconstructions to a field of regeneration and prevention. This article summarizes advances in stem cell applications in orthopaedics as well as discussing regulation and ethical issues related to the use of stem cells.
