Stem cells are attracting attention as a key element in future medicine, satisfying the desire to live a healthier life with the possibility that they can regenerate tissue damaged or degenerated by disease or ageing. Stem cells are defined as undifferentiated cells that can replicate and differentiate into various tissue cells. Stem cells, commonly encountered in clinical or preclinical stages, are largely classified into embryonic, adult, and induced pluripotent stem cells. Recently, stem cell transplantation has been frequently applied to the treatment of pain as an alternative or promising approach for the treatment of severe osteoarthritis, neuropathic pain, and intractable musculoskeletal pain that do not respond to conventional medicine.
The main idea of applying stem cells to neuropathic pain is based on the ability of stem cells to release neurotrophic factors, along with providing a cellular source for replacing the injured neural cells, making them ideal candidates for modulating and possibly reversing intractable neuropathic pain. Studies show that it is helpful for patients who continue to experience symptoms despite conventional treatments. The principle behind this approach lies in regenerative medicine, where stem cells are believed to help reduce inflammation and create a biological environment that supports tissue healing.
In musculoskeletal conditions such as knee degeneration or disc-related back pain, the primary benefit seen so far appears to be pain modulation rather than complete structural regeneration. Some patients report improvement in mobility and daily function, largely due to the anti-inflammatory and reparative signals released by these cells. However, it is important to note that clinical outcomes vary widely and depend on factors such as the stage of disease, overall health, and the specific technique used.
From an evidence-based perspective, stem cell therapy is still evolving. In appropriate cases, surgery may remain the most effective and predictable option. Equally important are safety and regulatory considerations. Patients should be cautious of unregulated practices and seek treatment only at accredited centres that follow scientific protocols and ethical standards. Clear counselling and realistic expectations are essential. While stem cell therapy holds promise for the future, its current role should be viewed with cautious optimism, guided by clinical judgement and ongoing research.
