Stem cell therapy is gaining popularity in India to treat a wide variety of medical conditions including Leukaemia, Thalassemia, damaged cornea and severe burns. Describe briefly what stem cell therapy is and what advantages it has over other treatments?

Stem cells are unspecialised cells with two defining abilities: self-renewal and the potential to differentiate into specialised cell types. Stem cell therapy uses these cells to repair, replace or regenerate damaged tissue.

What stem cell therapy is

• Types: embryonic (pluripotent), adult/somatic (multipotent, e.g. bone-marrow), and induced pluripotent stem cells (iPSCs) reprogrammed from adult cells.
• Mechanism: healthy stem cells are introduced to regenerate diseased tissue, as in bone-marrow transplants for leukaemia and thalassemia, corneal repair, and skin grafts for burns.

Advantages over other treatments

• Regenerative, not merely symptomatic: it can restore function rather than manage symptoms.
• Curative potential for otherwise intractable blood disorders and tissue damage.
• Reduced rejection with autologous (patient's own) or iPSC-derived cells.
• Personalised medicine and a renewable cell source for research and drug testing.

Caveats

Ethical concerns over embryonic sources, risk of tumour formation, and unproven commercial claims require strict regulation, as under the ICMR-DBT National Guidelines for Stem Cell Research.

Used responsibly, stem cell therapy offers a genuinely regenerative frontier in medicine.
