Stem Cell Technology — Prelims Strategy

Prelims Strategy

For Prelims, a strong conceptual foundation is paramount. Begin by clearly understanding the definition of a stem cell, its two core properties (self-renewal and potency), and the distinct characteristics of Embryonic Stem Cells (ESCs), Adult Stem Cells (ASCs), and Induced Pluripotent Stem Cells (iPSCs).

Focus on their origin, relative potency (pluripotent, multipotent, unipotent), key molecular markers, and the primary ethical considerations associated with each type. Memorize the 'Yamanaka factors' and their role in iPSC creation.

Identify the most established clinical application (Hematopoietic Stem Cell Transplantation for blood disorders) and distinguish it from experimental therapies. Pay close attention to the Indian regulatory body, ICMR, and its 'National Guidelines for Stem Cell Research, 2017', particularly the prohibitions (e.

g., reproductive cloning) and mandatory requirements (e.g., CTRI registration, 14-day rule for embryo research). Current affairs related to new clinical trial approvals or major research breakthroughs in India are also important.

Practice MCQs that test conceptual clarity, factual recall, and the ability to differentiate between similar-sounding terms or applications. Create flashcards for key terms like pluripotency, multipotency, organoids, and therapeutic cloning.
