Question

Write a short note on Stem cells.

Answer 1

Stem cells are undifferentiated, unspecialized cells capable of self-renewal through mitotic cell division and differentiation into various specialized cell types. They have the unique ability to develop into different tissues, making them vital for growth, repair, and regeneration. There are three main types of stem cells based on potency: totipotent (can form a complete organism), pluripotent (can form almost all cell types), and multipotent (can form a limited range of cells within a family). In mammals, stem cells include embryonic stem cells, fetal stem cells, and adult stem cells.
