1. Grasping Stem Cells
1.1 Description of Stem Cells
- Stem cells are primitive cells endowed with the distinct capability to transform into specialized cell forms. They can replicate indefinitely through cellular division.
- Two primary categories of stem cells exist:
- Embryonic Stem Cells (ESCs): Obtained from early embryonic stages.
- Adult Stem Cells (ASCs): Located in diverse body tissues; these possess more restricted differentiation compared to ESCs.
1.2 Classifications of Stem Cells
- Totipotent Stem Cells: Capable of differentiating into any cell type.
- Pluripotent Stem Cells: Can become any cell type barring extra-embryonic tissue.
- Multipotent Stem Cells: Able to develop into a limited variety of cell types.
- Unipotent Stem Cells: Restricted to differentiate into a sole cell type.
2. Present Status of Stem Cell Research in India
