1. Stem Cells: Core Idea and Classification
- Stem cells are non-specialised, immature cells that can self-renew by mitotic cell division and differentiate into a wide range of specialised cell types.
- The first stem cells were isolated from blood cells.
- In humans, stem cells are found in the umbilical cord, placenta, inner cell mass of the early embryo, few tissues of the foetus, and in some adult organs.
2. Stem Cells Based on Source
- Embryonic stem cells are also called early stem cells.
- Embryonic stem cells are present in the inner cell mass of the blastocyst after around five days of development.
- Embryonic stem cells are self-reproducing pluripotent cells and are possibly immortal.
3. Stem Cells Based on Potency
- Totipotent stem cells are the most versatile stem cells.
- Totipotent cells can produce the embryo, extra-embryonic membranes, and all post-embryonic tissues and organs that form a complete organism.
- The zygote is a totipotent cell.
4. Adult Stem Cell Types and Plasticity
- Hematopoietic stem cells are found in bone marrow and also in fetal blood and fetal bone marrow.
- Hematopoiesis is the formation of different blood cells in bone marrow.
- HSCs give rise to RBCs, monocytes, neutrophils, acidophils, basophils, lymphocytes, and platelets.
