Embryonic and Adult (bone marrow)
|
Detailed explanation-1: -There are several main categories: the “pluripotent” stem cells (embryonic stem cells and induced pluripotent stem cells) and nonembryonic or somatic stem cells (commonly called “adult” stem cells).
Detailed explanation-2: -Embryonic stem cells can differentiate into a wider range of cell types, but are difficult to obtain. The best source is the five-day-old embryo. Adult stem cells will differentiate into a narrower range of cell types. Bone marrow transplants are an example of adult stem cell transplant.
Detailed explanation-3: -There are two main branches of stem cells in the BM, including hematopoietic stem cells (HSCs) and mesenchymal stem cells (MSCs). Adult BM-derived HSCs have long been recognized as a precursor to all blood cell lineages including erythrocytes, platelets, and white blood cells.
Detailed explanation-4: -The embryonic stem cells can be totipotent, pluripotent, oligopotent, multipotent, and unipotent.
