Stem cells are fundamental to biogenesis because they have the ability to self-renew and differentiate into various cell types. There are two primary types of stem cells:
Embryonic Stem Cells: These cells are pluripotent, meaning they can differentiate into almost any cell type. Adult Stem Cells: These cells are multipotent and can differentiate into a limited range of cells. For example, hematopoietic stem cells can differentiate into various blood cells.
