Final answer:
Two examples of stem cells in adults include hematopoietic stem cells in bone marrow that form blood cells and epithelial stem cells that regenerate skin cells. Adult stem cells maintain and repair tissue, are multipotent, and crucial for the body's self-renewal and repair.
Step-by-step explanation:
Stem cells in adults are responsible for a myriad of essential regenerative and repair functions. Two examples of stem cells working in adults include:
- Hematopoietic stem cells in the bone marrow that give rise to red blood cells, white blood cells, and platelets, playing a critical role in maintaining our blood system.
- Epithelial stem cells, which constantly regenerate and give rise to keratinocytes, the cells that make up a large portion of the epidermal layer of our skin.
Adult stem cells are highly valuable as they maintain and repair the tissue in which they reside. They are multipotent, which means they can give rise to several specialized cell types that form part of tissue-specific or organ-specific systems. Their continuous division and regeneration ability help the body to renew and repair itself.
