tissue stem cells or adult stem cells
There are two main types of stem cells: tissue stem cells and adult stem cells.
Tissue stem cells, also known as embryonic stem cells, are derived from early-stage embryos. These stem cells have the potential to differentiate into any type of cell in the body, making them highly versatile.
On the other hand, adult stem cells are found in various tissues and organs in the body. These stem cells are more specialized and can only differentiate into specific types of cells within their respective tissue or organ. For example, hematopoietic stem cells in bone marrow can differentiate into blood cells, while mesenchymal stem cells found in bone marrow or adipose tissue can differentiate into bone, cartilage, or fat cells.
Both tissue stem cells and adult stem cells have therapeutic potential for various medical conditions. Tissue stem cells offer broader differentiation potential, while adult stem cells provide a more targeted approach for specific tissues or organs.
