Embryonic stem cells are derived from embryos and have the potential to develop into any type of cell in the body. Adult stem cells are found in various tissues and can give rise to specific types of cells in that tissue.
Fetal tissues are not the only source of stem cells. Stem cells can also be found in other sources such as bone marrow, umbilical cord blood, and adult tissues like adipose tissue. These sources provide alternative options for stem cell research and therapy.
There are two main types of stem cells: embryonic stem cells, which are derived from embryos, and adult stem cells, which are found in adult tissues and can differentiate into a limited range of cell types. Additionally, induced pluripotent stem cells (iPSCs) are adult cells reprogrammed to behave like embryonic stem cells.
Embryonic stem cells can be obtained from early-stage embryos. Adult stem cells are found in various tissues throughout the body, such as the bone marrow or brain. Induced pluripotent stem cells are created by reprogramming adult cells, like skin cells, to develop stem cell properties.
Stem cells are considered as undifferentiated cells. They will divide and divide forming more stem cells. The two main stem cell types are embryonic stem cells and adult stem cells. Only the embryonic stem cells can become any type of tissue. Embryonic stem cells have the potential to become any type of cell in the body. There is news as of 2015 that perhaps blindness can be cured using these embryonic stem cells.
Hematopoietic stem cells (HSCs) and mesenchymal stem cells (MSCs) are two types of stem cells that can be derived from a hemocytoblast, which is a precursor cell in the bone marrow. HSCs give rise to blood cells, while MSCs have the potential to differentiate into various cell types such as bone, cartilage, and fat cells.
