Multipotent stem cells
Regardless of how complex the idea is, stem cells remain an exciting area of research due to its potentials of curing serious diseases. One factor that complicates the already confusing matter about stem cells is the separation of such into various categories. One would be the separation of multipotent stem cells from totipotent and pluripotent stem cells.
So what are multipotent stem cells in the first place? Aside
from having the same basic feature of all stem
cells, multipotent stem cells has also the ability to renew itself
from long periods of time and differentiate into specialized cells
with specific function, such as to give rise to other types of cells.
A good example of multipotent brain cells would be those cells in
the brain that gives rise to different neural cells and haematopoietic
These cells can give rise to different types of blood cells, but they can't create brain cells. Another example would be our bone marrow; it also contains multipotent stem cells but limited only to blood cell types.
It's fair to say that adult stem cells are multipotent because of its limitation to one or more cell lines. Mesenchymal cells, however, is a multipotent cell that can give rise to several cell types. It gives rise to the bones, cartilage, fat, and similar tissues. Essentially committed to produce specific type of cells: pluripotent, which gives rise to almost any cell type or totipotent ones for any cell, including the potential to reproduce organism.
Multipotent stem cells can be found in the tissues of mammals, particularly
the adults. They are responsible for replenishing the body's cell
throughout an individual's life since they replaced diseased or aged
Multipotent cells were derived from pluripotent cells, thus making them partially differentiated and they continue specializing as they develop. These multipotent cells are essential in transplants. They can be isolated and develop into certain type of cells before being transplanted back to the patient's tissue. And unlike embryonic stem cells, multipotent stem cells are quite acceptable ethically because the extraction procedure does not involve any embryo abortion.
One major type of multipotent stem cells that research is currently focused on is the neural cell. This brain cell can be isolated from the adult and fetal brain tissues --- can be divided, or differentiate --- into new nerve cells. This breakthrough in science will make spinal and brain injuries reversible in the future.
