Stem cells can be used to study development. Stem cells may help us understand how a complex organism develops from a fertilised egg. In the laboratory, scientists can follow stem cells as they divide and become increasingly specialized, making skin, bone, brain, and other cell types. They are harvested during a process called in-vitro fertilization. This involves fertilizing an embryo in a laboratory instead of inside the female body. Adult stem cells can’t differentiate Author: Jacquelyn Cafasso.
Adult stem cells. These stem cells are found in small numbers in most adult tissues, such as bone marrow or fat. Compared with embryonic stem cells, adult stem cells have a more limited ability to give rise to various cells of the body. Until recently, researchers thought adult stem cells could create only similar types of cells. Stem Cell Treatments Due to the ability of adult stem cells to be harvested from the patient, their therapeutic potential is the focus of much research. Adult stem cells, similar to embryonic stem.
Currently, blood stem cells are the only type of adult stem cell used regularly for treatment; they have been used since the late 1960s in the procedure now commonly known as bone marrow transplant.Transplants of neural stem cells have been tried in small numbers of patients with brain disorders such as Parkinson disease, and the FDA recently approved a clinical trial of neural stem cells . Many scientists believe that Alzheimer’s patients will benefit from stem cells in a different way before the development of potential cell transplantation therapies. By using stem cells derived from Alzheimer patients to grow large numbers of brain cells in the lab, scientists can .
