Stem Cell Biology

Stems cells are cells which are capable of dividing for indefinite periods in culture and produce multiple specialized cell types. These cells have the ability of developing into many tissues such as bone, brain, muscle, and other body tissues. Embryonic stem cells are primitive cells which are capable of differentiating to any adult cell (Kurkalli, Gurevitch, Sosnik, Cohn  Slavin, 1994).

Improvement in stem cell usage
Any injury to adult nervous system can be very devastating owing to the fact that neurons are incapable of regenerating after injury to assume the normal function. Insult to the central nervous system results in a break in communication as well as series of events that can lead to cell death. The discovery of stem cells which are capable of differentiating into neurons is a breakthrough in brain repair. It can be achieved through stimulation of stem cells present in the adult brain or through transplantation (Bruijn, 2007). The discovery of the use of these cells in carrying out brain repair after injury is the driving force in this explosive field of research. The idea of stem cells can also be involved in developing drugs and testing for their safety.

Concerns on the commercial use of the therapy
As much as the discovery is considered very important in treating brain damage, it is important for the scientists and clinicians to use it with a lot of caution, plan thorough studies on its use, and concentrate on the main laboratory experiments to provide answers to the challenges still facing this approach. For the therapy to be safe for use, it is important that adequate and necessary studies are carried out to learn about its properties and complexities of different stem cells available (Bruijn, 2007).
