Stem Cells Assignment Help
A stem cell isn’t fully grown and mature. However it has the potential of turning into specialized cells of various kinds in the entire body. Basically, there are two kinds of stem cells - adult stems cells and embryonic stem cells. Production of embryonic stem cells begins with the division of an egg that is ripe.
Adult stem cells contrary to what the name seems to suggest, can be seen in infants and children as well. Stem cells take residence in developed tissue. Their behavior resembles a repairing mechanism of some sort dividing and introducing newly specialized cells on a regular basis replacing those that are dead or can’t be found.
They are most likely to be found in tissues of the brain, blood, muscle, skin and bone. Research on adult stem cells is restricted as they are problematic to grow and differentiate in a laboratory.
For a very long time research is underway focusing on the biological aspect of stem cells. The expected results of the research are that new and emerging treatment of health issues
can be found. Since stem cells could lead to tissues found in the body, they therefore have the potential of unbounded medical application.
The aim of current research is to discover the ways and means of stem cells’ prevention and usage of diseases and injuries such as
- Parkinson’s disease
- type 1 diabetes
- heart disease
- spinal cord injury
- Duchene’s muscular dystrophy
- Alzheimer’s disease
- rheumatoid arthritis
- vision and
- hearing loss
Leukaemia, lymphoma and other blood disorders and a few solid tumors could be treated by stem cell procedures. As a matter of fact stem cell procedures could actually save lives of patients with these types of blood disorders.
Stem cell technology is not a cutting edge technology as it has been in use for over twenty years in bone marrow transplants. Bone marrow transplants entail replacing of the bone marrow stem cells of the patient with a healthy, matching donor’s bone marrow. Considering that the transplant is successfully done, the stem cells would then migrate into the bone marrow of the patient and start with the production of new and healthy leukocytes replacing abnormal cells.
Although a majority of blood stem cells are available in the bone marrow, small quantities can be found in the bloodstream. Peripheral blood stem cells are available in blood sample, which makes it easier to collect in comparison with bone marrow stem cells. However, peripheral blood stem cells are scarce in the bloodstream, so sufficient collection for the performance of a transplant could be challenging.
Umbilical cords historically have been rejected as a by-product of the process of being born. In recent times, however, the blood full of stem cell found in the umbilical cord has proven to be useful in the treatment of health problems akin to treatment with bone marrow stem cells and peripheral blood stem cells.
