Stem cells

Stem cells come in three diffrent variations Embryonic stem cells, Adult stem cells, and Induced pluripotent stem cells. Diseases that might be treated by transplanting cells generated from human embryonic stem cells include Parkinson’s disease, diabetes, traumatic spinal cord injury, Duchenne’s muscular dystrophy, Heart disease, and vison and hearing loss.

pluripotent stem cells offer a possibility of renewable source of replacement cells and replacement tissues to a bunch of diseases, disabilities and conditions such as Parkinson's disease, amyotrophic lateral sclerosis, spinal cord injury, burns, heart disease, diabetes, and arthritis. Some disadvantages of stem cells being used in treatments include: embryonic stem cells can treat diseases and regenerating organs but they are harvested from human fetus’s sometimes the treatment might not work Ex. Somebody needs a bone marrow transplant and this transplant uses adult stem cells but then the treatment might not work because the adult stem cells die.

Stem cells show potential for many different areas of health and medical research, and studying them can help us understand how they transform into the dazzling array of specialized cells that make us what we are. Some of the most serious medical conditions, such as cancer and birth defects, are caused by problems that occur somewhere in this process. A better understanding of normal cell development will allow us to understand and perhaps correct the errors that cause these medical conditions.One kind of stem cell—human embryonic stem cells—has generated much interest and public debate. Pluripotent stem cells (cells that can develop into many different cell types of the body) are isolated from human embryos that are a few days old. Pluripotent stem cell lines have also been developed from fetal tissue (older than 8 weeks of development).
