Stem Cell Research
Stem cells comprise natural in the human body capable of differentiating into different specialized cells (Cummings, 2009). These cells are also capable of self-renewal whereby they reproduce into more stem cells. Mammals produce two types; adult and embryonic stem cells. Embryonic stem cells are harvested from the inner cell mass of embryos in the blastocyst stage. Embryo cells differentiate into all the organs and tissues that form the human body. Adult stem cells are present in various tissues within the body (Cummings, 2009). These cells are responsible for body repairs and replenishment.
