What are stem cells?
Stem cells are mother cells that has the function of becoming any type of cell in the body. One of the main features of stem cells is their functionality to self-renew or multiply while maintaining the ability to change into other types of cells. Stem cells are able to become cells of the blood, bone, heart,muscle, brain, skin etc. There are different types of stem cells but they can have the same capacity to develop into multiple types of cells.
Potential of Stem Cells
Scientists first studied the potential of stem cells in mouse embryos over two decades ago. Over years of research they discovered the properties of these stem cells in 1998. They found methods to isolate stem cells from human embryos and grow the cells in the laboratory .Early studies used embryos created for infertility purposes through in vitro fertilization procedures and when they were no longer needed for that purpose. The use required voluntary donation of the embryos by the owners.(National institute of health 2015)
Stem cell research is improving by leaps and bounds. These may soon become the basis for treating diseases such as

What is Stargardt’s disease and how can it be treated?
Stargardt’s disease is a type of disease that is genetically inherited to their children when both parents carry mutations of a gene associated with vitamin A processing in the eye. Parents can carry recessive genetic traits responsible for Stargardt's, even though they themselves may not have the disease.
