COmPLICATIONS OF THE STEM CELL THERAPY in liver cell failure

Stem cells are undifferentiated cells that proliferate and are characterized by their ability to self-renew and form one or more differentiated cell types. Stem cells normally replenish tissue lost through the wear and tear of aging, after injury or disease.Stem cells are divided into; those that are isolated from the embryo, known as embryonic stem cells, and those that are isolated from the adult somatic tissue known as adult stem cells. Stem cells are classified according to their differentiation capability into; pluripotent stem cells that are capable to differentiate into three somatic germ layers that comprise an organism and multipotent cells which differentiate only into cells of one tissue or germ layer.Clinical researches that were accomplished during last few years on stem cells have constituted a revolution in regenerative medicine and cancer therapies by providing the possibility of generating multiple therapeutic useful cell types. These new cells could be used for treating numerous genetic and degenerative disorders including; hematopoietic disorders, heart failure, chronic liver injury, Parkinson’s disease and Alzheimer’s disease. Also, many clinical findings raise the possibility for treatment of infertility through the therapeutic use of stem cells.
