STEM CEL THERAPY AND HUMAN CLONING
HUMAN STEM CELL RESEARCH AND THERAPY AND ALSO HUMAN CLONING : Today,I will discuss the very interesting and fascinating topic and scientific achievement,namely,human stem cell research and therapy along with human cloning. The intention is to take on various world leaders and religious leaders who have been misleading the people of the world on this subject either due to their ignorance or arrogance or false dogmas. The stem cells have a remarkable potential to differentiate into various specific cell types in the body to serve as a repair system for the body and to replenish other cell types.The stem cells have 2 basic features namely self-renewal indefinitely and differentiation into specific cell type.The stem cell are of 2 types namely Embryonic Stem Cell(ESC) and Adult Stem Cell(ASC).The ESC can differentiate into 220 specific cell types like heart cell,blood cell,bone cell etc etc. The stem cell therapy is useful to treat […]
