Because of important species specific differences between animal and human heart, however, drugs that are toxic to the human heart have occasionally entered clinical trials, sometimes resulting in death.One of the hottest topics in stem cell research today is the study of induced pluripotent stem cells (iPS cells).While the promise of stem cell therapies excites us, it also energizes YouTube creators to craft entertaining skits.Much adult stem cell research to date has aimed to characterize their potency and self-renewal capabilities.Studies on cancers of germinal cells (teratocarcinomas) beginning about 50 years ago established that cancers arise from stem cells and that cancers contain stem cells.

New studies indicate that it may be possible to direct the differentiation of human embryonic stem cells in the cell culture to form insulin-producing cells that eventually could be used in transplantation therapy for diabetics.Modern therapeutics is having a lot of hope from stem cell research in the field of organ transplantation and replacement of lost tissue.Pleuripotent stem cells are the descendents of totipotent cells and can differentiate into cells derived from 3 germ layers.In 1981, it was proved that mouse Embryonic Stem (ES) cells are derived from the inner cell mass of blastocysts.In developed countries, stem cell transplant has become a therapeutic option but in developing countries, it is still under trial phase.This article focuses on types of stem cells and stem cell regulation with enlightening comments on clinical application and future aspects.
