Stem cells in review

In recent years, many progresses have been made in the field of the stem cell researches that is a promising novel therapeutic strategy for the incurable disease. These cells exist in all multicellular organisms, having an ability to divide and differentiate into a diverse range of specialized cell types and they also can replace the lost and damaged cells. Stem cell’s property of self-renewal and their potency have been proposed a promising usage of these cells in the future in regenerative medicine, cell therapy and drug researches. Recent technologies provide an unlimited source of autologous and non-autologous stem cells. Stem cell therapy has some restrictions so further research to improve our biological understanding is essential. In present paper, basic concepts, applications, limitations and the prospect of using stem cells for future use have been reviewed.
