Induced pluripotent Stem Cells: Where we are currently?

Abstract

Induced Pluripotent Stem Cells (iPSCs) are a type of pluripotent stem cells generated by reprogramming an adult somatic cell genome to the stage of a pluripotent stem cell in vitro by inducing a forced expression of specific transcription factors that are important for the maintenance of pluripotency. The iPSCs seem to be very similar to Embryonic Stem Cells (ESCs) in terms of morphology, cell surface markers and gene expression levels, but recent studies have demonstrated some differences between the two cell types. However, iPSCs might have potential application in regenerative medicine, transplantation, drug testing, disease modelling, and avoidance of tissue rejection and with less ethical concern than ESCs. This paper aims to present the most important characteristics of iPSCs which have therapeutic significance.
