Transcriptional regulation of retinal progenitor cells derived from human induced pluripotent stem cells
Abstract
In order to develop effective cures for diseases and decipher disease pathology, the need exists to cultivate a better understanding of human development. Existing studies employ the use of animal models to study and model human development and disease phenotypes but the evolutionary differences between humans and other species slightly limit the applicability of such animal models to effectively recapitulate human development. With the development of human pluripotent stem cells (hPSCs), including Human induced Pluripotent stem cells (hiPSCs) and Human Embryonic Stem cells (hESCs), human development can now be mirrored and recapitulated in vitro. These stem cells are pluripotent, that is, they possess the potential to generate any cell type of the body including muscle cells, nerve cells or blood cells. One of the major focuses of this study is to use hiPSCs to better understand and model human retinogenesis. The retina develops within the first three months of human development, hence rendering it inaccessible to investigation via traditional methods. However, with the advent of hiPSCs, retinal cells can be generated in a culture dish and the mechanisms underlying the specification of a retinal fate can be determined. Additionally, in order to use hiPSCs for successful cell replacement therapy, non-xenogeneic conditions need to be employed to allow for fruitful transplantation tests. Hence, another emphasis of this study has been to direct hiPSCs to generate retinal cells under non-xenogeneic conditions to facilitate their use for future translation purposes.
