- Аннотация: Induced pluripotent stem (iPS) cells can be derived from a wide range of somatic cells via overexpression of a set of specific genes. With respect to their properties, iPS cells closely resemble embryonic stem cells. Because of their main property, pluripotency, iPS cells have excellent prospects for use in substitutive cell therapy; however, the methods of directed differentiation of iPS cells have not been yet sufficiently elaborated. In this work, we derived human iPS cells from fetal neural stem (FNS) cells by transfection with a polycistronic plasmid vector carrying the mouse Oct4, Sox2, Klf4, and c-Myc genes or a plasmid expressing the human OCT4 gene. We have shown that human FNS cells can be effectively reprogrammed despite a low transfection level (10%-15%) and that the use of 2-propylvaleric (valproic) acid and BIX-01294 increases the yield of iPS cell clones to similar to 7-fold. Further, transient expression of OCT4 alone is sufficient for reprogramming. The iPS cells obtained express all the major markers of embryonic stem cells and are able to differentiate in vitro into ectodermal, mesodermal, and endodermal derivatives. In addition, we have found that the human iPS cells derived from FNS cells can be successfully subjected to in vitro directed chondrogenic differentiation to form functional cartilaginous tissue.
