Feature analysis of human iPS cells derived from human umbilical vein endothelial cells. A, B - immunohistochemical analysis of iPS cells, antibodies stain to specific markers of pluripotency Oct4 (A) and SSEA-4 (B). The specific signals are stained with green (A) and red (B), nuclei in (B) are stained with blue (DAPI). C - embryonic bodies, derived from iPS cultured in suspension. Bar scale - 100 mkm. D - interphase nucleus in iPS cells stained with active chromatin marker H3me2K4 (red). White arrows localize the chromosome region of partly reactivated X - chromosome
