Endogenous gene expression markers in established cell clones of the iPSC 194 cell
line: (a) OCT4, (b) SOX2, (c)
NANOG, (d) c-MYC (typical of pluripotent cells), (e)
MyoD (skeletal myoblast marker), and (f) BRACHYURY
(mesoderm marker). Human embryonal cells (ESC P27) served as a positive control. The
expression of the studied genes was normalized to the expression of two housekeeping
genes (ACTB and GAPDH). Samples: SkMC 194/6:
skeletal myoblast cells from patient no. 194 after the sixth passage; iPSC 194 cl.
10/11/13: clones 10, 11, and 13 of the induced pluripotent stem cell line no. 194 of
myoblastoid origin; ESC P27: embryonal stem cell line after the 27th passage. Values
are given as means ± SD; *p < 0.05, **p < 0.01, ***p < 0.001. ACTB: β-actin;
c-MYC: cellular c-Myc oncogene product; ESCs: embryonic stem cells; GAPDH:
glyceraldehyde 3-phosphate dehydrogenase; iPSCs: induced pluripotent stem cells; MyoD:
myogenic differentiation 1; OCT4: octamer-binding transcription factor 4; SOX2: sex
determining region Y - box 2.
