Fig. 3From: Morphological, molecular and FTIR spectroscopic analysis during the differentiation of kidney cells from pluripotent stem cellsRelative gene expression levels of mouse pluripotent stem cells (Oct4, SOX2), renal progenitor cells (PAX2, WT1) and adult kidney cells (PAX2, WT1, Ksp) at different points in time. Triplicate real-time PCR was performed. Expression levels were normalized against β-actin. Bars represent mean ± SD of N = 3 with 3 biological replicates. Asterisk indicate differentiated kidney cells at specific time points of differentiation that showed statistically significant (p < 0.001) in relative expression respect to mouse pluripotent stem cells (day 0 of differentiation)Back to article page
