Up-regulation of typical stem cell markers in simulated microgravity (SMG). Levels of gene expression for the stem cell phenotype (OCT4, SOX2, SOX17, PDX1) in hBTSCs cultured in presence of Kubota’s Medium (KM) and hormonally defined medium (HDM) on Cytodex 3 microcarriers in normal gravity condition (NG, control) (a) and in SMG (*p < 0.05; §p < 0.01; n = 4) (b).
