Expression of growth factor leading-edge genes is recovered during very small embryonic-like stem cell (VSEL)-derived sphere (VSEL-DS) formation. qRT-PCR analysis of the growth factor leading-edge genes (AKT3, ELK1, MAP2K1, SOS1, SHC1, GRB2, CSNK2A1 and RPS6KA3) in freshly FACS-sorted VSELs and cells isolated from VSEL-DS. The expression level is represented as the fold difference relative to the value for VSELs and is presented as the mean ± SD of at least 3 independent experiments. *P<0.05 and **P<0.01 compared with VSELs. The graphs are ordered by the fold-change during VSEL-DS formation.
