Abstract (original English)
VEGF-induced Ca2+ signalling was investigated in CD133+/VEGFR-2+ progenitor cells isolated from human adipose stroma. Colonies derived from CD133+ immunoselected cells displayed inhomogenous Ca2+ signals, with variable magnitude of VEGF-induced Ca2+ entry, which positively correlated with expression of the Ca2+ channel protein TRPC3. High levels of VEGF-induced Ca2+ entry and TRPC3 expression were preferentially detected in rim areas of expanding colonies. Dominant negative suppression of TRPC3 inhibited VEGF-induced Ca2+ entry into CD133+ cells. Our results identify TRPC3 as a key Ca2+ entry channel in a subset of CD133+ stem cells. We suggest TRPC3 as an essential determinant of cell fate in CD133+ progenitor-derived colonies.
