Figure 8. The bi-phasic effect exerted by 2-APB on store-operated Ca²⁺ entry in endothelial colony forming cells.

5 µM 2-APB enhances SOCE induced by thapsigargin (TG), whereas 50 µM inhibits it, in both N-EPCs (A) and RCC-EPCs (B). The traces are representative of, respectively, 51 and 57 cells from at least three independent donors. Thapsigargin was administrated at 2 µM.
