Figure 5. FGF prevents apoptosis of PSEN1−/− endothelial cells grown in the absence of serum.

Brightfield micrographs are shown of Psen1−/− cells grown in ECGM (A), serum-free media alone (B), or serum-free media supplemented with 25 ng/ml FGF1 (C), FGF1 with heparin and albumin (D), FGF2 (E), FGF2 with heparin and albumin (F), heparin and albumin (G) or VEGF (H). Scale bar, 25 μm.
