Which medium do PromoCell recommend to use on HUVEC - Endothelial Cell Growth Medium or Endothelial Cell Growth Medium 2?

The standard medium for isolation and propagation of our HUVEC, HUAEC, HPAEC, and HSaVEC is Endothelial Cell Growth Medium (C-22010). It contains ECGS, an extract from bovine hypothalamus which has mitogenic effects on endothelial cell proliferation. Scientists who prefer a more defined Growth Medium can use Endothelial Cell Growth Medium 2 (C-22011). In this medium, ECGS is replaced by VEGF, IGF, and additional bFGF and EGF to stimulate endothelial cell growth.
