PEDF and VEGF-A Output from Human Retinal Pigment Epithelial Cells Grown on Novel Microcarriers

PEDF concentration time course. The PEDF concentration in the media from the hRPE cells on the different microcarriers was measured with an ELISA. After a short rising phase the PEDF concentration reached a plateau. The hRPE cells on Hillex II, Plastic Plus, and ProNectin F microcarriers secreted comparable amount of PEDF, whereas hRPE cells on the CultiSpher microcarriers did not secrete significant amounts of PEDF.
