Effects of UC-collagen and UCE for hCB-EPC culture.

<p>(A) Proliferation capacity of hCB-EPCs on UC-collagen and cultured in 5% FBS or varied concentrations of UCE (0.1, 0.5, and 1.0 mg/ml) (*#<0.05). (B) Attachment and proliferation capacity of 0.5 mg/ml UCE medium compared with 5% FBS medium on UC-collagen-coated plates as shown in optical microscopy images (10×). (C) Quantification of hCB-EPC proliferation at different passage numbers. (D) Measurement of hCB-EPC survival cultured in 0.5 mg/ml UCE- or 5% FBS-containing medium after a freeze-thaw cycle.
