Figure 1From: In vitro evaluation of Panax notoginseng Rg1 released from collagen/chitosan-gelatin microsphere scaffolds for angiogenesisScanning electron micrographs of GMSs and the CC-GMS scaffold. A-B: Scanning electron micrographs of GMSs. C: Scanning electron micrographs of the CC-GMS scaffold. The average inner pore size of the CC-GMS scaffold was 110 ± 12 μm, and the diameters of the GMSs were between 10 and 50 μm.Back to article page
