Degradable PHBHHx Modified by the Silk Fibroin for the Applications of Cardiovascular Tissue Engineering
Figure 12
SEM images of HUVECs morphologies in the scaffolds at different culture times. (a) and (c) show the cells cultured for 3, 5 days on the SF-modified PHBHHx scaffolds, respectively; (b) and (d) show the cells cultured for 3, 5 days respectively, in the PHBHHx porous scaffolds. The magnified images are at the top right corner of each image [28].
