Degradable PHBHHx Modified by the Silk Fibroin for the Applications of Cardiovascular Tissue Engineering

Figure 7

OD values of the human fibroblasts on the SF-modified porous PHBHHx scaffolds at different culture times, with porous PHBHHx scaffold as control: PHBHHx with pore size between 50~75 μm. 0.75% silk fibroin was used for the modification. Error bars represent means ± SD for 𝑛=4. *𝑃<0.05 [19].
