(Figure 7), it is found that the addition of PCLA- viability, as shown in Figure 8. Setting the absorbance
PEG-PCLA (5 mg/mL) did not influence the growth result of blank control each day as 100%, it can be found
of fibroblasts and showed a similar growth tendency that over 80% of viability of fibroblasts was maintained at
compared with blank control. Furthermore, CCK-8 assay a PCA concentration of 5 mg/mL after co-cultivation for

was also used for the quantitative evaluation of the cell 24 h, and the viability increased further with a decrease
