The Study on Biocompatibility of Porous nHA/PLGA Composite Scaffolds for Tissue Engineering with Rabbit Chondrocytes In Vitro
Figure 4
Microscopic images of cells of control group A and experimental group B at different time points (100x). After 1 day in culture, cell density in group A (a) and group B (b) was low. The cells were observed triangle-shaped, disc-shaped, and megagon-shaped. After 3 days in culture, the cells in group A (c) and group B (d) were observed to connect by cellular processes. After 5 days in culture, cells in group A (f) and group B (e) increased and completely covered the surface of the composite.
