The Study on Biocompatibility of Porous nHA/PLGA Composite Scaffolds for Tissue Engineering with Rabbit Chondrocytes In Vitro
Figure 2
SEM images of the porous PLGA/n-HA composites. (a) SEM image of the three-dimensional porous PLGA/n-HA composite (50x). The outside diameter is around 0.6 mm. (b) SEM image of the internal structure of the PLGA/n-HA composite (1000x). The pore diameter ranges from 100 μm to 300 μm and the porosity reaches up to 90%.
