NIH-3T3 cell proliferation assay on MCM, PCM and CCM.

(a) Fluorescence pictures that cells were cultured in three different matrix at 24, 48 and 72 h. (b) The number of NIH-3T3 cells adhered to the surface of materials at 24 h, 48 h and 72 h. (c) The cell viability of each test group (different leaching solution) at each observation time point. Scale bars: 100 μm. *: 0.01
