Confocal micrographs of MSCs spread and proliferate on various scaffolds.

<p>At day 1 (A) and day 3 (B) cells penetrated to scaffolds with different cells infiltration distance for 1 day (a) and 3 days (b). Improved cell proliferation and infiltration were observed on scaffolds with CAP treatment and/or microspheres incorporation compared to PCL only control group. Data are mean ± standard error of the mean, N = 3, *p<0.05.
