Fig. 10.

Different types of cells cultured in 2D (on flat PDMS), quasi-3D (in PDMS microwells), and 3D (in Matrigel) microenvironments. (A) Fluorescence micrographs of stained hMSC, HFF, and HUVEC with F-actin in red, vinculin in green, and nuclei in blue. (B) Statistic results (n ≥ 90 per group) of integral intensity of F-actin and vinculin, and cell adhesion parameters after 4 h culture of cells in 2D and quasi-3D, and 24 h culture of cells in 3D.
