Figure 3

The cell morphology of TSPCs on different matrix surfaces. (a) Cell morphology observation: (A–C) cell morphology under a light microscope; (D–F) the morphology of TSPCs under a confocal laser scanning microscope. The nuclei were stained blue; the cytoskeletons were stained red; (A, D) TSPCs in the cell culture plate; (B, E) TSPCs on the smooth SF film; (C, F) TSPCs on the SF film with a microstructure. (b) Analysis of cell morphology: (A–D) cell body aspects; (E–H) cell body major axis angle (I–L) cell area; group C: TSPCs on the cell culture plate; group S: TSPCs on the smooth SF film; group G: TSPCs on the SF film with a microstructure; .
