FIG. 1.

The effect of fractional volume occupancies (FVOs) from 0% v/v to 54% v/v of the Ficoll mixture, polyvinylpyrrolidone (PVP) 360 kDa and PVP 40 kDa on (A) collagen I deposition and (B) proliferation of human dermal fibroblasts (HDFs). *p<0.05, **p<0.01 versus controls. Data are expressed as mean±SD, calculated from triplicates. Corresponding immunocytochemistry (ICC) images in (A) show collagen I deposition in red counterstained with 4′,6-diamidino-2-phenylindoldilactate (DAPI) for cell nuclei in blue.
