GPH fiber scaffold regulates L929 cell proliferation. (A) Release curve of Tβ4 and aprotinin from GPH fiber scaffold. (B) Effects of extracts (the extracts concentration is 5% in cell culture medium) at a different time of PCL, PH and GPH scaffold to fibroblast cell (L929) proliferation. (C) Laser confocal images of L929 cells incubated with extracts of GPH scaffold (the extract concentration is 5% in cell culture medium) at different times for 24 h. a, 1 day; b, 2 days; c, 3 days; d, 5 days; e, 7 days. Fluorescently labeled cells represent viable cells. The data are shown as the means ± standard deviation from three independent experiments.
