Cumulated collagen production from cells of in vitro maintained and of in vivo implanted hydrogels. Note that most of the collagens from the in vitro cultures were found in the culture medium (middle bar). Mean values (n = 6) and standard deviations are shown. In vitro gel: collagen content of the in vitro cultured hydrogel; in vitro gel + medium: collagen content of the in vitro cultured hydrogel plus the collagen released into the combined medium supernatant from two weeks of culture; in vivo: collagen content of the in vivo implanted hydrogel. Statistic: paired t-test comparing the in vitro group (gel + medium) and the in vivo group, * = p < 0.05.
