Flow through collagen gels linear
WebOct 15, 2005 · Collagen gels (2 mg/ml), seeded with 5×10 5 fibroblasts/ml, were cast in an interstitial flow chamber as previously described (Ng and Swartz, 2003). The set-up was immersed in media overnight for cell attachment at 37°C, 5% CO 2 in an incubator. For the induction of flow, the chamber was connected to a reservoir of growth medium via a ... WebThe permeability of 1.98 mg/mL, 3.5 mg/mL, and 5 mg/mL collagen Type I rat tail hydrogels were determined experimentally by tracking the pressure drop across the gels as water flowed through the samples, which simultaneously compressed them under pressure. The Holmes-Mow model was used to fit the permeability as the gels underwent compression.
