Relative collagen production per HAEC and HASMC normalized to Control. (A) Collagen released into media between Days 5 and 7 of HAEC culture. One-way ANOVA (F(2,11) = 48.885, p < 0.001). N = 5. (B) Collagen laid down in ECM at the end of 7 days of HAEC culture. One-way ANOVA (F(2,6) = 36.943, p < 0.001). N = 3. (C) Collagen released into media between Days 5 and 7 of HASMC culture. N = 5. (D) Collagen laid down in ECM at the end of 7 days of HASMC culture. N = 3. * = p < 0.05, ** = p < 0.01, *** = p < 0.001, *** = p < 0.0001.
