Figure 1From: Fibroblast-myofibroblast transition is differentially regulated by bronchial epithelial cells from asthmatic children Time course of α-SMA expression in HLF cultures. The expression of α-SMA by HLF cultures is shown following initial seeding through Day 7 (start of co-culture exposures). Expression of α-SMA at Day 7 of culture was 25 fold higher than Day 1 (p < 0.0001).Back to article page
