MUC5AC and congenital adrenal hyperplasia: However, the CAH increased from 0.182 ± 0.010 for the monolayers to 0.312 ± 0.025 for differentiated hTCEpi cells (Figure 2C, p = 2.9 × 10−4), consistent with previous reports.[24] Intriguingly, the observed CAH was not significantly different between control and mucin‐deficient differentiated hTCEpi cell layers (Figure 2C, p = 0.104), suggesting that the observed increase in CAH following differentiation is not attributable to the expression of membrane‐tethered mucins during the differentiation process.
