Regulation of stem/proliferative, secretory, and absorptive cell markers

Expression of each stem/proliferative (A), secretory (B), and absorptive (C) markers is shown as a ratio of day 4, 7, or 10 to day 2 as presented in Figure 1C. Plots are colored according to time point (darker colors are later time points) and each symbol represents a separate sample (distinct donor, replicate). As in Figure 1C, 2–3 time courses are presented for each culture, and each time-course experiment includes three cell-culture (technical) replicates. All gene expression analyses were performed by qPCR.
