Figure 6: CFTR mRNA expression in hAMSCs and hAECs. CFTR on hAMSCs and hAECs upon isolation (T0) and on hAMSCs at passages one (P1) and three (P3). Upper panels: CFTR; lower panels: β-actin. M: molecular weight markers; Ctr+: positive control (nasal brushing); Ctr−: negative control (no RT). On the right, arrows indicate the specific band along with PCR-product length.
