Percentages of CFTR+ hAMSCs labelled with CM-DiI in co-cultures with CFBE-F508del cells

Percentages of CM-DiI⁺CFTR⁺ cells were obtained by plotting the FLH-1 channel, identifying CFTR-specific green signal, against FLH-2 channel, identifying red-labelled hAMSCs. Percentages of CFTR-expressing hAMSCs in whole CM-DiI⁺ population were obtained by dividing the double-positive hAMSCs for all CMDiI⁺ cells (with and without green signal). As hAMSCs are stained with CM-Dil, the same percentage is present in both columns. Data are shown as the mean ± SEM of three experiments. Significance is referred to CFTR⁺ cells in the whole CM-DiI⁺ population in all conditions as compared with hAMSCs alone.
