Figure 7: CFTR immunodetection by confocal analysis. Confocal scans are shown in the horizontal cross-section () plane and vertical cross-section () plane. (a) CFBE41o- cells; (b) hAMSCs- CFBE 1 : 5 ratio; (c) hAMSCs- CFBE 1 : 10 ratio; (d) hAMSCs- CFBE 1 : 15 ratio; (e) hAMSCs alone. The white arrows point to CM-DiI-labelled hAMSCs expressing CFTR on their membrane (green signal). Note in (d) that hAMSCs harbour some CFTR-specific signal in discrete regions under the apical plasma membrane.
