Localization and expression of GnRH-R in HBEC.

<p><b>A.</b> Representative confocal images of HBEC co-stained by cell markers CK13 (mucous cells, left panel, red labelling) and Muc5AC (ciliated cells, middle panel, red labelling) and GnRH-R (green labelling). Co-distribution of GnRH-R (green labelling) and CFTR (red labelling) was observed in ciliated cells, in apical cell membranes. <b>B.</b> Representative immunoblot performed to assess GnRH-R expression in 6 different HBEC cultures.
