Fig 4. Prolactin receptor immuno reactivity in human LAM lung lesions.

Histological sections from LAM patients were analyzed. Human lung tissues were obtained from subjects who underwent lung resection for diagnostic reasons and immunohistochemical-staining using the PrlR antibody clone 1A2B1 (Invitrogen) was carried out. Arrows indicate the location of PrlR immuno reactivity in one microscope field of a representative image from LAM tissue; compared to positive cells for PrlR in control lung tissue. For negative control, primary antibody was omitted, Scale bars: 50 μm.
