Figure 7.
Marked macrophage infiltration and increased rate of proliferation in the adventitia of the vascular lesions. Cryosections of mesenteric arteries from Ctrl (control) or Y/T KO (YAP/TAZ [yes-associated protein 1/WW domain containing transcription regulator 1] knockout) mice treated with Ang II (angiotensin II) or vehicle. A, Immunostaining for Mac2 (galectin 3) demonstrates pronounced infiltration of monocytes/macrophages in the adventitia of hypertensive Y/T KO vascular lesions. B, The thickened adventitia of Y/T KO vascular lesions is associated with intense cell proliferation (Ki-67), whereas the media displays no obvious signs of cell proliferation. DAPI (4′,6-diamidino-2-phenylindole) was used as a nuclear stain. Elastin autofluorescence is shown in green. H&E indicates hematoxylin and eosin.
