From: Localization of heat shock protein 20 in swine carotid artery
Lack of stimulus dependence of HSP20 localization in swine carotid arteries. Cross-sectional representative confocal micrographs showing the distribution of HSP20 immunostaining in swine carotid artery that was A) unstimulated (top), B) treated with 10 μM histamine for 30 min (second from top), C) treated with 10 μM histamine for 30 min with 10 μM nitroglycerin added for the last 20 min (third from top), and D) treated with 10 μM histamine for 30 min with 10 μM forskolin present for the last 20 min (bottom). The image is 140 microns wide. The micrographs show that the distribution of HSP20 did not appreciably change during histamine stimulation or relaxation induced by nitroglycerin or forskolin.
