STIM1 is expressed in vascular smooth muscle cells (VSMCs). (a) Detection of STIM1 by immunofluorescence in a rat balloon-injured carotid artery. STIM1 is labeled in red, with a-STIM1; the green fluorescence represents autofluorescence of elastin and identifies the media. m: media, ni: neointima (b) Western blots of total extracts from human coronary artery (CA), human and rat VSMC and of Jurkat T cells hybridized with anti-GOK/Stim. (c) Confocal imaging of hCASMC labeled with anti-STIM1 and anti-SERCA2 (IID8).
