Figure 1. Expression of the TP receptor in the endothelium of rat middle cerebral arteries.

Figure 1

A) RT-PCR amplification of mRNA transcripts for TP receptor (439 bp) and KCa2.3 channels (514 bp) from rat MCA. bp = base pairs B) Localization of TP receptor and PECAM-1-immunoreactivity in whole mount preparations of rat MCA. TP receptor-immunoreactivity was present in the endothelial cell layer (PECAM-1-positive). Orientation of cell nuclei was determined using DAPI. The merged image demonstrates coexpression of TP receptors and PECAM-1, indicating TP receptor expression in the endothelial cells of rat MCAs. Scale bar, 20 µm.
