#MyoendothelialJunctions are 🔗s between #MuralCells and #Endothelia, elsewhere separated by the #BasementMembrane. I show how #Brain #PrecapillarySphincters are 🔥spots for these junctions (yellow dots), like Rhodin showed in 🐇 #PeripheralTissue: https://tinyurl.com/cm8chj56 (7/15)

Results: In this study of the #MICrONS 🐭👁️-cortex 3D #ElectronMicroscopy dataset, I show how the shape of #Contractile #MuralCells transition from #PenetratingArteriole to #PrecapillarySphincter to #Capillaries. Vascular lumen = blue, mural cells = various colors (5/15)
