Antibody:	Anti-Bai1 H-270 sc-66815
Detection system:	Secondary antibody coupled to Alexa Fluor 555

Structure	Level	Pattern	Image	Note
TS23: brain vascular element	Present	Regionally restricted	3A , 3A'' , 3A'	Expression was detected only in the vessels of the dorsal cerebral cortex and hippocampus.

Structure	Level	Pattern	Image	Note
TS27: brain blood vessel	Present		3B'' , 3B' , 3B	Expression was expanded at P2 and was detected toward the more dorsolateral and ventral cortical areas reaching up to the piriform cortex. Expression was absent in subcortical areas.

TS28: brain blood vessel	Present	Non-Uniform	3C , 3D left , 3C' , 3C'' , 3D center	Expression was strong in all cortical microvessels and in some of the lateral striatal vessels and dorsal thalamic nuclei, but not in ventral thalamic and hypothalamic vessels. Expression was high at the tips of the sprouts and branching points.
