Bai1 is differentially expressed on growing blood vessels during mice brain development. Tissue-level characterization of Bai1 expression at E15 (A), P2 (B) and P14 (C, D) showed that Bai1 was expressed by cortical blood vessels throughout development (A’, B’ and C’). Initially expressed only by cortical vessels (A’, A”), however, as development progresses, striatal and thalamic vessels also started to express but weakly and non-homogeneously (A”, B”, and C”). Interestingly, at P14, expression was not homogenous in all blood vessels and especially notable on small dense microvessels in the cortex (D).
