Forebrain progression of A2bp1 label at E13.5 resembles expression seen at E12.5 with the addition of labeling in the cortical plate. The A2bp1 expression in the neocortex presumptively includes both locally generated cells, as well as interneurons from the LGE which are tangentially migrating in the intermediate zone. The majority of the labeling in the cortex at this age is in the emerging cortical plate. CxP = Cortical plate; lms = lateral migratory stream; AH = anterior hypothalamus; cnV = cranial nerve V; Amyg = amygdala. Scale bar = 1 mm.
