Fig. 9.
Schematic representation of the distribution of p73-positive cells in E12 mouse brain at various levels from rostral (A) to caudal (D). p73-positive cells are shown as black dots. On theright, Reln-positive, p73-negative cells are represented as open circles, indicating the partial dissociation between p73 and Reln at this stage. Highest p73 expression is in the choroid plexus (in black). Arrowheadspoint to those regions (in gray) where p73-IR cells are found in the deep ventricular zone, suggesting local generation. These regions correspond to the cortical–choroid junction or cortical hem inB and C, a well as to its rostral (A) and caudal (D) extensions, and to the strionuclear neuroepithelium (C). A, amygdala;ChP, choroid plexus; Hy, hypothalamus;LGE, lateral ganglionic eminence; MGE, medial ganglionic eminence; LV, lateral ventricle;OB, olfactory bulb; SN, strionuclear neuroepithelium; T, thalamus; TT, taenia tecta; VP, ventral pallium.
