Coronal anterior (A) and posterior (C) ionized calcium-binding adapter molecule 1 (Iba1)-labelled sections through a 10.5-gestational week (gw) human fetus. Grey areas vary in colour according to the density of Iba1-positive cells. (B,D) Iba1-labelled sections at the level of the corresponding boxes in A and C. Cluster 1a is in the thalamus (Th) extending along the dorsal Th (A,C), cluster 1b in the ventricular zone of the ganglionic eminence (GE) zone, and cluster 3a in the genu of the internal capsule (IC) (B). Patches 3a, 3b, and 3c are located at the junction of the IC with the Th, external capsule (EC), and cerebral peduncle (CP), respectively. Patch 2 surrounds the optic tract (OT). ChP, Choroid plexus; VZ, ventricular zone. Scale bars: B and C, 500 μm. From Fig. 3 in Monier et al. (2006).
