Figure 1.

Biotinylated-MAR^ab or MTD^ab were injected into the cerebral ventricles of E14 embryonic mice. (A,B) Coronal sections run in parallel for biotin amplification showed biotin-MAR^ab-labeled cells in the VZ and SVZ (A), whereas biotin-MTD^ab did not label cells (B). Note: erythrocytes produced nonspecific labeling in MAR^ab and MTD^ab. (C–G) RG neural stem cells were positive for biotin-MAR^ab. Arrowheads indicate RG pial fibers; arrows indicate RG ventricular process. (H,I) biotin-MAR^ab+ cells (green) co-localized with the RG cell marker vimentin (red). Scale bars: (A,B) 100 µm; (C–H) 10 µm.
