β-galactosidase expression activated by B6.EIIa-cre at postnatal day 0
 A) P0 head showing variable β-gal expression throughout the back of the head (2X magnification). |
 B) A different P0 head showing weaker β-gal expression overall, with stronger expression in specific brain regions (2X magnification). |
 C) The front of the head from the section in A (2X magnification). |
 D) The front of the head from the section in B (2X magnification). |
 E) The posterior cerebellum of the section in A (20X magnification). |
 F) The brain region from B, demonstrating strong β-gal expression (20X magnification). |
 G) The hippocamus/mid brain region from the section in A (20X magnification). |
 H) The hippocamal region from the section in B (20X magnification). |
| Note: Variable patterns of β-gal expression was observed with P0 pups in the same litter. The sex of these pups were not determined. | |
