From: Expression of Cre recombinase in dopaminoceptive neurons
Cre activity in embryonic and adult brain in R26RD1Cre mice. (a) Cre activity is analyzed by expression of beta-galactosidase activity (blue staining) at E10.5. The reporter mice are heterozygous for the R26R allele. Positive signal is present in the developing brain at this stage in the tectum above the mesencephalic fold (boxed area), as shown also in (d, arrowhead). In the adult brain, beta-galactosidase activity analyzed in coronal vibratome sections is present in striatum (b,e), cortex (b,f) and hippocampus (c). CA2: hippocampus CA2 field; DG: dentate gyrus; VI: layer VI of the cortex. Magnification: (a) 20×, (d) 40×, (b,c) 50×, (e,f) 100×.
