Fig. 2From: Conditional knockout of leptin receptor in neural stem cells leads to obesity in mice and affects neuronal differentiation in the hypothalamus early after birthThe level of activated pSTAT3 stimulated by leptin decreased in the ARH-A and ARH-C of Shh-cKO mice compared with control littermates. a Experimental scheme. Shh-cKO mice or control littermates at P35 received a single i.p. injection of leptin and were sacrificed after 1 h. b Schematic diagrams depicting the indicated brain regions for analysis. c-h Representative images showing leptin-activated pSTAT3 and NeuN expression in the indicated subregions of the hypothalamus of Shh-cKO mice and control littermates. Scale bars, 100 μm. I Quantification of the ratio of pSTAT3 + NeuN+ cells to total NeuN+ cells (n = 4 mice for each genotype). ***p < 0.001; Student’s two-tailed, unpaired t-test.
