Fig. 4From: In utero exposure to maternal smoking is associated with DNA methylation alterations and reduced neuronal content in the developing fetal brainCell proportion (CP) estimates by exposure and gestational age in the developing DLPFC. Bar plots show DNA methylation-based CP estimates of NPCs, NeuN+ and NeuN− (a–c, respectively) within fetal samples split by smoking exposure and gestational age. Significantly fewer (proportionally) NeuN+ were observed between smoking exposed (all samples) and unexposed (all samples)Back to article page
