Hormones Direct Neurons Differently in Male and Female Mice (image) American Association for the Advancement of Science Share Print E-Mail Caption This shows a sexually dimorphic pattern of mouse mammary gland neuronal innervation prior to male gland regression. Blue: nucleic acid staining showing the rudimentary mouse mammary gland; yellow: Tuj1 staining showing the neuronal fibers innervating the mouse mammary gland. This image relates to a paper that appeared in the Dec. 7, 2012, issue of Science, published by AAAS. The paper, by Yin Liu at Howard Hughes Medical Institute in Baltimore, Md., and colleagues was titled, "Sexually Dimorphic BDNF Signaling Directs Sensory Innervation of the Mammary Gland."
