K-N: In human 11pcw brains, IGSF10 expression pattern was similar to that observed in mouse, with GnRH neurons interspersed in an IGSF10-positive NM (K-N, frontal sections, see also schematic in P). IGSF10 positive cells were also detected in the olfactory bulb (OB, panel O). Sense probe resulted in no specific signal (panel N).
