Confocal fluorescent micrographs showing ac, e, f nestin (green) and d P75NTR (green), af S100 (red) immunoreactivity in sagittal cryosections of 17 pcw human foetal olfactory system. Scale bars 40 μm. a White arrowheads show nestin immunoreactivity surrounding the outside of S100+ OECs in cross-sections of olfactory nerves (ON). b Nestin immunoreactivity surrounding ONs and between OEC-axon units (white arrowheads) in longitudinal sections of ONs appears similar to P75NTR immunoreactivity d in adjacent tissue sections. c Nestin immunoreactivity in the olfactory epithelium (OE) and lamina propria (LP). e, f White boxes show magnified areas of nestin+ S100− cells (white arrows) in the ONL. e also shows nestin+ cells around a blood vessel asterisk in the ONL
