ISH of 5-LO and FLAP mRNA analyses in human LNs and mucosa of the Waldeyer tonsillar ring.
Bright fields of the (A) paracortical area of LN 5-LO antisense or (B) paracortical area of LN sense; (C) central paracortical area 5-LO antisense; (D) paracortical area FLAP antisense; (E) LN GC 5-LO antisense; (F) same as panel E, but with a higher magnification of inset; (G) mucosa overlying the Waldeyer tonsillar ring 5-LO antisense; or (H) mucosa overlying the Waldeyer tonsillar ring FLAP antisense. There were no specific ISH signals observed for 5-LO sense (panel B) or FLAP sense probes (data not shown). The arrows indicate 5-LO or FLAP mRNA+ cells. Bars indicate 20 μm.
