FIG. 4.

Localization of RED mRNAs in Paneth cells of rhesus macaque jejunum. Sections of monkey jejunum were hybridized to a RED-4 prosegment cDNA probe as described in Materials and Methods. (A and B) Hybridization with anti-sense-strand and sense-strand riboprobes, respectively, shown at a magnification of ×95. Arrows indicate the base of jejunum crypts occupied by Paneth cells. Note the absence of hybridization with the negative control sense-strand probe in panel B. (C) Like panel A but shown at a magnification of ×380. Arrows indicate strongly positive individual Paneth cells.
