Fig. 5: lncRNA expression in accessory glands.

a CR43622 RNA localized to single foci in main cell nuclei. b CR44591 localized in multivesicular bodies in secondary cells. c CR44585 localization in main cell cytoplasmic foci and secondary cell multivesicular bodies. d CR44542 cytoplasmic localization in secondary cells. e Luminal localization of CR43426 below the secretory cell layer. f CR44606 localization in the cytoplasm of both main and secondary cells (and lumen – not shown). g Double-labeling of CR18854 and CD63-GFP in the multivesicular bodies of secondary cells. Patterns appear to be more complementary than overlapping. h Higher magnification of CR18854 and CD63-GFP-labeled particles in the accessory gland lumen. Particles are non-overlapping and differ in size. i Co-localization of CR18854 and CR43752 in accessory gland lumenal particles. Insets show higher magnification views. Scale bars = 20 μm.
