Figure 4From: Participation of the oviductal s100 calcium binding protein G in the genomic effect of estradiol that accelerates oviductal embryo transport in mated ratsCellular uptake of the FITC-MO in the rat oviduct. Photomicrographs of rat sections after 5 hours of intraoviductal injection of FITC-MO/Endo Porter mixture (A) or Endo-Porter alone (B). Note that arrows point strong green fluorescence representing cellular uptake of FITC-MO mainly in the luminal epithelium demonstrating penetration of MO in these cells in vivo. e = epithelium, sm = smooth muscle, L = lumen.Back to article page
