From: The secretions of oviduct epithelial cells increase the equine in vitrofertilization rate: are osteopontin, atrial natriuretic peptide A and oviductin involved?

Figure 1

Influence of oviduct cells and/or cumulus cells on equine IVF. A) In vitro fertilization rates (IVF, percentage of fertilized oocytes per matured oocytes) of equine gametes co-incubated with or without porcine vesicles; the IVF rates in the two groups are significantly different (*: P ≤ 0.05); B) Equine and porcine cell monolayers observed by microscopy at magnification ×400. C) IVF rates of equine gametes co-incubated with equine or porcine vesicles or cell monolayers; the IVF rates in the four groups are not significantly different (P > 0.05); D) IVF rates of denuded oocytes or cumulus-oocyte complexes (COCs) in the presence of porcine vesicles; the IVF rates in the two groups are not significantly different (P > 0.05). The fractions represent the number of fertilized oocytes out of matured oocytes (oocytes in metaphase II, activated and fertilized).
