Survival (based on morphological evaluation) and nuclear maturation of dromedary camel GV-oocytes after exposure to different combinations of cryoprotectants.

<p>(A) Percentages of morphologically normal oocytes in dromedary camel COCs exposed to various vitrification solutions; VS1 (20% EG plus 20% DMSO), VS2 (25% EG plus 25% DMSO) or VS3 (25% EG plus 25% glycerol); (B) Percentages of in vitro matured oocytes (oocytes at MII-stage) after IVM of dromedary camel GV-oocytes exposed to different vitrification solutions. Data are presented as the means ± S.E.M. Different small letters indicate significant differences at <i>P ≤</i> 0.05.</p

Cumulus cell expansion following in vitro maturation of dromedary camel oocytes vitrified at the germinal vesicle stage using different vitrification solutions and cryodevices.

<p>Percentages of IVM oocytes showing expanded cumulus cells after vitrification with VS1 (20% EG plus 20% DMSO) or VS2 (25% EG plus 25% DMSO) and with traditional straws, OPS (open pulled straws), SSV (solid surface vitrification) and Cryotop. Data are presented as the means ± S.E.M. Different small letters indicate significant differences at <i>P ≤</i> 0.05.</p
