Observations Regardin Oocyte in Vitro Maturation after Recovery from Slaughter House Females

Valeriu Carabă, Alexandra Ivan, Nicolae Păcală

Abstract


The oocytes viability must be taken as an important selection parameter for successful in vitro cultivation. The ovaries were collected from the slaughterhouse and maintained at 4°C for 7 days. Fallowing cumulus -oocytes complexes recovery the viability was tested using two staining methods. For the first experiment we used 27 cumulus - oocytes complexes, stained with Neutral red and for the second experiment we used 11 cumulus - oocytes complexes stained with Trypan blue. Fallowing staining with Neutral red 23 cumulus - oocytes complexes were assessed as viable (were stained in red – enzymatic activity within the cells) and for the Trypan blue staining 11 cumulus - oocytes complexes were assessed as viable (remained unstained – integers cellular membranes).
