摘要
Bovine demi‐embryos were produced by micromanipulation of day 6–7 embryos from superovulated cows. Monolayers of bovine oviduct epithelial cells (BOEC) were produced from slaughterhouse material. Half of the demi‐embryos were cultured on a confluent layer of bovine oviduct epithelial cells either in Hams F‐10 with 10% NCTC‐135 and with 10% FCS or in Earles Medium 199 with 10% FCS for 4–24 hours, followed by freezing of the survivors, while the corresponding other halfs were used for sexing. three 16‐Cell, 1 morula, 41 compact morulae, 4 early blastocysts, 7 blastocysts and 2 expanded blaszocysts were besected and cultured. An overall survival rate of 83% among the 63 in vitro cultured demi‐embryos was seen. Sechs bis sieben Tage alte Embryonen von superovulierten Rindern wurden mit Hilfe eines Mikromanipulators geteilt. Monolyer von bovinen Eileiterepithelzellen (BOEC) wurden aus Schlachthofmaterial gerüchtet. Eine Hälfte der Embryonen diente der Geschlechtsbestimmung, die andere Hälfte wurde auf konfluierenden Monolayern entweder mit Hams F‐10, 10% NCTC‐135 und 10′% FCS oder in TCM 199 rnit 10% FCS für 2 bis 4 Stunden kultiviert. Die überlebenden Stadien wurden eingefroren. Drei 16‐Zeller, 1 Morula, 41 kompaktierte Morulae, vier frühe und sieben Blastozysten sowie 2 expandierte Blastocysten wurden geteilt und kultiviert. Insgesamt betrug die Oberlebensrate bei 63 in vitro kultivierten Zwillingsembryonen 83%. Copyright © 1990, Wiley Blackwell. All rights reserved
