Effect of inactivated feeder cells of two segments of the oviduct on the in vitro development of bovine embryos

Descripción del Articulo

The aim of this study was to evaluate the effect of inactivated feeder cells (feeder layer system) from two segments of the bovine oviduct (isthmus and ampulla) in the in vitro development of bovine embryos. Cell lines from segments of the isthmus and ampulla were generated and subsequently inactiva...

Cell lines from segments of the isthmus and ampulla were generated and subsequently inactivated with mitomycin C (40 μg/ml) to inhibit their ability to divide and eliminate competition for nutrients with embryos. Bovine oocytes were matured in vitro for 24 h and were fertilized for 18 h in conventional culture with Brangus bovine semen. The expected fertilized oocytes were cultured for seven days in the feeder layer system with isthmus and ampulla cells separately at a concentration of 1.44 x 10 5 cells/ml. The best results in the production of in vitro bovine embryos were obtained with ampullary cells (280/84, 30%) in comparison with the isthmus cells (278/75, 26.9%) and the control group (275/73, 26.5%) in a conventional system. It is concluded that the cells of the oviduct can fulfill functions like those that the oviduct fulfills in the in vivo process, improving the in vitro production of embryos.El objetivo del estudio fue evaluar el efecto de células alimentadoras inactivadas (sistema feeder layer) provenientes de dos segmentos del oviducto bovino (istmo y ámpula) en el desarrollo in vitro de embriones bovinos. Se generaron líneas celulares de segmentos del istmo y ámpula para posteriormente ser inactivadas con mitomicina C (40 µg/ml) para inhibir su capacidad de división y eliminar la competencia por nutrientes con los embriones. Se maduraron in vitro ovocitos bovinos por 24 h y fueron fertilizados por 18 h en cultivo convencional con semen bovino Brangus. Los ovocitos supuestamente fertilizados fueron cultivados por siete días en el sistema feeder layer con células de istmo y ámpula separadamente a una concentración de 1.44 x 105 células/ml. Se obtuvo mejores resultados de producción de embriones bovinos in vitro con células ampulares (280/84; 30%) en comparación con las células del istmo (278/75; 26.9%) y el grupo control (275/73; 26.5%) realizado en un sistema convencional. Se concluye que las células del oviducto pueden cumplir funciones similares a las que cumple el oviducto en el proceso in vivo, mejorando la producción in vitro de embriones.Universidad Nacional Mayor de San Marcos, Facultad de Medicina Veterinaria2019-07-05info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistasinvestigacion.unmsm.edu.pe/index.php/veterinaria/article/view/1609410.15381/rivep.v30i2.16094Revista de Investigaciones Veterinarias del Perú; Vol 30 No 2 (2019); 768-774Revista de Investigaciones Veterinarias del Perú; Vol. 30 Núm. 2 (2019); 768-7741682-34191609-9117reponame:Revista UNMSM - Revista de Investigaciones Veterinarias del Perúinstname:Universidad Nacional Mayor de San Marcosinstacron:UNMSMspahttps://revistasinvestigacion.unmsm.edu.pe/index.php/veterinaria/article/view/16094/14078Derechos de autor 2019 Gleni T.
