Caracterización del complejo cúmulus-ovocito (CCO) en las diferentes fases del desarrollo folicular en alpacas (Vicugna pacos)

Abstract

El presente estudio tuvo como objetivo caracterizar el complejo cúmulus ovocito (CCO) en las diferentes fases del desarrollo folicular en alpaca. Se emplearon 24 alpacas hembras, dependiendo del tamaño del folículo y en la fase de desarrollo folicular que se encontraba la alpaca, fueron clasificadas en 5 grupos: G1=Fase Selección (5-6 mm), G2=Fase Dominancia I (7-8 mm), G3=Fase Dominancia II (9-10 mm), G4=Fase Dominancia III (>10 mm) y G5= Fase Atresia. Luego, fueron sometidas a laparotomía paramedial para extraer el ovario. El ovocito fue aspirado del folículo y observado bajo un estereoscopio. Los CCO fueron clasificados en acorde al número de capas de células del cúmulus y por la apariencia del citoplasma en: Grado 1, COC con células del cúmulus compacto, mayor o igual a 5 capas, y con citoplasma homogéneo; Grado 2, COC con células del cúmulus compacto, entre 2 a 4 capas y con citoplasma homogéneo; Grado 3, células del cúmulos menos compacta, mayor o igual a 1 capa, o parcialmente denudado, y citoplasma de apariencia irregular con zonas oscuras; y Grado 4, ovocito denudado, y citoplasma irregular, con zonas oscuras. Los resultados demostraron que no había diferencias estadísticas significativas para ninguna de las fases. Por lo que podríamos obtener cualquier grado en cualquiera de las fases del desarrollo folicular.
