A scanning electron microscopy study of frozen thawed dog sperm during In vitro gamete interaction Palomino Mackenney, Jaime; Reyes Solovera, Mónica de los (Wiley, 2009)The aim of this work was to study the effects of cryopreservation on the binding and penetration of dog spermatozoa to the zona pellucida (ZP) by scanning electron microscopy (SEM). The sperm-rich fraction of six ejaculates ...

Reyes Solovera, Mónica de los; Palomino Mackenney, Jaime; Parraguez Gamboa, Víctor; Ramírez Moyano, Fernando (Elsevier Inc., 2017)The aim of this study was to determine the mRNA LHR and LHR protein expression pattern in the canine ovarian follicles at different stage of development throughout the estrous cycle. Dog ovaries were obtained from 1-6y ...

Palomino Mackenney, Jaime; Herrera, Giannina; Torres-Fuentes, Jorge; Dettleff, Phillip; Patel, Alok; Martínez, Víctor (Elsevier B.V., 2017)© 2017 Elsevier B.V. In pelagic species such as Seriola lalandi, survival of both the eggs and embryos depends on yolk processing during oocyte maturation and embryo development. The main enzymes involved in these processes ...

Castro Sánchez, Rodrigo; Palomino Mackenney, Jaime (Univ Zulia, Facultad Ciencias Veterinarias, 2016)This research aims to characterize the pattern of expression of BMP-15 during in vitro maturation of canine oocyte. BMP-15 is a follicular factor related to the oocyte maturation, taking part in cumulus cells expansion and ...

Palomino Mackenney, Jaime; Flores Becerra, Javiera; Ramírez Saboya, Georges; Parraguez Gamboa, Víctor; Reyes Solovera, Mónica de los (MDPI, 2021)The oestrous cycle in canines is specifically more extended than that in other mammals. This implies that the oocytes do not reach maturity within the ovarian follicle but undergo final maturation in the oviducts. Besides ...

Ramírez, George; Palomino Mackenney, Jaime; Aspée Mallanes, Karla; Reyes Solovera, Mónica de los (MDPI, 2020)Simple Summary The knowledge of physiological events associated with canine reproduction involving oocyte developmental potential is essential to increase the success of reproductive biotechnologies in this species. In ...

Reyes Solovera, Mónica de los; Palomino Mackenney, Jaime; Gallegos, Carola; Espinoza, Roberto; Dettleff Faúndes, Phillipe; Peralta Troncoso, Óscar; Parraguez Gamboa, Víctor; Ramírez, George (CSIRO, 2020)The aim of this study was to evaluate the expression of connexin (Cx) 37 and Cx43 in canine cumulus-oocyte complexes (COCs) during the oestrous cycle. Cx localisation was analysed by immunohistochemistry and immunofluorescence, ...

Palomino Mackenney, Jaime; Herrera, Jaime Giannina; Dettleff, Jaime Phillip; Martínez, Jaime Víctor (socbiol@huelen.reuna.cl, 2014)© 2014 Palomino et al. Background: During fish oocyte maturation, specific molecules are expressed and accumulated within oocyte until fertilization and embryo development. Special attention have been paid in members of ...

Dueñas, Fernando; Becerra Ivanovic, Víctor Ignacio; Cortés Araya, Yennifer Alejandra; Vidal Vilches, Sonia; Sáenz Iturriaga, Leonardo Enrique; Palomino Mackenney, Jaime; Reyes Solovera, Mónica de los; Peralta Troncoso, Óscar (BIOMED, 2014-07-10)Background: Mesenchymal stem cells (MSC) are multipotent progenitor cells characterized by their ability to both self-renew and differentiate into tissues of mesodermal origin. The plasticity or transdifferentiation ...

Cortez Chica, Jahaira Azucena; Bahamonde, J.; Reyes, M. de los; Palomino Mackenney, Jaime; Torres, C.; Peralta, O. A. (Wiley, 2018-06)Contents Mesenchymal stem cells (MSC) are multipotent progenitor cells defined by their ability to self-renew and give rise to differentiated progeny. Previous studies have reported that MSC may be induced in vitro to ...

Palomino Mackenney, Jaime; Reyes Solovera, Mónica de los (Elsevier Inc., 2016)© 2016 Elsevier Inc. This study aimed to investigate the expression profiles of growth differentiation factor 9 (GDF-9) and bone morphogenetic protein 15 (BMP-15) mRNA in canine oocytes and follicular cells throughout ...
-
Reyes Solovera, Mónica de los; Hetz Rodríguez, Jennifer; Palomino Mackenney, Jaime (WILEY-BLACKWELL PUBLISHING, INC, 2009-07)The aim of the present study was to compare the ultrastructure of the surface of the zona pellucida (ZP) of immature and in vitro matured dog oocytes using scanning electron microscopy (SEM). Bitch oocytes were collected ...
