Oocyte-derived forms of ruminant BMP15 and GDF9 and a theoretical model to explain their synergistic response [PDF]

open access: yes, 2016
Bone morphogenetic factor 15 (BMP15) and growth differentiation factor 9 (GDF9) are two oocyte-secreted factors with well documented effects on ovarian follicular development and ovulation-rate.

Calcitonin‐like diuretic hormone influences reproduction in adult female Rhodnius prolixus

open access: yesInsect Science, EarlyView.
Highlights • CT/DH‐like immunoreactivity is present in female reproductive tissues • CT/DH receptor transcripts are expressed in the fat body and ovaries • RNAi knockdown of CT/DH receptors reduces egg number and hatching rate • Rhopr‐CT/DH increases RhoprVg1 and RhoprVgR expression in ovaries in vitro • Rhopr‐CT/DH stimulates oviduct contractions in a

Impact of xenotransplantation of sheep ovarian cortex and follicular fluid- enriched SMART medium on the morphology of recovered of sheep oocyte [PDF]

open access: yesMirror of Research in Veterinary Sciences and Animals, 2017
Ovarian follicles and cortical tissue can survive viable after ovariectomy and use successfully for xenotransplantation or in vitro maturation. This study designed to assess in vitro maturation (IVM) of sheep oocytes recovered from immature follicles ...

LsFAMeT and LsJHAMT coordinate JH biosynthesis to regulate fecundity in Laodelphax striatellus

open access: yesInsect Science, EarlyView.
The small brown planthopper (SBPH), Laodelphax striatellus, can trigger large‐scale outbreaks when encountering suitable habitats during migration due to their strong reproductive ability. This study investigated the role of juvenile hormone (JH) in regulating SBPH reproduction.

Stereological study of organelle distribution in human mature oocytes

open access: yesScientific Reports
The ultrastructure of human oocytes has been described only qualitatively. To offer a precise organelle spatial distribution and organelle volume during the main maturation stages, we previously conducted stereological studies on prophase-I (GV) and ...

Enhanced in vitro maturation of canine oocytes by oviduct epithelial cell co-culture.

open access: yesTheriogenology, 2018
Canine-assisted reproductive techniques have been successful for several years; however, the lack of an oocyte in vitro maturation system has limited their application.

Gonadal Development–Related Genes and a Male‐Specific Genetic Marker Identified in the Endangered Sichuan Taimen (Hucho bleekeri)

open access: yesIntegrative Zoology, EarlyView.
Integrated transcriptomic and proteomic analyses were used to validate gonadal development–related genes and to identify a sex‐specific molecular marker in Hucho bleekeri. ABSTRACT Sex determination and differentiation represent fundamental topics in reproductive biology. Sichuan taimen (Hucho bleekeri), a first‐class national protected fish species in

Biotechnological bases of the development of cloned pig embryos

open access: yesВавиловский журнал генетики и селекции, 2019
The term ‘clone’ in animal biotechnology refers to an organism derived from non-sexual reproduction, which is both a direct offspring and a genetic copy of the parent organism.
