Project description:Somatic cells surrounding the oocyte were sampled at the following stages: developmentally incompetent or poorly competent prophase I oocytes (NC1 oocytes), developmentally competent prophase I oocytes (C1 oocytes), and developmentally competent metaphase II oocytes (C2 oocytes). NC1 samples were collected from immature stage IV follicles, C1 samples from immature stage VI follicles, and C2 samples from in vitro matured stage VI follicles. Global transcriptional profiling was performed using somatic cells collected from xenopus ovarian follicles during in vivo oocyte developmental competence acquisition. Somatic cells were collected at 3 stages of oogenesis: early stage follicles (stage IV, vitellogenic, prophase I arrested oocytes, meiotically competent but developmentally incompetent, n=5), late stage follicles (stage VI, post-vitellogenic, prophase I arrested oocytes, meiotically competent and developmentally competent, n=5) and ovulatory follicles collected after in vitro maturation induction with hCG of post-vitellogenic follicles (metaphase II arrested oocytes, developmentally fully competent, n=5).

Project description:Somatic cells surrounding the oocyte were sampled at the following stages: developmentally incompetent or poorly competent prophase I oocytes (NC1 oocytes), developmentally competent prophase I oocytes (C1 oocytes), and developmentally competent metaphase II oocytes (C2 oocytes). NC1 samples were collected from late vitellogenic females (LV), C1 samples from post-vitellogenic females (PV), and C2 samples from females undergoing meiotic maturation (Germinal Vesicle Breakdown) Global transcriptional profiling was performed using somatic cells collected from rainbow trout ovarian follicles during in vivo oocyte developmental competence acquisition. Somatic cells were collected at 3 stages of oogenesis: NC1 stage follicles (LV, late vitellogenic, prophase I arrested oocytes, meiotically incompetent and developmentally incompetent, n=6), C1 stage follicles (PV, post-vitellogenic, prophase I arrested oocytes, meiotically competent and developmentally competent, n=16). Ovulatory follicles were also collected during oocyte maturation after in vivo induction (metaphase II arrested oocytes, developmentally fully competent, n=6).

Project description:Somatic cells surrounding the oocyte were sampled at the following stages: developmentally incompetent or poorly competent prophase I oocytes (NC1 oocytes), developmentally competent prophase I oocytes (C1 oocytes), and developmentally competent metaphase II oocytes (C2 oocytes). NC1 cumulus cells (CC) were sampled from immature calf oocytes, C1 samples from immature cow oocytes, and C2 samples from in vivo matured cow oocytes. Global transcriptional profiling was performed using cumulus cells collected from bovine ovarian follicles during in vivo oocyte developmental competence acquisition. Cumulus cells were collected at 3 stages: early stage follicles (prophase I arrested oocytes, meiotically competent but developmentally incompetent, n=6), late stage follicles (prophase I arrested oocytes, meiotically competent and developmentally competent, n=6) and ovulatory follicles collected by ovum pick-up (OPU) in vivo (metaphase II arrested oocytes, developmentally fully competent, n=5).

Project description:RNA-seq technology was used to identify differentially localized transcripts from Xenopus laevis and Xenopus tropicalis stage VI oocytes. Besides the discovery of a group of novel animally enriched RNAs, this study revealed a surprisingly low conservation of vegetal RNA localization between the two frog species. mRNA profiles of Xenopus laevis and Xenopus tropicalis animal and vegetal oocyte halves were generated by RNA-seq technology. For Xenopus laevis, animal and vegetal oocyte RNA preparations from two different females were generated in duplicates. For Xenopus tropicalis, animal and vegetal oocyte RNA preparations from two different females were analyzed.

Project description:Cumulus cells surrounding the oocyte were sampled at the following stages: developmentally incompetent or poorly competent prophase I oocytes (NC1 oocytes), developmentally competent prophase I oocytes (C1 oocytes), and developmentally competent metaphase II oocytes (C2 oocytes). NC1 samples were collected from immature, unexpanded cumulus-oocytes complexes (COC) from prepubertal (3-week-old) mice, C1 samples from immature, unexpanded cumulus-oocytes complexes (COC) from adult (8-week-old) and C2 samples from mature, expanded COCs obtained from the oviduct from 8-week-old mice after standard superovulation protocol. Global transcriptional profiling was performed using cumulus cells collected from murine ovarian follicles during in vivo oocyte developmental competence acquisition. Cumulus cells were collected at 3 stages: early stage follicles (prophase I arrested oocytes, meiotically competent but developmentally incompetent, n=5), late stage follicles (prophase I arrested oocytes, meiotically competent and developmentally competent, n=5) and ovulatory follicles collected in vivo (metaphase II arrested oocytes, developmentally fully competent, n=5).
