Embryogenesis in Arabidopsis thaliana: Mutant library construction and embryo mutant identification and characterization
Biological sciences Arabidopsis thaliana Embryogenesis Mutant RSH
2015/1/28
Embryogenesis plays a central role in the plant life cycle. It starts after fertilization. A single zygote divides asymmetrically, giving rise a small apical cell and a larger basal cell. The small ap...
Follicle Stimulating Hormone (FSH) Dosage Based on Body Weight Enhances Ovulatory Responses and Subsequent Embryo Production in Goats
Superovulation pFSH Dosage Body Weight Goat
2016/5/17
An experiment was conducted to evaluate the efficacy of porcine follicle stimulating hormone (pFSH) dosage based on body weight (BW) on ovarian responses of crossbred does. Thirty donor does were divi...
Maternal Effects of Japanese Shorthorn Cows on the Growth of Embryo-transferred Japanese Black Calves in a Cow-calf Grazing System
Japanese Shorthorn Japanese Black Cattle Embryo Transfer Cow-calf Grazing
2016/5/12
The growth performance of embryo-transferred Japanese Black calves that were born from, and suckled by, Japanese Shorthorn cows in a cow-calf grazing system (BS-group, n = 5) was compared to that of J...
Ovarian Follicular Dynamics, Ovarian Follicular Growth, Oocyte Yield, In vitro Embryo Production and Repeated Oocyte Pick Up in Thai Native Heifers Undergoing Superstimulation
FSH Follicle OPU COCs IVP Cattle
2016/5/11
The objective of this study was to compare the effectiveness of the protocols for superstimulation of follicular growth in Thai native heifers. Heifers (n = 20) were randomly divided into four groups ...
Differential Embryo Development among Tibetan Chicken, DRW and Shouguang Chicken Exposed to Chronic Hypoxia
Adaptation Chronic Hypoxia Developmental Physiology Tibetan Chicken
2016/4/29
Avian embryos at high altitude are independent of maternal protection against hypoxia, which is contrary to mammals. It is well known that chronic hypoxic exposure at key points can significantly impa...
Stage-specific Expression of Lanosterol 14-Demethylase in Mouse Oocytes in Relation to Fertilization and Embryo Development Competence
Mouse Oocyte Lanosterol 14 -Demethylase In vitro Fertilization Early Embryo Development
2016/4/29
Follicular fluid meiosis-activating sterol (FF-MAS) has been suggested as a positive factor which could improve the oocyte quality and subsequent embryo development after in vitro fertilization. Howev...
Lmbr1 Expression in Early Embryo Development Stages in White Leghorn and Chinese Silky
Polydactyly Lmbr1 Embryo Development White Leghorn Chinese Silky
2016/4/28
Lmbr1 is regarded as a key gene that controls the digital model formation in early developmental stages of the chicken. However, there are few reports of lmbr1 expression levels and tendencies in 4-to...

Bovine Oviduct Epithelial Cell Bovine IVM/IVF Embryos Growth Factor Gene Apoptosis Gene Antioxidant Gene
2016/4/28
The objective of this study was to investigate the effects of cell status of BOEC on development of bovine IVM/IVF embryos and gene expression in BOEC before or after culturing of embryos. The develop...
一种早期胚胎体外培养新方法的建立Establishment of a New Method for Early Embryo Culture in vitro
体外培养 套皿法 早期胚胎
2008/1/8
摘要
建立一种不依赖于液体石蜡的早期胚胎体外培养方法——套皿法，并比较了4种不同处理方法体外培养胚胎的效果。结果显示，采用套皿法进行胚胎培养，盖液体石蜡和不盖液体石蜡皿中的胚胎在各阶段的发育率差异不显著。与套皿法相比，用单皿微滴覆盖法(Brinster法)培养的胚胎在各阶段的发育率显著降低。不覆盖液体石蜡单皿中的胚胎则阻断于二细胞阶段。本实验设计的套皿法是一种有效的早期胚胎体外培养方法，为早期...
