Multigenerational effects of abnormal folate metabolism on embryo growth and development
… spectrum of developmental phenotypes including growth defects and congenital malformations. Remarkably, the Mtrrgt mouse line is a model of transgenerational epigenetic inheritance since the congenital malformations persist at least up to four wildtype generations after an Mtrr+/gt maternal …

Factors influencing the development and mortality rate of shy and cat shark embryos in South African waters
… elasmobranch reproductive behaviour, including embryo growth and development. Two Scyliorhinid species endemic to South African waters are investigated here, Poroderma pantherinum, commonly known as the Leopard catshark and Haploblepharus pictus the Dark shyshark. Observations were made both in …

Carbohydrates in Glycine max (L.) Merr. fruits during early ontogeny
… of starch and other soluble carbohydrates in the embryos and young developing fruits of 'Essex' soybeans were determined at anthesis and continuing 10 days after flowering (DAF). The embryo was shown to be filled with starch grains which disappeared with development. Digestion of embryo sections …

Role of transcription factor Runx1 in uterine stromal cell differentiation and maternal-fetal interaction during mouse pregnancy
… including spontaneous miscarriage, intrauterine growth restriction and preeclampsia. Our study revealed that the expression of Runx1, a transcription factor belonging to the runt-domain family, is markedly elevated in the uterine stromal cells during decidualization. Conditional deletion of the …

The role of Ras-related C3 botulinum toxin substrate 1 (RAC1)-dependent pathway in the regulation of uterine function during early pregnancy
… cells, which become secretory and support the growth of the embryo before placentation. At the same time, new blood vessels begin to form in the maternal decidua from pre-existing vasculature. This process termed angiogenesis is critical for the establishment of the placenta and the maintenance …

The effect of steer serum, bovine serum albumin and uterine flushings from ovariectomized progesterone-estrogen treated cows on early bovine embryo development
… superovulated with follicle stimulating hormone. Embryos were non-surgically recovered 6 days post-mating. Ninety embryos were morphologically evaluated and placed in culture in Hams F-10 media supplemented with a 10% protein source (steer serum, bovine serum albumin, or uterine flushings). Embryo …

Gene action involved with reproduction and growth of brain and muscle in weight-selected lines of chickens
Genetic Variation influencing reproduction and growth of White Rock chickens was studied. The populations used were lines high (HH) and low (LL) selected for 56-day body weight, reciprocal F₁ crosses (HL and LH), F₂ crosses of the F₁ and dwarf populations (HD and LD) originating from lines HH and …

Morphogenesis of the early post-implantation mouse embryo
… give rise to the early post-implantation mouse embryo (egg cylinder) have not been thoroughly studied and our knowledge is restricted to “snap-shot” descriptions of embryos recovered at different stages of implantation from the mother. A central feature of the egg cylinder is the pro-amniotic …

Germination niche of Sardinian endemic species in mountain riparian deciduous forests
… subsequent plant establishment and reproductive growth. In non-dormant seeds, the germination response to accumulated temperature could be modelled by a thermal time (θ) approach; in this model, seeds accumulate units of thermal time (°Cd) to germinate for a percentile g of the population. When …

Human oocytes and embryos viewed by time-lapse videography, and the development of an embryo deselection model
… due to inaccuracy in selecting the best quality embryo(s) from the cohort for transfer. Novel methodologies for improved selection are being developed, and time-lapse observation of human embryos is gaining increasing popularity due to the more detailed morphokinetic information obtained plus …

A study of incompatibility within the genus Zantedeschia : a thesis presented in partial fulfilment of the requirements for the degree of Master of Horticultural Science at Massey University, Palmerston North, New Zealand
… incompatibility by examining pollen physiology, embryogenesis of compatible and incompatible crosses, and rescue of embryos from incompatible crosses using embryo culture techniques. Zaethio pica 'Childsiana' pollen was similar in morphology to pollen from the coloured species of Section II. …

The Role of Nogo-A During Development of the Chick Central Nervous System
… about the putative functions of Nogo-A during embryonic development. To examine its potential role we isolated and analyzed the Nogo-A sequence in the chick, we localized its mRNA expression pattern and cell-specific distribution during key phases of cortical development, and studied regulation …
