Oogenesis and germinal bed morphology of the brown anole (A. sagrei)

Developmental Dynamics, EarlyView.
Abstract Background The brown anole is a model species of the genus Anolis, a squamate (encompassing lizards and snakes) group widely studied in evolutionary, behavioral, and developmental biology. Full genome annotation, the establishment of gene editing techniques, and comprehensive description of reproductive tract morphology and embryogenesis in ...

Application of Conductivity Combined with Various Other Instrumental Analyses in the Detection of the Freshness and Yolk-to-White Ratio of Liquid Egg [PDF]

Shipin Kexue
This study established a rapid and efficient technique to detect the freshness and yolk-to-white ratio of liquid egg based on conductivity combined with salinity, total dissolved solids (TDS), pH, and color parameters. The results showed that during the

Mosaic activation of the zebrafish hsp70l heat shock promoter: Implications for interpreting transgenes

Developmental Dynamics, EarlyView.
Abstract Background The promoters and enhancers of heat shock genes, such as the 1.5‐kb promoter of the zebrafish hsp70l gene, are valuable tools for temporal activation of transgenes. It has been widely purported that heat shock treatments result in ubiquitous expression of hsp70l‐driven transgenes.

Use of Powdered Egg Yolk vs Fresh Egg Yolk for the Cryopreservation of Ovine Semen

Reproduction in Domestic Animals, 2004
ContentsEgg yolk is a common additive to sperm cryopreservation diluents. Because of its animal origin, however, it also represents a potential risk of microbiological contamination in the diluent. This potential contamination can be avoided by using powdered egg yolk, instead of fresh egg yolk, as it is pasteurized.

An accessible microfluidic perfusion platform for time‐restricted control of zebrafish embryonic patterning

Developmental Dynamics, EarlyView.
Abstract Understanding the dynamic nature of developmental networks requires live imaging techniques capable of capturing real‐time developmental processes in wild‐type and mutant embryos as they are exposed to pharmacological perturbations. A peculiar developmental patterning process in early vertebrate embryos is the sequential segmentation of ...

Zebrafish ventral gastrula fate map reveals neural crest progenitor domain

Developmental Dynamics, EarlyView.
Abstract Background Fate maps relate progenitor cell positions to later fates and locations of their progeny, revealing early embryonic organization. Previous zebrafish fate maps identified the origin of germ layers and derivative cell fates, but ventral gastrula progenitor domains were not fully resolved. In particular, the neural crest, a multipotent

A Comparison of Egg Yolk-Sodium Citrate, Egg Yolk-Sodium Citrate-Glycine, and Egg Yolk-Glycine as Semen Diluters

Journal of Dairy Science, 1958
Summary The average length of time that a +3 motility was maintained in egg yolk-citrate-glycine, egg yolk-glycine, and egg yolk-citrate, was 14.7, 13.9, and 6.8 days, respectively, for bovine sperm; 6.8, 8.8, and 3.5 days, respectively, for buffalo sperm; and 17.2, 8.0, and 4.4 days for ram sperm.

MIT/TFE family transcription factors, Mitf and Tfec, redundantly promote pigment cell differentiation and retinal epithelium pigmentation in teleosts

Developmental Dynamics, EarlyView.
Abstract Background Transcription factors of the MIT/TFE family—mitfa, mitfb, and tfec—play essential roles in specifying pigment cells derived from neural crest cells in vertebrates. In teleosts, which possess multiple pigment cell types, these factors exhibit partially redundant but largely distinct functions across different pigment lineages.

The Egg Yolk Surface in Fresh Eggs

Poultry Science, 1936
Abstract YOLK index is used experimentally to a considerable extent as a measure of the interior quality or past history of eggs since it appears to be more sensitive and shifts earlier during deterioration than the percentage of firm white. However yolk indexes do not evaluate the nature of the surface of the yolk—a surface that is important to the ...
