Yolk syncytial layer formation is a failure of cytokinesis mediated by Rock1 function in the early zebrafish embryo

open access: yesBiology Open, 2012
Summary The yolk syncytial layer (YSL) performs multiple critical roles during zebrafish development. However, little is known about the cellular and molecular mechanisms that underlie the formation of this important extraembryonic structure.

The Chicken Embryo: An Alternative Animal Model in Development, Disease and Pharmacological Treatment. [PDF]

open access: yesPharmacol Res Perspect
ABSTRACT To examine various medications and substances, in vivo models such as rats and mice are routinely used. However, it is utterly desirable to reduce extensive amounts of animals for these experimental models, which are costly and time‐consuming.

Integrin-Dependent Apposition of Drosophila Extraembryonic Membranes Promotes Morphogenesis and Prevents Anoikis [PDF]

open access: yesCurrent Biology, 2004
Two extraembryonic tissues form early in Drosophila development. One, the amnioserosa, has been implicated in the morphogenetic processes of germ band retraction and dorsal closure. The developmental role of the other, the yolk sac, is obscure.By using live-imaging techniques, we report intimate interactions between the amnioserosa and the yolk sac ...

Development of the Human Placenta and Fetal Heart: Synergic or Independent?

open access: yesFrontiers in Physiology, 2018
The placenta is the largest fetal organ, and toward the end of pregnancy the umbilical circulation receives at least 40% of the biventricular cardiac output.

Targeted Deletion in the Basal Body Protein Talpid3 Leads to Loss of Primary Cilia in Embryonic Stem Cells and Defective Lineage-Specific Differentiation

open access: yesCells
Talpid3 is a basal body protein required for the formation of primary cilia, an organelle involved in signal transduction. Here, we asked if Talpid3 has a role in the regulation of differentiation and/or self-renewal of ES cells and whether cells lacking

Gastrula‐Premarked Posterior Enhancer Primes Posterior Tissue Development Through Cross‐Talk with TGF‐β Signaling Pathway

open access: yesAdvanced Science, EarlyView.
A gastrula‐premarked enhancer within the first intron of Cdx2 governs posterior embryonic development via both regulating Cdx2 expression in cis and coordinating TGF‐β signaling in trans to ensure proper posterior body development. Functional rescue in gastruloids reveals a Cdx2‐independent pathway, highlighting p‐Enh‐eRNA as key epigenetic ...

Spatiotemporal Expression of Pregnancy-Specific Glycoprotein Gene rnCGMl in Rat Placenta [PDF]

open access: yes, 1993
As a basis towards a better understanding of the role of the pregnancy-specific glycoprotein (PSG) family in the maintenance of pregnancy, detailed investigations are described on the expression of a recently identified rat PSG gene (rnCGM1) at the mRNA ...
