The role of spatial averaging in the precision of gene expression patterns [PDF]

, 2009
During embryonic development, differentiating cells respond via gene expression to positional cues from morphogen gradients. While gene expression is often highly erratic, embryonic development is precise. We show by theory and simulations that diffusion

Magnesium and embryonic development [PDF]

Magnesium Research, 2014
Important for energy metabolism, neurotransmission, bone stability, and other cellular functions, Mg(2+) has well-established and undisputedly critical roles in adult tissues. Its contributions to early embryonic development are less clearly understood.

Single-cell RNA sequencing identifies distinct mouse medial ganglionic eminence cell types. [PDF]

, 2017
Many subtypes of cortical interneurons (CINs) are found in adult mouse cortices, but the mechanism generating their diversity remains elusive. We performed single-cell RNA sequencing on the mouse embryonic medial ganglionic eminence (MGE), the major ...

Transcription factor OTX2 silences the expression of cleavage embryo genes and transposable elements

The Journal of Reproduction and Development, 2021
Upon mammalian fertilization, zygotic genome activation (ZGA) and activation of transposable elements (TEs) occur in early embryos to establish totipotency and support embryogenesis.

A viable mouse model of factor X deficiency provides evidence for maternal transfer of factor X. [PDF]

, 2008
BackgroundActivated factor X (FXa) is a vitamin K-dependent serine protease that plays a pivotal role in blood coagulation by converting prothrombin to thrombin. There are no reports of humans with complete deficiency of FX, and knockout of murine F10 is

Alpha-2-macroglobulin is involved in the occurrence of early-onset pre-eclampsia via its negative impact on uterine spiral artery remodeling and placental angiogenesis

BMC Medicine, 2023
Background Pre-eclampsia (PE) is one of the leading causes of maternal and fetal morbidity/mortality during pregnancy, and alpha-2-macroglobulin (A2M) is associated with inflammatory signaling; however, the pathophysiological mechanism by which A2M is ...

ID3 mediates BMP2-induced downregulation of ICAM1 expression in human endometiral stromal cells and decidual cells

Frontiers in Cell and Developmental Biology, 2023
Recurrent pregnancy loss (RPL) remains an unsolved problem in obstetrics and gynecology, and up to 50% of RPL cases are unexplained. Unexplained RPL (uRPL) is widely considered to be related to an aberrant endometrial microenvironment.

Genomic instability in individuals with sex determination defects and germ cell cancer

Cell Death Discovery, 2023
The ability to transmit genetic information through generations depends on the preservation of genome integrity. Genetic abnormalities affect cell differentiation, causing tissue specification defects and cancer.

Utilizing Playdoh in the Classroom to Construct a 3D Model Depicting Cellular Movements and Tissue Remodeling during Human Gastrulation, Early Organogenesis, and Embryonic Folding

Journal of Microbiology & Biology Education, 2021
In classroom studies of mammalian embryology, students must fully grasp the cellular and tissue remodeling needed to initiate gastrulation to ensure comprehension of forthcoming developmental processes such as tissue specification and organogenesis ...
