Embryonic Development News and Research

RSS

Embryonic development or embryogenesis is the process by which the embryo is formed and develops. It starts with the fertilization of the ovum, egg, which, after fertilization, is then called a zygote. The zygote undergoes rapid mitotic divisions, the formation of two exact genetic replicates of the original cell, with no significant growth (a process known as cleavage) and cellular differentiation, leading to development of an embryo.

Scientists uncover shared gene signatures that reveal how mammals age

Researchers mapped more than 11,000 transcriptomes across mice, rats, macaques, and humans, revealing conserved molecular signatures of aging and mortality across tissues, species, and cell types. The study developed interpretable transcriptomic clocks that track age, mortality-related molecular change, chronic disease signals and responses to lifespan-altering interventions.

UC Davis scientists identify protein key to male fertility

The causes of male infertility can be hard to diagnose, with many tests failing to detect genetic defects. Sometimes, infertility doesn't even involve the genes themselves.

Endometriosis increases risk of some birth defects in infants

Research indicates women with endometriosis may face a higher risk of congenital anomalies in infants, emphasizing the need for further investigation.

New AI framework predicts how cells make fate decisions

Scientists at the Stowers Institute for Medical Research, Helmholtz Munich, the Technical University of Munich, and the University of Oxford have developed RegVelo - a new AI framework that simultaneously models cellular dynamics and gene regulation, enabling researchers to predict, simulate, and experimentally validate how cells make fate decisions.

Scientists find that human embryos are vulnerable to COVID

A University of California, Riverside study reports that cells in the earliest stages of human development could be susceptible to infection by SARS-CoV-2, which causes COVID-19, offering new insight into how the virus interacts with developing human tissues and why that may matter for pregnancy research.

Study shows eIF4G2 gene maintains adult intestinal stem cell identity

Years before he conducted the research that would earn him a Nobel Prize in Physiology and Medicine, Shinya Yamanaka, MD, PhD, was a postdoctoral scientist at Gladstone Institutes, studying genes.

Molecular switch protein Ten4 guides neuron migration in the developing brain

During brain development, neurons can regulate their movement until they reach their final destination thanks to a "molecular switch" involving the protein Teneurin 4 (Ten4).

Scientists create large library of mitochondrial DNA mutant models

Some of your most important life partners are the mitochondria that power all your cells. You and these little cellular powerhouses are in a 1.5-billion-year-old evolutionary relationship-but mitochondria brought some baggage.

UPFs before conception may shape fertility and embryo growth

Findings show ultraprocessed food consumption before conception influences fertility and embryonic development, urging further research in this area.

Study connects ultra-processed diets to fertility and embryo development

Eating large amounts of ultra-processed food (UPF) is linked not only to reduced fertility in men, but also to slower growth in early embryos, and smaller yolk sacs, which are essential for early embryonic development, according to new research.

Scientists win awards for the discovery of genomic imprinting and tumor’s power grid

For their discovery of genomic imprinting, developmental biologists Davor Solter and Azim Surani will receive the 2026 Paul Ehrlich and Ludwig Darmstaedter Prize, endowed with €120,000, on March 14 at Frankfurt’s Paulskirche.

New imaging method maps gene activity across entire zebrafish embryo

How does a tiny cluster of cells become an embryo with a head, trunk, and tail? And how do thousands of genes coordinate this development?

Study aims to understand molecular origins of CTNNB1 neurodevelopmental syndrome

On the occasion of Rare Disease Day, the Biofisika Institute (CSIC, EHU) presents the progress of a project aimed at understanding the molecular origin of CTNNB1 neurodevelopmental syndrome, a rare disease caused by mutations in the beta-catenin protein.

Pigs and grizzly bears may reveal secrets of youthful skin

The secret to youthful appearance and repairing scars may lie in a microscopic skin structure humans share with pigs and grizzly bears - but, surprisingly, not monkeys.

Sperm RNA aging shift that may explain paternal age effects

Study reveals an 'aging cliff' in sperm RNA, linking age-related changes to early development and highlighting risks associated with advanced paternal age.

Study shows DHPS enzyme controls macrophage maturation across multiple organs

A new study led by researchers at the Johns Hopkins Kimmel Cancer Center, its Bloomberg~Kimmel Institute for Cancer Immunotherapy and the Johns Hopkins Bloomberg School of Public Health found that an enzyme involved in protein translation is essential for circulating immune cells, called monocytes, to mature into tissue-resident macrophages, a specialized population of immune cells that maintain organ health by clearing dead cells and debris.
