mRNA Dynamics Guide Cell Identity Formation

New research from Hebrew University sheds light on the regulation of mRNA during the development of the embryo. The research separates newly-transcribed from pre-existing mRNA in zebrafish embryos using a combination of single-cell RNA-Seq and metabolic labeling.

Nutrient Deprivation Induces Embryonic Diapause in Hungry Mouse Mums

It's challenging to sustain a pregnancy when food is short, or conditions are otherwise tough. That's why many mammalian embryos can postpone their growth to get through periods of environmental stress and then re-enter development when conditions improve.

Embryonic Cells Pressed into Organizers: Mechanism Unveiled

A collaboration between research groups at the University of California, TU Dresden in Germany and Cedars-Sinai Guerin Children's in Los Angeles has identified a mechanism by which embryonic cells organize themselves to send signals to surrounding cells, telling them where to go and what to do.

Groundbreaking Physics Study Offers Insights Into Self-Organization of Biological Particles

Erin McCarthy '23, physics summa cum laude, is a rarity among young scientists. As an undergraduate researcher in Syracuse University's College of Arts & Sciences' Department of Physics, she guided a study that appeared in March 2024 in Physical Review Letters. It is the most-cited physics letters journal and the eighth-most cited journal in science overall.

Researchers Identify Proteins to Reprogram Fibroblasts into Limb Progenitor Cells

In a collaborative study, researchers from Kyushu University and Harvard Medical School have identified proteins that can turn or "reprogram" fibroblasts -; the most commonly found cells in skin and connective tissue -; into cells with similar properties to limb progenitor cells.

New ACMG Statement Urges Caution with Polygenic Risk Score Testing in Embryo Selection

Should we be using polygenic risk score assessment for embryo selection? Providing in-depth analysis, the Social, Ethical and Legal Issues Committee of the American College of Medical Genetics and Genomics (ACMG) has released a new Points to Consider statement to assist healthcare professionals and patients in understanding the safety and utility of preimplantation genetic testing for polygenic disorders (PGT-P) as a clinical service.

How 3D DNA Architecture Shapes Cell Fate in Early Embryos

The intricate process of duplicating genetic information, referred to as DNA replication, lies at the heart of the transmission of life from one cell to another and from one organism to the next. This happens by not just simply copying the genetic information; a well-orchestrated sequence of molecular events has to happen at the right time.

Mathematical Models and Biological Dynamics in Embryo Development

One of life’s enduring fundamental questions revolves around the process of development. Consider human growth—how do cells autonomously arrange themselves into structures like skin, muscles, or bones? How do they coalesce to form intricate organs such as the brain, fingers, or spine?
