Unveiling Human Stem Cell Model with Functional Notochord

For the first time, the notochord a tissue in the developing embryo that serves as a navigation system, telling cells where to build the spine and nervous system (the trunk) has been included in human stem cell models created by researchers at the Francis Crick Institute.

New Genetic Insights into Craniofacial Defects and Embryonic Development

An international team of researchers has identified a key genetic mechanism that regulates the formation and migration of cranial neural crest cells, which are essential for developing facial structures.

The Mechanics Behind Crocodile Morphology: A Breakthrough in Evolutionary Biology

How do humans account for the variety of morphologies found in living things? Genetics is usually the first explanation that comes to mind, but it is not the only one.

Plymouth Sound National Marine Park Launches Inspiring Rays Project to Connect Communities with Marine Life

Plymouth Sound National Marine Park – the first of its kind in the UK – has launched a groundbreaking initiative to connect communities with the rich marine life of Plymouth Sound and support the restoration of nature within the Park.

Enterococcus Co-Infection Increases Protective Slime in Pathogenic E. coli

A new study finds that two subtypes of pathogenic Escherichia coli (E. coli) produce five to 16 times more protective capsular "slime" when Enterococcus faecalis (EF) is present.

Hormonal Control of Caste Determination in Ants

Most ants have two morphologically differentiated adult castes - queens and workers - each irreversibly specialized for either reproduction or nonreproductive altruism such as foraging, defense and care of maternal brood. Adult gynes (virgin queens) normally have higher body mass, wings and frontal eyes, as well as enlarged ovaries and a sperm storage organ.

Human Cell Atlas Consortium Makes Major Progress in Understanding the Human Body

Researchers with the global Human Cell Atlas (HCA) consortium report significant progress in their quest for a better understanding of the cells of the human body in health and disease, with the publication today (20 November) of a Collection of more than 40 peer-reviewed papers in Nature and other Nature Portfolio journals.

Novel Mechanism Revealed for Zygotic Genome Activation in Drosophila

Early development of an embryo is solely supported by maternally deposited RNAs and proteins until its own genome is activated through a process called zygotic genome activation (ZGA).

The Role of Neural Crest Stem Cells in Cellular Reprogramming

Researchers at the University of Toronto have identified that neural crest stem cells, a group of cells located in the skin and other parts of the body, are the origin of reprogrammed neurons previously discovered by other scientists.

Unraveling the Spatial Complexity of Gene Expression with Seq-Scope

A new method, developed by University of Michigan researchers, creates images that are worth many gigabytes of data, which could revolutionize the way biologists study gene expression. Seq-Scope, developed by Jun Hee Lee, Ph.D., Hyun Min Kang, Ph.D., and their colleagues, was first described in Cell in 2021 as the first method to analyze gene expression at sub micrometer-scale spatial resolution.

Zebrahub Offers Unprecedented Insight into Embryonic Development

When early cartographers undertook perilous expeditions to map unknown corners of the world with sextants, compasses, and hand-drawn diagrams, it's unlikely they imagined that someday anyone with an internet connection would have access to a seamless view of the entire planet from the comfort of their own home.

Transposable Elements Drive a Critical Transition in Early Embryogenesis

Researchers at Sinai Health have discovered that DNA elements known as transposons, which may travel throughout the genome, control a crucial stage in early human development instead of human genes.

Transposable Elements Are Key to Normal Progression of Embryonic Cells

A critical transition in early human development is regulated not by our own genes, but by DNA elements called transposons that can move around the genome, Sinai Health researchers have found.

Scientists Uncover the Hidden Order in Chaotic Embryonic Development

Pipetting liquids into tiny test tubes, analyzing huge datasets, poring over research publications-;all these tasks are part of being a scientist.

Cell Division Variability Promotes Healthy Embryo Development

There is variability in when and how cells divide during the development of embryos. While researchers traditionally believed this variability was an obstacle that needed to be regulated, the Hiiragi group now found that it actually promotes healthy development.

Engineering Tissue Domains with a Synthetic Biology Approach

Researchers at Nano Life Science Institute (WPI-NanoLSI), Kanazawa University, demonstrate how morphogens combined with cell adhesion can generate tissue domains with a sharp boundary in an in vitro model system.

Human Cells Exhibit Dormant State Similar to Embryonic Diapause

In some mammals, the timing of the normally continuous embryonic development can be altered to improve the chances of survival for both the embryo and the mother.

Stem Cell Study Reveals Developmental Dance Behind Individual Variation

Researchers at the Johns Hopkins University School of Medicine have conducted a comprehensive analysis of the variations present in human stem cells. This study sheds light on how the unique “developmental dance” at the molecular level within an individual's cells can shape the formation of the brain and the body.

Epigenetic Switch Found to Activate Genes in Embryos

Researchers led by the Institute of Molecular Biology have found that 5-formylcytosine (5fC), a DNA alteration, acts as an activating epigenetic switch to activate genes during the early stages of embryonic development.
