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.

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.

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.
