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.

Ancient Viral DNA Plays a Key Role in Embryonic Development

More than half of the human genome is made up of thousands of remnants of ancient viral DNA, known as transposable elements, which are pervasive across the tree of life.

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.

Insights into Neurodegenerative Diseases and Pest Control

Key gene regulators that allow certain deafened animals, such as fish and lizards, to naturally regenerate their hearing have been identified by a recent USC Stem Cell study that was published in the journal Proceedings of the National Academy of Sciences (PNAS).

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).

New Understanding of the Evolution of Multicellular Life

In 2017, the single-celled species Chromosphaera perkinsii was found in maritime sediments in Hawaii. More than a billion years ago, long before the first animals appeared on Earth, the earliest indications of its existence were found.

Ancient Protist May Hold Clues to Evolution of Multicellular Life

Chromosphaera perkinsii is a single-celled species discovered in 2017 in marine sediments around Hawaii. The first signs of its presence on Earth have been dated at over a billion years, well before the appearance of the first animals.

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.

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.

Research Advances Understanding of Gene Expression Mechanisms

During embryonic development, cells start out as pluripotent, or have the potential to become many different cell types through differentiation.

Unveiling the Potential of YY1 in Blood Cell Development and Therapy

Common lymphoid progenitors, pre-pro-B cells, pro-B cells, pre-B cells, immature B cells, and finally more mature and specialized B cells are the stages in which B cells, white blood cells that produce antibodies, develop.

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.

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.
