Regeneration of the radial nerve cord in the sea cucumber Holothuria glaberrima
Regeneration of neurons and fibers in the mammalian spinal cord has not been plausible, even though extensive studies have been made to understand the restrictive factors involved.

Inhibition of HMG CoA reductase reveals an unexpected role for cholesterol during PGC migration in the mouse
Primordial germ cells (PGCs) are the embryonic precursors of the sperm and eggs.

Most Clones Doomed From The Start, According To Temple University Embryologist
Until scientists can improve the early development of cloned embryos, cloning will remain marginally successful

Inactive Genes May Contribute To Failure Of Animals Cloned From Adult Cells, Study Finds
Only 1 percent to 3 percent of animals cloned from adult cells survive to birth; many die mysteriously very early in development, around the time of implantation.

Adult Mouse Bone Marrow Stem Cells Can Become Cells Of The Nervous System
University of Minnesota researchers show that adult bone marrow stem cells can be induced to differentiate into cells of the midbrain.

Stem Cells From Monkey Teeth Can Stimulate Growth And Generation Of Brain Cells
Researchers at the Yerkes National Primate Research Center, Emory University, have discovered dental pulp stem cells can stimulate growth and generation of several types of neural cells.

Foxd3 Gene Allows Stem Cells To Remain Stem Cells
In the search to understand the nature of stem cells, researchers at the University of Pennsylvania School of Medicine have identified a regulatory gene that is crucial in maintaining a stem cell's ability to self-renew.

Knocking The Sox Off Early Mammalian Development; Scientists Find Key Embryonic Stem Cell Gene
Scientists have identified a gene that is required during early mammalian embryogenesis to maintain cellular pluripotency – the ability of an embryonic cell to develop into virtually any cell type of the adult animal.

Developing Fruit Fly Embryo Is Capable Of Genetic Corrections
Animals have an astonishing ability to develop reliably in spite of variable conditions during embryogenesis. New research

New gene may offer clues to infertility in both cows and women
A newly identified gene that controls embryo development in cows may someday offer clues into the cause of infertility in women.

Toothed Embryo Of Mammoth
For the first time, a well-preserved lower jawbone of a mammoth embryo is found by paleontologist E.N. Mashchenko and his colleagues in the Tomsk area.

How do you know whether you are male or female?
New research published online this week in the open-access journal PLoS Biology investigates this basic and much-studied question in the fruit fly, and comes to a surprising new conclusion.

Protein Kinase D regulates several aspects of development in Drosophila melanogaster
Protein Kinase D (PKD) is an effector of diacylglycerol-regulated signaling pathways.

Clam embryo study shows pollutant mixture adversely affects nerve cell development
Demonstrating that clam embryos are affected by BCE paves the way for additional studies that may help explain how exposure to BCE affects human nerve cell

Changes to embryos can elicit change in adult fish
In a study illustrating the apparent linkages between the evolutionary development and embryonic development of species

Molecule that restricts mouse cells' potency could yield embryonic stem cells without the sacrifice of embryos
Scientists at the University of Pennsylvania have identified a receptor that plays a key role in restricting embryonic stem cells’ pluripotency

Scientists' transgenic chicken aids embryo research
Currently, the chick embryo is often used as a model to understand normal and abnormal embryo development.

Long-term effects of embryo culture on behavior studied
In a test that measures anxiety, male mice developed from cultured embryos spent more time in open spaces

Technique makes it easier to see mouse embryo in all its glory
A fast, high-resolution, 3D mouse embryo visualization technique developed by collaborators

Patterning the early Xenopus embryo
This review revisits these early stages of Xenopus development and summarizes the recent explosion of information on the intrinsic and extrinsic factors that are responsible for the first phases of embryonic patterning.
