DNA gene chips and novel software used to describe kidney development
The step-by-step development of a mammalian kidney, from its early beginnings in the embryo to its adult role as a vital filtration system, has been described by UCSD School of Medicine researchers

Cloned stem cells prove identical to fertilized stem cells
Scientists generally agree that all cloned animals are biologically flawed. But they don't agree about what that means for stem cells derived from cloned embryos, the basis for therapeutic cloning.

Genetic interplay between the transcription factors Sp8 and Emx2 in the patterning of the forebrain
The authors show that the transcription factor Sp8 has an essential role in the molecular and functional patterning of the developing telencephalon along the anteroposterior axis by modulating the expression gradients of Emx2 and Pax6.

Most embryos produced during IVF do not result in live births
Researchers have found that 85 percent of embryos transferred during in vitro fertilization fail to become live births.

Reseachers find evidence that prenatal use of ecstasy can cause long-term memory loss and other impairments in offspring
Researchers today reported the first evidence that a mother’s use of MDMA (ecstasy) during pregnancy may result in specific types of long-term learning and memory impairments in her offspring.

UCSD Biologists Discover Chemical Important In Guiding Visual System Development
Neurobiologists have discovered a chemical responsible for the bursts of electrical activity in the brain that guide the development of the visual system

Study Shows Ingredient Commonly Found In Shampoos May Inhibit Brain Development
An ingredient found in many shampoos and other personal care products appears to interfere with normal brain development in baby mice when applied to the skin of pregnant mice,

Ovarian stimulation in mice adversely affects embryo development and implantation
They found an adverse effect of superovulation on embryo quality.

A role for rhoB in the delamination of neural crest cells from the dorsal neural tube
In this study, the authors attempted to identify additional
molecules that might participate in the early steps of neural
crest differentiation.

Tracking mesoderm induction and its specification to the hemangioblast during embryonic stem cell differentiation
The authors have established a model system with which to study the development of mesoderm and its specification to the hematopoietic and vascular lineages after ES cell differentiation in culture.

Embryonic Stem Cells: Prospects for Developmental Biology and Cell Therapy
This review focuses both on mouse and human ES cells with respect to in vitro propagation and differentiation as well as their use in basic cell and developmental biology and toxicology...

Embryonic stem cell differentiation: emergence of a new era in biology and medicine
Recent advances in our understanding of ES cell differentiation have provided new insights essential for establishing ES cell-based developmental models and for the generation of clinically relevant populations for cell therapy.

Early stages of neural crest ontogeny: formation and regulation of cell delamination
A summary of recent advances in the early stages of crest ontogeny that comprise specification of epithelial progenitors to a neural crest fate and the onset of neural crest migration.

In early embryos, cilia get the message across
Having your heart in the right place usually means having it located on the left side of your body.

Are IVF embryos starved of a vital ingredient?
The lack of natural growth factors in the fluid in which IVF embryos are grown could have lifelong effects on people conceived this way.

Many couples choose to donate surplus embryos for stem cell research
Nearly 50% of couples who were interviewed at least 3 years after undergoing in vitro fertilization chose to donate their surplus, stored embryos for stem cell research

The ultimate spa: embryonic body wash controls left-right development
Humans and other animals may appear to be symmetrical on the outside, but symmetry is only skin deep.

Researchers model embryo implantation and tumour metastasis in fruit flies
A research team discovered that a protein previously linked to mammalian embryo implantation, as well as tumour metastasis, plays similar roles in fruit fly development

Jefferson researchers uncover biochemical clues to how cells migrate in embryos
The work offers potential insights into disease processes, including cancer

Who laid the first egg? An update
Scientists move a step closer to linking embryos of earth's first animals and their adult form
