Recapitulating early stages of the human body plan in a dish

Although Michelangelo's masterpiece David captured the magnificence of the human body - how this exquisite body plan is exactly established during human development has puzzled scientists for more than a century.

Study identifies genetic variation linked with posterior urethral valves in males

Genetic variation affecting developmental genes not previously linked to urethral development may contribute to a congenital condition that is the most common cause of kidney failure in young males, a study published today in eLife suggests.

Discoveries about embryonic blood stem cell creation may solve donor blood stem cell shortages

Making stem cells from a patient’s adult cells – rather than human embryos – is one of the holy grails in modern medicine treatments. New research brings us two steps closer.

KU Leuven scientists create a new type of human cell in the lab using stem cells

Professor Vincent Pasque and his team at KU Leuven have managed to generate a new type of human cell in the lab using stem cells. The new cells closely resemble their natural counterparts in early human embryos.

Circuits of touch and sight are intermingled in the embryo, study shows

In embryonic stages, tactile stimuli simultaneously activate tactile and visual neural pathways. Shortly after birth, both pathways reorganize to allow separate processing of touch and vision.

Study determines the reason behind the failure of IVF embryos

In humans, a fertilized egg is no guarantee of reproductive success. Most embryos stop developing and perish within days of fertilization, usually because they have an abnormal number of chromosomes. Now, researchers at Columbia University Vagelos College of Physicians and Surgeons have found that most of these mistakes are due to spontaneous errors in DNA replication in the earliest phase of cell division.

"Selfish chromosomes" explain why most human embryos die very early on, study suggests

New research by a scientist at the Milner Center for Evolution at the University of Bath suggests that "selfish chromosomes" explain why most human embryos die very early on. The study, published in PLoS, Biology, explaining why fish embryos are fine but sadly humans' embryos often don't survive, has implications for the treatment of infertility.

Study provides a crucial reference for fetal tissue generation in the lab

Scientists have identified the biochemical signals that control the emergence of the body pattern in the primate embryo.

Study identifies a gene that plays an important role in embryo development

A new study co-led by a Cedars-Sinai investigator identified a gene that plays an important role in a biological pathway involved in embryo development.

Regulation of alternative splicing goes haywire in cells of a newly formed embryo

Alternative splicing is a fundamental biological process that allows cells to make many different types of mRNAs and proteins from a limited number of genes. For many animals, including humans, it is a feature that is essential for the development of complex cells such as muscles or neurons.

Predicting the risk of some common diseases in preimplantation fertilized embryos

A new study uses a novel strategy for whole-genome reconstruction by using parental genome sequencing and sibling embryo genotyping.

Experts highlight understated ethics, unclear utility of polygenic embryo testing

New technologies are expanding the reach and accessibility of preimplantation genetic testing of human embryos. But what these advances can deliver is still unclear, and a frank assessment of their profound ethical implications is urgently needed, concludes a commentary in Nature Medicine.

New stem cell model could help map out the key genomic changes during early development

Researchers from the Babraham Institute have today published their latest work in the journal Cell Stem Cell describing a new subset of human embryonic stem cells that closely resemble the cells present at the genomic 'wake up call' of the 8-cell embryo stage in humans.

Researchers develop 3D human spinal cord implants for treating paralyzed patients

For the first time in the world, researchers from Sagol Center for Regenerative Biotechnology at Tel Aviv University have engineered 3D human spinal cord tissues and implanted them in lab model with long-term chronic paralysis.

‘Lefty’ protein pumps the brakes during initial stages of embryo differentiation

A protein known as Lefty pumps the brakes as human embryos begin to differentiate into the bones, soft tissues and organs that make us.

Research offers a phylogenetic and ontogenetic overview of the primitive streak

In their publication in Science, Professor Guojun Sheng (Kumamoto University, Japan), Professor Alfonso Martinez Arias (Universidad Pompeu Fabra, Spain) and Professor Ann Sutherland (University of Virginia Health System, USA) offer a phylogenetic and ontogenetic overview of the primitive streak and its role in mediating amniote (vertebrate animals that develop on land) gastrulation, and discuss the implications of embryonic stem cell-based models of early mammalian embryogenesis on the function of this structure.
