The recipe for making a fruit fly

Scientists use mass spectrometry to determine the absolute copy number of nuclear proteins and histone marks

21-Oct-2019

Currently, most if not all of the proteins that are required for constructing a multicellular organism are known. However, it is largely unclear how many copies of each protein species are present and needed to permit an animal to develop into a complete organism. Researchers at the Max Planck ...

Unraveling a genetic network linked to autism

06-Nov-2018

Donnelly Centre researchers have uncovered a genetic network linked to autism. The findings will facilitate developing new therapies for this common neurological disorder. As part of a collaborative research program focusing on autism led by Benjamin Blencowe, a professor in the University of ...

3D analysis of retinal tissue shows how to keep shape during organ growth

20-Aug-2018

During the early development of an embryo, many tissues and organs already form their final shape. This shape has to be maintained while the organism keeps growing. As the correct shape of a tissue is often essential for its proper function, it is crucial to understand how it remains unchanged ...

Evolving genetic barcodes show origin of cells in vivo

13-Aug-2018

All humans begin life as a single cell that divides repeatedly to form two, then four, then eight cells, all the way up to the ~26 billion cells that make up a newborn. Tracing how and when those 26 billion cells arise from one zygote is the grand challenge of developmental biology, a field that ...

How molecules measure embryo size

03-Aug-2018

Early during their development, embryos can fully compensate for tissue loss: If large parts are removed, the embryos still develop into smaller but complete and healthy organisms. Researchers at the Friedrich Miescher Laboratory of the Max Planck Society in Tübingen wanted to elucidate the ...

A protein that promotes compatibility between chromosomes after fertilization

26-Jul-2018

A research team from the Center for Biomedical Research (CBMR), at the University of Algarve (UAlg), and Instituto Gulbenkian de Ciência (IGC), led by Rui Gonçalo Martinho (UAlg) and Paulo Navarro-Costa (UAlg and IGC) has identified the mechanism by which the fertilized egg balances out the ...

Switch discovered to convert blood vessels to blood stem cells in embryonic development

20-Mar-2018

A switch has been discovered that instructs blood vessel cells to become blood stem cells during embryonic development in mice. Using single-cell technology, researchers from the Wellcome Sanger Institute in Cambridge and the European Molecular Biology Laboratory in Rome discovered that two sets ...

How Blood Vessels Are Formed

New insights into the development of the vascular system

18-Sep-2017

New insights into the development of the vascular system: researchers in the team of Dr Carmen Ruiz de Almodóvar of the Heidelberg University Biochemistry Center have discovered a crucial biological step that regulates the formation of blood vessels. They were able to show that the proteins YAP ...

Early gene-editing success holds promise for preventing inherited diseases

03-Aug-2017

Scientists have, for the first time, corrected a disease-causing mutation in early stage human embryos with gene editing. The technique, which uses the CRISPR-Cas9 system, corrected the mutation for a heart condition at the earliest stage of embryonic development so that the defect would not be ...

Understanding the architecture of our 'second brain'

22-May-2017

Scientists have made an important step in understanding the organisation of nerve cells embedded within the gut that control its function -- a discovery that could give insight into the origin of common gastrointestinal diseases, including irritable bowel syndrome and chronic constipation. The ...
