Epigenetics and cell diversity in the embryo

A research team at the Max Planck Institute for Molecular Genetics in Berlin has explored the role of factors in embryonic development that do not alter the sequence of DNA, but only epigenetically modify its "packaging". ...

New material mimics strength, toughness of mother of pearl

In the summer, many people enjoy walks along the beach looking for seashells. Among the most prized are those that contain iridescent mother of pearl (also known as nacre) inside. But many beachcombers would be surprised ...

Overcoming genomic imprinting barrier improves mammal cloning

Somatic cell nuclear transfer (SCNT, also known as cloning) technology holds great potential in animal production and regenerative medicine. However, the extremely low efficiency and frequently observed abnormalities in cloned ...

Human embryo-like model created from human stem cells

Scientists from the University of Cambridge, in collaboration with the Hubrecht Institute in The Netherlands, have developed a new model to study an early stage of human development, using human embryonic stem cells. The ...

Why developing nerve cells can take a wrong turn

A group of scientists from CECAD has found a mechanism by which neurodevelopmental diseases concerning neurons can be explained. The loss of a certain enzyme, UBE2K, impedes the differentiation of stem cells by silencing ...
