Scientists identify essential factors for limb formation

Scientists at the Centro Nacional de Investigaciones Cardiovasculares (CNIC), working in partnership with researchers at the Institut de Recherches Cliniques de Montréal (IRCM) in Canada, have identified Meis transcription ...

Scientists create model of an early human embryo from skin cells

In a discovery that will revolutionize research into the causes of early miscarriage, infertility and the study of early human development—an international team of scientists led by Monash University in Melbourne, Australia ...

How an embryo tells time

It is estimated that the majority of pregnancies that fail do so within the first seven days after fertilization, before the embryo implants into the uterus. In this time period, a complicated cascade of events occurs with ...

Organoids produce embryonic heart

There was a time when the idea of growing organs in the lab was the stuff of science fiction. Today, stem cell biology and tissue engineering are turning fiction into reality with the advent of organoids: tiny lab-grown tissues ...

Embryos taking shape via buckling

The embryo of an animal first looks like a hollow sphere. Invaginations then appear at different stages of development, which will give rise to the body's structures (the brain, digestive tract, etc.). According to a hypothesis ...

Origin of a complex life form revealed

Researchers from McGill University have revealed the steps by which two very distinct organisms—bacteria and carpenter ants—have come to depend on one another for survival to become a single complex life form. The study, ...

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". ...
