The young plant's pantry does more than just feed it

The endosperm, the tissue surrounding the plant embryo in the seed, has long been perceived as a nourishing tissue that is abandoned once the transition to the seedling is complete. A Swiss team, led by scientists from the ...

Stem cell model for early human embryo development

The creation of cellular structures similar to blastocysts has enabled KAUST scientists to build an in vitro model that mimics the earliest moments of human embryogenesis.

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 ...
