Bovine embryos as a model for early human development

The mechanisms that underlie early embryonic development in humans and cattle are very similar. Therefore, LMU researchers argue that bovine embryos might well be a better model for early human development than the mouse ...

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 ...

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 ...

Tracking life's first step: Two molecules 'awaken' brand new genome

Within hours after fertilization, a unique genome forms from chromosomes contributed by the egg and sperm. However, this new genome is initially inactive and must be "awakened" to begin the transcription of its DNA and start ...

For different species, different functions for embryonic microRNAs

(PhysOrg.com) -- When evolution has lucked into efficient solutions for life’s most fundamental problems, it adopts them as invaluable family heirlooms, passing them down as one species evolves into another. So it was reasonable ...
