During embryo development, cells assess their position (positional information) by sensing different concentrations of a morphogen gradient; such gradients have been proposed to arise by diffusion ...
Reproductive success requires the development of viable oocytes and the accurate segregation of chromosomes during meiosis. Failure to segregate chromosomes properly can lead to infertility, ...
Early development of an embryo is solely supported by maternally deposited RNAs and proteins until its own genome is activated through a process called zygotic genome activation (ZGA). Recent research ...
