Scientists have created an infant ‘chimeric’ monkey by injecting a monkey embryo with stem cells from a genetically distinct donor embryo. The resulting animal is the first live-born chimeric primate to have a high proportion of cells originating from donor stem cells. However, the monkey had to be euthanized when it was...
Scientists have filmed an ancient egg-laying mammal named after Sir David Attenborough for the first time, proving it isn’t extinct as was feared....
Cytoplasmic lattices (bundles of fibres floating in the cytoplasm) in mammalian egg cells seem to be storage sites for many proteins that are essential for the development of the early embryo.
