A new model system for studying early embryonic development – Tech Explorist
Cell biologists at the Max Planck Institute (MPI) have now developed a new model system for studying early embryonic development.
Human somatic cells commonly have 46 chromosomes, which together convey the genetic information. These chromosomes are first united at fertilization, 23 from the dad’s sperm and 23 from the mother’s egg.
After fertilization, the parental chromosomes at first exist in two separate compartments, known as pronuclei. These pronuclei gradually move towards one another until they come into contact. The pronuclear envelopes then dissolve, and the parental chromosomes unite.
