BioNews - Moving pinboard boosts IVF success: Currently, embryos are fertilised in a dish, and left there to culture for a few days before being implanted. However, this doesn't mimic how embryos naturally gestate.
Embryos really grow in the body in a moist environment, not a fully fluid environment, it's continually moving because of muscle contractions. Biomedical engineers at the University of Michigan developed a culture chip half the size of a credit card to copy these conditions. The embryos sit in small wells, rather than free in a dish, with channels filled with a nutrient and hormone mixture underneath. The bed of pins pulses up against the channels, pumping the mixture over the embryos to rock them and remove waste products.
