From New Scientist comes news of the womb-on-a-chip:
Fujii’s team has created a “lab on a chip” that is 2 millimetres across and 0.5 millimetres high, in which up to 20 eggs can be fertilised and then grown until they are ready for implantation. Endometrial cells, which line real wombs, are also grown in the device, so that the chemicals they produce can reach the embryos and help them grow. “We are providing the embryos with a much more comfortable environment, mimicking what happens in the body,” Fujii says.
Experiments in mice suggest that the chip is more successful than traditional IVF at producing embryos that will grow into healthy fetuses. Of 50 fertilised eggs grown on the chip, 30 developed into early embryos, compared to 26 out of 50 fertilised eggs grown through “microdrop” IVF.
Better than test tubes.
