Using proteins found in egg cells, he said, it may be possible to prompt adult cells, such as skin cells, to revert into stem cells similar to those in embryos.

IN a previous communication1 the presence of an inhibitor of cytochrome oxidase in the unfertilized sea urchin egg was described. It was shown that its activity decreases considerably following ...
