METHODS FOR MAKING EMBRYONIC CELLS, EMBRYOS, AND ANIMALS SENSITIZED TO STRESS

摘要

Embodiments of the invention are based upon the discovery that exposure of cleavage-stage embryos to a stress inducer, e.g. heat shock or chemical, renders the exposed embryos more sensitive to a secondary treatment with a stress inducer, e.g. heat shock or chemical inducer. Accordingly, the present invention is directed to methods for making embryos, embryonic cells arising from them, and animals and plants that are sensitized to stress, e.g. physiologic or chemical stressors. Methods of screening for inducers and inhibitors of stress using, as test model systems, embryonic cells, embryos, animals, and plants that are sensitized to stress are also disclosed.
