P53 as a regulator of cell differentiation

, : P53 as a regulator of cell differentiation. Official Gazette of the United States Patent & Trademark Office Patents 1264(2), Nov 12

The present invention involves the role of p53 in the differentiation of embryonic tissues. More particularly, the present invention provides methods of the blocking of p53 function in embryonic tissues, and the use of these tissues as screening tools for substances that are capable of overcoming the p53-related block in differentation, both in vitro and in vivo. The similarities between undifferentiated embryonic cells and tumor cells is evident, and thus these assays serve as a model for possible cancer therapeutics. In addition, methods for identifying additional cellular components that interact p53 or p53-related pathways are provided.
