METHODS FOR CLONING MAMMALS USING REMODELING FACTORS

摘要

Methods and compositions are provided for remodeling nuclear donor material used in nuclear transfer procedures. By exposing donor chromatin to one or more exogenous remodeling factors, the limited ability of mammalian oocytes to remodel the chromatin of differentiated cells, including fetal and live-born somatic cells, can be increased, resulting in dramatically improved cloning efficiencies.
