to determine if progression of the epithelium through the cycle is accompanied by changes in cytoskeletal composition , particularly the keratins , the polypeptides in cytoskeletal extracts from balb/c mouse mammary tissues were analyzed by one- and two-dimensional gel electrophoresis combined with immunoblots using polyclonal and monoclonal antikeratin antibodies .
