Glycogen-Containing Cells of Estrogen-Induced Renal Tumors of the Hamster

Abstract

Cells which contain glycogen, and which may arise from the connective tissue matrix, can be demonstrated in the estrogen-induced renal tumor of the hamster when the tumor tissue used has either been lyophilized or frozen and then substituted in absolute alcohol containing mercuric chloride. Glycogen has not been found previously in this type of tumor. Studies of the role of glycogen in this type of neoplasm nmay elucidate mechanisms of tumorigenesis.
