CHD4 has been identified as a tumor suppressor and regulator of stemness in endometrial carcinoma cells, but little is known about the tissue-specific roles of CHD4 in the endometrial epithelia in vivo. We generated a conditional Chd4 floxed allele and combined it with BAC-Sprr2f-Cre to drive Chd4 loss in the endometrial epithelium. Here, CHD4 is linked to neoplasm.
