Characteristics of a feline mammary carcinoma cell line

The establishment of an epithelial cell line, JM, from a feline mammary adenocarcinoma is described. In vitro, the morphological and cultural properties of these cells, their surface features such as lectin binding and their response to hormones were ascertained. In vivo, they are tumorigenic in athymic nude mice inducing tumour nodules composed of epithelia-like cells.
