Growth and metastasis of two canine mast cell tumors in SCID mice.
Intermediately differentiated mast cell tumors in two dogs were subcutaneously xenotransplanted into severe combined immunodeficiency (SCID) mice. Both tumors primarily grew and were serially transplantable in SCID mice. The histological features of the xenografts were similar to those of original tumors in dogs. Both of these subcutaneous tumors were judged as connective tissue mast cells by toluidine blue stain. One of the two xenografts metastasized to the tracheobronchial lymph nodes, omentum, mesentery, subpleural region and retroperitoneum of the SCID mouse. These canine mast cell tumor xenografts in SCID mice may be valuable tools for investigating the growth and metastatic behaviors of the tumor.
