Blood cell factors and tumor growth in the cheek pouch of the golden hamster (Mesocricetus auratus).

Factors affecting hamster sarcoma growth in the cheek pouch.

The cheek pouch of the golden hamster (Meso cricetus aura@us) has been shown to be a favorable transplantation site for a variety of homologous and heterologous malignant tumors, including a few human epidermoid carcinomas and sarcomas (5,10,1@). Sinceaccuratemeasurements oftrans plant volume are possible according to the technic described by Lutz and co-workers, the kinetics of tumor growth an...

Spontaneous differentiated squamous cell carcinoma of cheek pouch in a Syrian hamster

A 2-year-old male hamster was presented because of left facial swelling and salivation. Necropsy wasperformed and affected cheek pouch with tissue samples of regional and internal organs were submitted forhistopathological study. In histopathological examination it was found that the tumor consisted of cords andislands of tumoric epithelial cells which were diffused in the dermis. Vacoulation o...

Mechanism of ovarian disruption by neonatal DES exposure: A modified ectopic approach

Introduction Diethylstilbestrol (DES) is the classic example of an endocrine disruptor and exemplifies the damage done by xenoestrogens. DES is a non-steroidal, synthetic estrogen that was developed to supplement a woman's natural estrogen production. DES was first prescribed by physicians in 1938 for women who experienced miscarriages or premature deliveries that were believed due to insuffici...

A New Spontaneous Hamster Carcinoma Associated with a Positive Erythroagglutination Reaction and Anemia.

The appearance of a spontaneous carcinoma in an untreated male golden hamster has provided us with a very useful additional experimental model with which to study the anemia of malignancy. The tumor, probably of salivary gland origin, has been serially transplanted in the cheek pouch or flank of normal hamsters through 70 trans plant generations. The growth characteristics are stable and predic...
