TR146

TR146 was derived from the neck node of a 67 year-old female (primary tumour was sited in buccal mucosa). The patient had had previous radiotherapy (6,000 rads) and neck dissection. TR146 is tumourigenic in female (nu/nu) mice leading to the production of rapidly progressing tumours. Histology: well-differentiated keratinizing squamous cell carcinoma.
