Induction of squamous metaplasia in organ cultures of hamster trachea by naturally occurring and synthetic fibers

Induction of squamous metaplasia in organ cultures of hamster trachea by naturally occurring and synthetic fibers. Woodworth, Craig D.; Mossman, Brooke T.; Craighead, John E. (Coll. Med., Univ. Vermont, Burlington, VT 05405, USA). Cancer Res., 43(10), 4906-12 (English) 1983. CODEN: CNREA8. 12001-29-5 and 66733-82-2 which are cas registry numbers are also used here. ISSN: 0008-5472. DOCUMENT TYPE: Journal CA Section: 4 (Toxicology) Several naturally occurring and synthetic fibrous materials and their nonfibrous analogs were assessed for their ability to induce metaplastic changes in tracheal mucosa of the hamster. Exposure to both crocidolite [12001-28-4] asbestos and fiberglass resulted in increases in squamous metaplasia over a range of dosages (1.0, 4.0, 16.0 mg/mL). Attapulgite [12174-11-7] and both long- and short-fiber prepns. of chrysotile [12001-29-5] asbestos had similar but less marked effects. Nonfibrous analogs of each material (riebeckite [66733-82-2], antigorite [61076-98-0], and glass particles) failed to produce metaplasia. Asbestos, and fibrous materials in general, appear to stimulate squamous metaplasia because of their fibrous geometry. .
