NCI-H322 was derived in 1981 from a primary bronchioalveolar carcinoma of the lung from a 52 year old male taken prior to treatment. Ultrastructural studies of this non-small cell carcinoma cell line demonstrated the presence of cytoplasmic structures characteristic of Clara cells. NCI-H322 do not express UDP-glucuronosyltransferase, but are reported to express glutathione-S-transferase and phenol sulfotransferase. Expression of protein and RNA of SP-A, the major surfactant-associated protein was detected. The cells produce tumours in athymic mice.
