    摘要: A method for culturing a recombinant host cell comprising: determining a polypeptide factor for a polypeptide factor-dependent host cell; transforming said host cell with nucleic acid encoding said polypeptide factor; transforming the host cell with nucleic acid encoding a desired protein; and, culturing the transformed host cells in a medium lacking the polypeptide factor.

    摘要: A novel bronchial or bronchiolar epithelial cell from normal neonatal mammalian lung has been isolated, established and maintained for multiple passages in the absence of serum, without undergoing crisis or senescence. By careful manipulation of the nutritional/hormonal microenvironment we have been able to select, from a heterogeneous population, a single epithelial cell type which can maintain highly differentiated features in vitro. This cell type has characteristics of bronchiolar epithelial cells. A clonal line, RL-65, has been selected and observed for more than 3 years in continuous culture. It has been characterized by ultrastructural, morphological and biochemical criteria.
