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.
摘要:
A method for enhancing the survival and/or proliferation of Schwann cells (especially human Schwann cells) in cell culture is disclosed which involves culturing the cells in serum free culture medium comprising gas6 and other mitogenic agents, such as heregulin and forskolin. The culturing step is generally preceded by a pre-incubation period wherein nerve tissue comprising the Schwann cells is cultured under appropriate conditions and for a period of time such that demyelination occurs. The isolated Schwann cells can be used as cellular prostheses to treat patients with nervous system injuries. The invention also provides a cell culture medium for culturing Schwann cells.

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.
