摘要:
Lymphotoxin-producing human T-cell hybridomas are incubated in a medium containing phorbol myristate acetate, concanavalin-A or a mixture thereof, the resulting cells are fractionated by sucrose density-gradient centrifugation method to isolate a messenger RNA in 12.6S to 14.6S fractions, and a gene containing a part encoding a polypeptide having a lymphotoxin-activity is prepared from the messenger RNA. The gene is represented by the base sequence of the Table 1 as herein given. Using the present gene, a new lymphotoxin having the amino acid sequence (I) or (II) as given herein can be obtained by genetic engineering technology.

摘要:
To provide an immortalized capillary pericyte line which maintains the original function/property of the cell line-deriving tissue, its establishment method, and the screening method for useful substance using the immortalized capillary pericyte line. Cerebral tissue of a transgenic rat carrying the large T antigen gene of SV40 thermo-sensitive mutant line tsA58 is homogenized and the resultant brain capillaries are treated with protease, thus obtained brain capillary cells are subcultured to establish an immortalized cell that expresses SV40 thermo-sensitive large T antigen, PDGF receptor β, and Angiopoietin-1. In addition, the immortalized vascular pericyte line has ability to deposit calcium on matrix by dense culture.
