PROCESS FOR THE PRODUCTION OF PERMANENTLY CULTURABLE ANIMAL AND HUMAN CELL LINES AND THE USE THEREOF

摘要

A method for obtaining permanently culturable human and animal cell lines, as well as uses for these cell lines, are disclosed. The method involves fusing cells of a non-immortal cell line with cytoplasts or cytoplasma fractions of "immortal", transformed cells such as immortal myeloma cells, ascites-tumor cells or Epstein Barr Virus infected cells. Once fusion takes place the product is a permanently culturable variant of the previously normal cell line.
