We extended the cell life from 7–15 days to over 250 days by housing them in a scaffold system we call the “cell chip.”. This allowed organ cells to keep producing growth factors for a long time without changing the cells. WebCells that exhibit that type of property are known as “immortalized” cell lines, so named because of their apparent ability to be cultured indefinitely. That property is what made HeLa cells such a star in research requiring human cells to be cultured in vitro.
