BOSTON--(BUSINESS WIRE)--Jun 25, 2007 - HepaLife Technologies, Inc. (OTCBB: HPLF) (FWB: HL1) (WKN: 500625) today announced that new data presented at an international influenza research conference demonstrates that HepaLife's patented PBS-1 cell line outperforms current cell technologies at replicating human influenza virus inside its cells. The most important step towards the production of a cell-culture based vaccine against a targeted virus is the ability to efficiently grow the same virus in a cell substrate.

Data presented at the "Options for the Control of Influenza VI Conference," June 17-23, 2007, in Toronto, Canada, compared human influenza virus replication capabilities of several established cell lines. HepaLife's PBS-1 cell line significantly outperformed today's prevailing cell systems, including VERO (African green monkey kidney cell), MDCK ("Martin-Darby Canine Kidney") and primary chick kidney cells ("CEK").

"I'm very proud of the efforts that our research team has made in demonstrating the superiority of HepaLife's PBS-1 cells at an international conference dedicated to identifying cutting-edge solutions to influenza," commented Mr. Frank Menzler, President and CEO of HepaLife Technologies, Inc. "I'm especially pleased that our cell line is able to successfully grow targeted human influenza virus where other leading commercial and academically-researched cells lines have either failed to keep up, or are simply unable to do so."

According to test results, HepaLife's PBS-1 cells developed higher influenza 'titers' -- or concentration of influenza -- than CEK cells. In contrast, MDCK and VERO cells were unable to replicate virus and produce comparable results. Importantly, the tested influenza strains had not been previously adapted to any of the cel
