News for 'HPLF' - (HepaLife(TM) Develops New Liver Stem Cell Lines for Bioartificial Liver Device; Data Presented at Scientific Conferences)


BOSTON, Jun 25, 2008 (BUSINESS WIRE) -- HepaLife Technologies, Inc. (OTCBB:
HPLF) (FWB: HL1) (WKN: 500625), today announced the development of two new
derivative cell lines from the Company's patented PICM-19 liver stem cells for
use in HepaLife's first-of-its-kind bioartificial liver device currently under
development for the treatment of human liver failure.

"These two cell lines have unique and special functionalities, and make it
possible to more closely model the function of the natural liver in our device
than before," explained Mr. Frank Menzler, President and CEO of HepaLife
Technologies, Inc. "These cell lines further enable us to progress more rapidly
in our efforts to scale-up the manufacturing into larger-scale production of our
cells, an important requirement for using the cells inside an artificial liver
device."

Researchers presented initial data on the Company's new cell lines at the 6th
Annual Meeting of International Society for Stem Cell Research in Philadelphia,
PA and the 54th American Society of Internal Artificial Organs annual conference
in San Francisco, CA, earlier this month.

The two immortalized unipotent porcine liver stem cell lines are: the
'PICM-19H', capable of differentiating exclusively into 'hepatocytes' or liver
cells with the ability to express hepatocyte or liver-cell function; and, the
'PICM-19B,' capable of differentiating exclusively into bile duct cells with the
ability to express bile duct cell function.

In ongoing tests, scientists have confirmed that HepaLife's PICM-19H cells
favorably differentiate into hepatocytes as evidenced by their 'morphology', or
form and structure. The PICM-19H also express the most important liver functions
key to replicating the human liver, expressing hepatocyte functions such as
Phase I (P450) and Phase II metabolic activity, serum protein synthesis, low
gamma-glutamyl transpeptidase (GGT) activity, ammonia clearance and urea
synthesis similar to primary adult cells. The cells have demonstrated the
ability to successfully retain the highest levels of liver-specific metabolic
activity over prolonged periods of time.

The PICM-19B cell line, which differentiates exclusively into functional bile
duct cells (cholangiocytes) show that the cells form confluent (complete) cell
monolayers in culture, are basolaterally polarized cells exhibiting basal
membrane fluid transport, have high GGT activity and have greatly reduced serum
protein production.

Intended for the treatment of liver failure, the HepaLife(TM) Bioartificial
Liver device consists of three basic components: (1) a plasma filter, separating
the patient's blood into blood plasma and blood cells; (2) the bioreactor, a
unit filled with the patented PICM-19 liver stem cell line which biologically
mimics the liver's function; and (3), the HepaDrive(TM), a perfusion system for
pumping the patient's plasma through the bioreactor while controlling gas supply
and temperature for best possible performance of the cells.

ABOUT HEPALIFE TECHNOLOGIES, INC.

Based in Boston, Massachusetts, HepaLife Technologies, Inc. (OTCBB: HPLF) (FWB:
HL1) (WKN: 500625) is a developer of cell-based medical technologies addressing
prevalent human health concerns.

HepaLife is developing the first-of-its-kind bioartificial liver device intended
for the treatment of liver failure using the Company's patented PICM-19 liver
stem cell line. The HepaLife(TM) bioartificial liver, currently under
development, is designed to serve as a supportive device, either allowing the
liver to regenerate upon acute liver failure, or to bridge the patient's liver
functions until a transplant is available.

Utilizing its patented liver stem cell line PICM-19, HepaLife is designing
testing platforms to improve the pharmaceutical industry's capability to
evaluate drug toxicity and possible side-effects before pharmaceutical compounds
are commercially distributed.
