SCHEDULE 2

STATEMENT OF WORK




A.

Introduction/Background




ARS has developed several in vitro model systems to investigate various aspects of hepatic gene expression and metabolic regulation. These systems encompass both established cell lines and primary liver cell cultures. One stem-like cell line, derived from porcine epiblast (embryonic) tissue is the ARS-PICM-19 cell line (ARS patent #5,532,156), hereafter referred to as PICM-19 cells, has been partially characterized and is a non-transformed immortal cell line that possesses many characteristics similar to that of intact liver parenchymal cells. ARS is interested in further characterization and improvements in the culture technology that would ultimately result in the cell line not requiring feeder cell support for growth in suspension culture, or for growth in a completely serum-free defined medium. These advancements would facilitate our understanding of regulatory events in pig liver gene/proteome expression and in regulation of nutrient metabolism. It has already been demonstrated that the unique hepatic characteristics of the ARS-PICM-19 cell line would have potential application for use in the production of a rescue device for human patients in liver failure (ARS patent # 5,866,420; “Artificial Liver Device”, granted to ARS on 2/2/1999). To date, the cellular components of artificial liver devices that are being tested by other institutions are based on freshly isolated porcine hepatocytes, human transformed tumor cells, or poorly defined stem-like cells prepared from fresh human adult liver tissue. It is widely recognized that the greatest hindrance to the development of a completely functional artificial liver rescue device is the lack of an appropriate defined cell line that will provide the life supportive functions of an intact liver. The primary interest of the Cooperator is to explore the possibility that the ARS-PICM-19 cell line is indeed the most appropriate cell line to use in such a device.




B.

Objective




The overall objective of the work is to optimize the patented ARS-PICM-19 cell line as an in vitro model of the pig liver. The first objective is to investigate and discover culture conditions for the ARS-PICM-19 cell line, or modifications of the ARS-PICM-19 cell line technology that will optimize function, i.e., culture conditions or cell line modifications that will enable, as closely as possible, the reproduction of normal pig liver functions in an in vitro environment.  Directly related to the first objective will be the second and third objectives.  The second objective is adapting and applying the optimized ARS-PICM-19 cell line technology to the development of an extracorporeal liver assist device as, for example, described in patent #5,866,420.  The third objective is to use the ARS-PICM-19 cell line in the development of in vitro assay formats for testing, a.) cell metabolism and toxicity responses, b.)  hepatocyte and bile duct epithelium cell function responses, and c.) cell transformation responses, i.e., loss of normal differentiation.




C.

Approach and Methodology




ARS will study culture conditions for the ARS-PICM-19 cell line, its derivative cell lines, or other pig epiblast-derived liver cell lines (as described under ARS patent #5,532,156, “Hepatocyte Cell Line Derived from the Epiblast of Pig Blastocysts”) so as to optimize their hepatocyte functions for use as an in vitro liver model, for their use in a flow-through bioreactor (“HepaLife bioreactor”), a multicompartment flow-through hollow-fiber bioreactor currently manufactured by Stem Cell Systems GmbH, Germany, or any other bioreactor design designated by HepaLife Biosystems, Inc., and for their use in the in vitro assay of metabolic or toxic responses.  




D.

ARS’ Responsibilities




1. Conduct these portions of the research project or perform the following tasks:




a. Provide advisory duties of two part-time (10%) USDA senior scientists.

ARS & COOPERATOR’S Joint or Mutual Responsibilities




1.

Perform these portions of the effort jointly:




a. Develop strategies for the design or testing of flow-through bioreactors to grow and maintain ARS-PICM-19, or its derivative cell lines, or related pig liver epiblast-derived cell lines.




b. Evaluate efficacy of ARS-PICM-19, its derivative cell lines, or related epiblast-derived pig liver cell lines, in an in vitro pig liver model system for potential use in an extracorporeal liver assist device and in the development and testing of in vitro formats for assaying metabolic, toxicological, and carcinogenic responses in pig hepatocytes and bile ductules.

b.

Analyze scientific raw data and experimental results. 

c. Characterize and validate PICM-19 performance in comparison with alternative cell source.

1) Cell sources. 

a)  Primary pig hepatocyte.

b)  Primary human hepatocyte.

c)  Other hepatocyte cell lines or primary hepatocyte cultures of interest.




2) Characterization assays included but are not limited to:

  

a)  Urea production.

  

b)   P450 activity.

c)  Quantization of porcine liver proteins alpha-fetoprotein and albumin. 




d.  Develop and validate alternative expansion methods including:

1) T-flasks/flat-bed multi-plate culture dishes.

2) Hollow-fiber bioreactors

3) Suspension culture as individual cells or spheroids (e.g., shaking tubes or

 shaking flasks stirrer flasks, rotating cell culture system (RCCS), bioreactors,

 others).

4) Suspension culture on microcarrier beads or scaffolds.




e.  Validate conditions, methods, biosystem operating life-span and processes for flow-through lab-size and clinical-size bioreactors that enable the growth, differentiation, and maintenance of PICM-19 cells and their 






14












                                                               

     







metabolic function.




f. Develop and validate alternative mouse and human feeder-cells, feeder-cell-independent culture, and serum-free media that enable the growth, differentiation, and maintenance of  PICM-19 cells.  




g.  Develop and validate custom growth factor containing suspension and anchorage-dependent medium formulations as required (including serum-free or defined media).




h.  Test function and viability of PICM-19 cells for up to 96 h exposures to normal and specific disease-state human blood plasmas in T-flasks and, if successful, in HepaLife bioreactor for up to 30 days.




i.  Support process or methods development for use of PICM-19 cell-containingHepaLife bioreactor in animal models of acute liver failure (e.g., rat treated with toxic amounts of  Tylenol or pig with liver resection) for demonstrating HepaLife bioreactor operating life-span and life supportive liver replacement function.




j. Develop and validate, by in vitro assay, the HepaLife bioreactor, or other flow-through bioreactors as necessary, to enable the growth, differentiation, and maintenance of PICM-19 cells and their metabolic function over long term culture (up to 3 months) in the bioreactor.




k. Validate the stability of the PICM-19 cells by analysis of growth, differentiation, and expression of defined “biomarkers” (e.g., serum-protein production, cytochrome P450 activity, ammonia clearance, urea production) over multiple passages (~50) and extensive periods of continuous culture equivalent to the number of cell divisions required to scale up (e.g. 30,000 liter bioreactor scale at a cell density of one million cells per milliliter).

.

l. Develop, validate, and utilize various liver-specific biochemical assays for the comparison of PICM-19 cell function in T-flask cultures and the HepaLife bioreactor using the same cells at the same time in parallel cultures.




m. ***




n.  Facilitate the creation of a Master Cell Bank of PICM-19 and STO cells:

1)  B/F Test

2)  Mycoplasm Test

3)  Adventitious Agents Test

4)  PERV (w and w/o membranes of bioreactor)

5)  Tumorigenicity Test

6)  Specific tests/assay development

7) Expansion of PICM-19 and STO stocks for creation of “Master Cell Banks” (MCB) and “Working Cell Banks” (WCB) under cGLP and cGMP protocols

8) Cryopreservation of PICM-19 “MCB” and “WCB”

9) Cryopreservation of STO stock cell “MCB” and “WCB”




n. Create a “Research Cell Bank” of PICM-19 cells and STO stock cells by the cryopreservation of 300 hundred 1.5 ml aliquots of cells containing 5-10 million cells per aliquot.




o. Develop and test multi-well cell culture formats for the in vitro assay of the effects of various xenobiotic compounds on the metabolism and viability of  PICM-19 hepatocytes or bile ductules.  Xenobiotic compounds will include but not be limited to the following:  3-methylcholanthrene (CYP1A1, 1A2 inducer), rifampicin (CYP3A4 inducer), Na-phenobarbital (CYP2B6, 2C9 inducer,testosterone (CYP3A4, 3A5 inducer), secobarbital (CYP2C9 inducer), diazepam (CYP1A2, 2C19, 2C8, 3A4 inducer), dexfenfluramine (CYP2D6 interaction), and Acetaminophen  (CYP2E1 interaction).   Toxic compounds will include but not be limited to the following: amphetamine sulfate, caffeine, carbon tetrachloride, chloamphenicol, chloroquine phosphate, ethylene glycol, ethyl alcohol, isopropyl alcohol, hexachlorophene, lindane, lithium sulfate, malathion, and nicotine.
