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), 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 interests would be greatly enhanced by further characterization and improvements in the culture technology that would ultimately result in the cell line not requiring feeder cell support and 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. Further, 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 functions of an intact liver. The primary interest of Hepalife 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 itself, 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 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 func tion responses, and c.) cell transformation responses, i.e., loss of normal differentiation.

C.

Approach and Methodology

ARS will study experimental 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 an artificial liver device, and for their use in the in-vitro assay of metabolic, toxic, or carcinogenic responses.  Specific project objectives are the following:

1)  Develop feeder-cell-independent and serum-free medium cell culture systems allowing the growth and differentiation of ARS-PICM-19 cells, or subclones or subpopulations of the ARS-PICM-19 cells, under defined conditions.

2)  Develop spheroid cultures of PICM-19 cells without STO feeder cells and testing of rotating cell culture system (RCCS) for production and maintenance of spheroids.

3)  Investigate effects of accessory cells obtained from pig liver on ARS-PICM-19 growth, differentiation, and metabolic function.

4)  Assay ARS-PICM-19 cells and spheroids for liver specific functions by measuring  P450 activity, γ-glutamyltranspeptidase activity, urea production, and ammonia clearance.

5)  Assay ARS-PICM-19 liver specific protein synthesis and secretion by electrophoretic, immunochemical, or mass spectrophotometric techniques.

6)  Develop and test, by in-vitro assay, flow-through bioreactors that enable the growth, differentiation, and  maintenance of metabolic function of the ARS-PICM-19 cell line, or its derivative cell lines, over long term culture (1-3 months).

 7)  Develop and test multi-well cell culture formats for the in-vitro assay of the effects of

various test compounds on the metabolism and viability of ARS-PICM-19-derived hepatocytes or bile ductules.

8)  Genetically engineer ARS-PICM-19 cells to create derivative cell lines containing gene reporter constructs, e.g., green fluorescent protein (GFP) based constructs, so that GFP expression is linked to various cell metabolic responses or stimulation of various cell signal transduction pathways.

9)  Develop cell transformation assay formats to demonstrate and enable the utilization of the ARS-PICM-19 cell line for the study of  mutagenic or carcinogenic processes.

Hepalife will provide funds for the salary of one post-doctoral researcher, one support scientist, and one technician for a period of three years and funds for the associated laboratory supplies and professional activities involved with conducting the CRADA objectives.
