SCOPE OF WORK

 

Specific Aim 1: Acute transplantation to
demonstrate hemocompatibility

 

[Goal: Demonstrate the ability
to anastomose the revascularized liver graft onto the liver and maintain blood flow >50% of initial output after 30 minutes of perfusion]

 

		1.	Isolate and determine source of porcine endothelial cells (n=4)

 

		a.	Autologous versus Allogeneic porcine vein harvest and outgrowth

 

		b.	Outgrowth kinetics will be determined from autologous, if outgrowth is >4 weeks then allogeneic porcine cord endothelial cells
will used as defined in previous ILP award

 

		2.	Production of revascularized liver grafts (n=12, 2 per animal)

 

		a.	Perform vein harvest on n=6 animals if autologous model is used, and perform outgrowth

 

		b.	Growth of allogenic endothelial cells if deemed necessary in Specific Aim 1-A

 

		c.	Seeding of endothelial cells according to defined SOP and monitoring growth via metabolic assays (7 days) resulting in 12 transplantable
grafts

 

		3.	Acute Transplantation (n=6 animals, n=12 grafts) [+/- Heparin in graft]

 

		a.	Perform anastomosis of the revascularized liver graft to the portal vein for 30 minutes (n=3- heparin, n=3 +heparin)

 

		b.	In the same animal, perform partial liver resection followed by anastomosis of liver graft via the identified portal vein in the graft
(n=3 -heparin, n=3 +heparin)

 

		c.	Monitor pressure and output perfusion with a target to achieve continuous perfusion for 30 minutes

 

		d.	Determine optimal location for long-term transplantation for Specific Aim 2

 

Specific Aim la: Hepatocyte Isolation and
Seeding Development

 

[Goal: Determine the optimal
hepatocyte isolation efficiencies to isolate >50 million hepatocytes and define the seeding protocol for use in Specific Aim 2 that
results in >50% viable hepatocytes after 7 days in culture]

 

		1.	Isolation and protocol development for porcine hepatocytes (n=6)

 

		a.	Protocol development and isolation of porcine hepatocytes from resected porcine or human liver tissue (n=6)

 

		b.	Goal of isolating 50 million viable hepatocytes

 

		2.	Seeding isolated hepatocytes via injection versus perfusion into liver grafts (n=6)

 

		a.	Perform n=3 direct injection (n=3) into a revascularized liver graft

 

		b.	Perform n=3 perfusion of hepatocytes into a revascularized liver graft

 

		c.	Measure metabolic output of liver grafts for 7 days during cell culture

 

    

    

    

 

		d.	Perform histology, viability staining and proliferation staining on seeded grafts

 

		e.	Perform hepatocyte metabolic activity assays on seeded grafts

 

		3.	Finalize hepatocyte seeding protocol

 

		a.	Based on Specific Aim 1 a-B, an optimized protocol will be drafted for use in Specific Aim 2

 

		b.	Based on Specific Aim la-B, an optimized protocol will be drafted for use in Specific Aim 2

 

Specific Aim 2: 45 Day Transplantation to
Demonstrate Efficacy of Revascularized Liver Graft

 

[Goal: Determine the ability
of the revascularized liver graft to become recellularized by the native liver or the ability to be seeded with hepatocytes resulting
in the detection of viable hepatocytes within the graft at 45 days]

 

		1.	Production of transplantable liver grafts (n=20)- 14 days

 

		a.	Production of two liver grafts per selected animal (1-implant and 1-characterization)

 

		b.	Seeding of endothelial cells according to defined SOP and monitoring growth via monitoring metabolic activity

 

		c.	Transplantation of one liver graft and histological analysis of the remaining graft as a control

 

		2.	Long-term transplantation (45 day transplantation, n=10) [+ immunosuppression if allogeneic endothelial cells are use]

 

		a.	Revascularized liver grafts (n=5)

 

		i.	Partial liver resection followed by anastomosis of hepatic and portal vein to exposed liver surface

 

		b.	Revascularized + Isolated Hepatocytes (n=5)

 

		i.	Partial liver resection followed by anastomosis of hepatic and portal vein to exposed liver surface

 

		ii.	Hepatocyte isolation and added to graft based on Specific Aim la-C

 

		c.	Control (n=4)

 

		i.	Partial liver resection followed without anastomosis of an liver acellular graft on adjacent lobe

 

		3.	Post Transplant Analysis

 

		a.	Histology 24 slides per transplant

 

		i.	Isolation of 3 blocks per graft (proximal and distal to transplantation site) and 8 sections (4 serial-200um-4 serial)

 

		ii.	H&E staining

 

		iii.	Albumin staining for the characterization of hepatocytes

 

		iv.	Ki67 staining for the characterization of hepatocyte proliferation

 

		v.	Extra slides for endothelial or epithelial staining if needed
