What is the main advantage of arterial perfusion?
Arterial perfusion under oscillating pressure conditions leads to more homogeneous decellularization results compared to portal venous perfusion.
How does oscillating pressure affect perfusion?
Oscillating pressure mimics intraabdominal pressure changes during respiration, optimizing liver micro perfusion.
What methods were used to assess decellularization?
Decellularization was assessed through macroscopic observation, histological analysis, and biochemical analysis.
What is the purpose of cannulating the liver?
Cannulation allows for selective perfusion of the portal veins and hepatic arteries, which is essential for the decellularization process.
Why is decellularization important?
Decellularization is crucial for organ transplantation and tissue engineering, allowing for the creation of scaffolds for cell repopulation.
