Tissue culture, protein and collagen synthesis in antibiotic sterilized canine heart valves

Abstract
Viability of canine heart valve leaflet fibroblasts was assessed after varying periods of sterilization and storage in antibiotic-nutrient solution. Tissue culture and assessment of protein and collagen synthesis showed that tissue obtained undsr optimal conditions rarely retains viability beyond 3 weeks in antibiotic-nutrient solution and is severely impaired after 2 weeks. This casts serious doubts on viability in current clinical homograft valve practice.
