Abstract
Disclosed is a process for treating body tissues such as vascular structures to remove barriers to recellularization before and after implantation in a human host. The body tissue, for example a heart valve, is subjected to a hypotonic/hypertonic treatment, then treated with enzymes to provide a collagen- and elastin-containing matrix suitable for recellularization.
