Decellularisation left the 'collagen scaffolding' intact in order to customize the cellular content of a heart. Amazing stuff.
The way this translates into a heart transplant without the fear of rejection is that a new collagen structure could be injected with a person's genetic content introducing heart cells to literally create a new heart.
But, in contrast to 'growing' a heart from stem cells this would still require a donor for the collagen structure to exist.
