What is the difference between regeneration and repair in tissue healing?

Two outcomes describe tissue healing: regeneration and repair. Regeneration restores tissue by the proliferation of the same-type cells that originally formed it, reconstituting the original architecture and potentially full function. Repair, in contrast, replaces the lost tissue with scar tissue—fibrous connective tissue—that preserves continuity but does not recreate the exact structure, so function may be impaired. Tissues vary in regenerative capacity (liver can regenerate well, for example), while others heal mainly by repair with scar. This distinction—regeneration restoring architecture through same-cell proliferation versus repair producing scar tissue and possible functional loss—is the best way to differentiate the two processes.
