Little effect was noted on the labeling indexes of the gingival epithelium in aging mice after gingival excision. However, significantly diminished labeling indexes, shifted peak activities to later time periods, and delayed tissue regeneration were observed in associated connective tissues. The effects of aging were most pronounced on the connective tissue compartments that retained their cell proliferative potential despite aging.
