Fibroblasts found to have surprising proliferative potential into old age

September 1, 2002

San Antonio - One take-home lesson from a study on aging is that even the fibroblasts of very old people have significant proliferative potential, James R. Smith, Ph.D., said. "This suggests that fibroblasts may not be the best cells to use in determining a relationship between in vivo and in vitro aging," he said.
