| Comments | "During its entire lifetime, however, the rat produces and discards about 10^13 epithelial cells from its small intestine alone, and almost as many cells from various other epithelia (primary source). Its risk of being overwhelmed by variants, is, in principle at least, related to this total of 10^13." |
