Finally, in line with our results, there is no gender bias in KLF1(K74R)‐related longevity, and with no obvious detrimental effects, such as restricted growth and fecundity,[6a] osteoporosis, impaired wound healing, abnormal metabolism, attenuated immunity,[40] tissue fibrosis[41] or teratoma,[42] etc., as reported in other longevity model systems. This evidence concerns the gene KLF1 and teratoma.
