Telomerase is enriched in germline lineage cells and embryonic stem cells [26–29]; previous data have indicated that telomerase reverse transcriptase (TERT) and telomerase activities were significantly higher in preeclampsia placentae than in the control group placentae according to different gestational ages [30, 31], which may cause a lengthening effect of TL in PE cases as well. Here, TERT is linked to preeclampsia.
