Comparison of Periodontal Ligament Cell Lines with Adenovirus- and Lentivirus-Mediated Human Telomerase Reverse Transcription Expression.

ABSTRACT: The aims of this study were to generate periodontal ligament (PDL) cells that have adenovirus- or lentivirus-mediated overexpression of human telomerase reverse transcriptase (hTERT) and to compare the osteogenic and proliferative abilities of the two cell lines to establish an efficient and stable cell model that will be more suitable for studies of PDL regeneration. After construction of the recombinant adenovirus plasmid pAd-pshuttle-cmv-hTERT, human PDL cells were infected by packaged adenovirus and lentivirus particles to establish two PDL cell lines. The expression levels of hTERT and mRNA for alkaline phosphatase, osteopontin, osteocalcin, bone sialoprotein, core-binding factor (runt-related transcription factor 2), and type I collagen were assessed for each cell line.
