The phenotype of the immortalized human odontoblast-like cell line / 实用口腔医学杂志

ABSTRACT

Objective:To determine whether the immortalized human odo nt oblast-like cell line hTERT-hOd-l has transformed phenotype. Methods: The tumorigenicity, anchorage-independent growth, serum dependence and contact inhibition of the immortalized human odontoblast-like cell line hTERT- hOd-l were observed during continuous culture in vitro. Results: The cells showed to be nontumorigenic in nude mice, and to have no anchorag e-independent growth. The cells maintained the normal serum dependence and cont act inhibition. Conclusion:hTERT-hOd-l is a normal cell line w ithout obvious transformed phenotype.
