title: Establishment of an immortal turkey turbinate cell line suitable for avian metapneumovirus propagation.
abstract: Until recently, there has not been a homologous avian cellular substrate which could continuously produce high titer avian metapneumovirus (AMPV); development of such a cell line should provide an excellent model system for studying AMPV infection. We have established a non-tumorigenic immortal turkey turbinate cell line (TT-1) to propagate sufficiently high AMPV titers. Currently, immortal TT-1 cells are growing continuously at 1.2-1.4 population doublings per day and are at passage 160. Kinetic analysis suggests that AMPV can infect and replicate more rapidly in TT-1 compared to Vero cells, although both cell types undergo apoptosis upon infection. The non-tumorigenic, reverse transcriptase negative TT-1 cell line can serve as an excellent homologous cellular substrate for virus propagation.
