Investigation of the Species Origin of the St. Jude Porcine Lung Epithelial Cell Line (SJPL) Made Available to Researchers

The SJPL cell line was reported and described as an immortalized porcine lung epithelial cell line suitable for influenza virus replication by Seo et al. (5) and has been available to researchers through ATCC (American Type Culture Collection) cell depositary services (deposit date, 5 April 2001; assigned accession number, PTA-3256) following a material transfer agreement. Recent findings indicate that the SJPL cell line is not of porcine origin but is more likely of monkey origin.
