The failure to detect XMRV in re-extracted archival material from the VP62 sample and lack of sequence diversity among the XMRV VP35, VP42, and VP62 consensus genomes raised the possibility of contamination of the prostate cancer samples in the 2006 Urisman, et al. study by a laboratory - derived cell line, either known to be infected with XMRV, such as 22Rv1 [35], [38], or capable of supporting XMRV infection and potentially infected, such as LNCaP [43], [48].
