Are papillomaviruses routinely grown in laboratory cell cultures in vitro?

Papillomaviruses are not routinely grown in standard laboratory cell cultures in vitro, as they have a complex life cycle that requires specific types of host cells and conditions. While some progress has been made in establishing cultures for certain types of human papillomaviruses (HPVs), successful growth typically relies on specialized techniques and systems, such as organotypic cultures or keratinocyte cultures. Consequently, most research on papillomaviruses often utilizes alternative methods, such as molecular techniques or animal models, rather than routine cell culture.
