In vitro infection of normal human keratinocytes by human papillomavirus type 1 followed by amplification of the viral genome in reconstructed epidermis.
Primary cultures of normal human keratinocytes were inoculated in vitro with human papillomavirus type 1 (HPV-1), the agent responsible for deep plantar warts. Upon transfer to dead de-epidermized dermis and growth at the air-liquid interface, keratinocytes reconstituted a pseudoepidermis. Under these highly differentiating conditions, HPV-1 DNA amplification was found to take place in the reconstructed epidermis, being detectable from 7 days after the transfer and persisting for at least 10 days thereafter. The extent of keratinocyte differentiation may be insufficient to allow a complete HPV infectious cycle.
