Genetic Modification of Human Primary Keratinocytes by Lentiviral Vectors

Keratinocytes are hard to transfect. Viral vectors are a good alternative to genetically modify primary keratinocytes. A classical method is the use of retroviral vectors by co-culture of keratinocytes with virus-producer cells. This method is efficient in high-calcium conditions with feeder cells. However, sometimes co-culture is not possible and is more laborious as producer cells need to be replaced by feeder cells. Our solution is the use of lentiviral vectors, far more efficient as supernatant on keratinocytes. In this chapter we describe improved detailed protocols for stable genetic modification of human primary keratinocytes of the skin or head and neck, in both low- and high-calcium conditions by lentiviral vectors.
