====== Lentiviral transduction ======


[[Lentiviral]] [[transduction]] is an efficient method for the delivery of [[transgene]]s to mammalian cells and unifies the ease of use and speed of transient [[transfection]] with the robust expression of stable [[cell line]]s.

Uhlmann et al. from the [[University Hospital of Düsseldorf]], described a [[protocol]] for the alteration of [[gene expression]] in [[human induced pluripotent stem cell]]s (hiPSCs) via [[overexpression]] of a mutant form of the [[TP53]] ([[R249S]]) gene using [[lentiviral transduction]]. A high amount of TP53 protein is detected 1 week after transduction and [[antibiotic]] selection. Differentiation of transduced hiPSCs gives insight into a better understanding of cancer formation in different tissues and may be a useful tool for genetic or pharmacologic screening assays.
