Human Skin Explant Preparation and Culture.

The ex vivo experimentation with surgically discarded human skin represents a unique methodology amenable for mechanism and pharmacologic agent studies without the involvement of human subjects. Here, we describe a protocol that includes preparation, culture, and stimulation of human skin explants, and subsequent analyses by quantitative reverse transcription PCR and immunostaining. This protocol may also be applied for ex vivo studies of murine skin, reducing animal numbers and potentially harmful treatments. In our hands, this protocol has been used for wound healing, viral infection, and hair growth-related studies. Graphical abstract: Cartoon of explant skin culture.
