Isolation of skin-derived precursors (skps) and differentiation and enrichment of their schwann cell progeny

Play all audios:


ABSTRACT This protocol describes methods of isolating skin-derived precursors (SKPs) from rodent and human skin, and for generating and enriching Schwann cells from rodent SKPs. SKPs are


isolated as a population of non-adherent cells from the dermis that proliferate and self-renew as floating spheres in response to fibroblast growth factor 2 (FGF2) and epidermal growth


factor (EGF). Their differentiation into Schwann cells and subsequent enrichment of these differentiated progeny involves culturing SKPs as adherent cells in the absence of FGF2 and EGF, but


in the presence of neuregulins, and then mechanically isolating the Schwann cell colonies using cloning cylinders. Methods for expanding and characterizing these Schwann cells are provided.


Generation of primary SKPs takes approximately 2 weeks, while differentiation of Schwann cells requires an additional 4–6 weeks. Access through your institution Buy or subscribe This is a
