Isolation and Fluorescence-Activated Cell Sorting of Mouse Keratinocytes Expressing β-Galactosidase

Part of the Methods in Molecular Biology book series (MIMB,volume 1453)

Abstract

During the past decade, the rapid development of new transgenic and knock-in mouse models has propelled epidermal stem-cell research into “fast-forward mode”. It has become possible to identify and visualize defined cell populations during normal tissue maintenance, and to follow their progeny during the processes of homeostasis, wound repair, and tumorigenesis. Moreover, these cells can be isolated using specific labels, and characterized in detail using an array of molecular and cell biology approaches. The bacterial enzyme, β-galactosidase (β-gal), the product of the LacZ gene, is one of the most commonly used in vivo cell labels in genetically-engineered mice. The protocol described in this chapter provides a guideline for the isolation of viable murine epidermal cells expressing β-gal, which can then be subjected to further characterization in vivo or in vitro.
