Abstract
Continuous growth of the rodent incisor is enabled by epithelial and mesenchymal stem cells (ESCs and MSCs) which unceasingly replenish enamel and dentin, respectively, that wear by persistent animal gnawing. Lineage tracing studies have provided evidence that ESCs contribute to all epithelial lineages of the tooth in vivo. Meanwhile, in the mouse incisor, MSCs continuously contribute to odontoblast lineage and tooth growth. However, in vitro manipulation of ESCs has shown little progress, mainly due to lack of appropriate protocol to successfully isolate, culture, expand, and differentiate ESCs in vitro without using the co-culture system. In this chapter we describe the isolation of the Sox2-GFP+ cell population that is highly enriched in ESCs. Isolated cells can be used for various types of analyses, including in vitro culture, single cell-related analyses, etc. Furthermore, we describe ways to obtain populations enriched in the incisor MSCs using FACS sorting of antibody-labeled cells. Easily accessible FACS sorting enables easy and relatively fast isolation of the cells labeled by the fluorescent protein.
