Fluorescence-activated cell sorting of larval zebrafish muscle stem/progenitor cells following skeletal muscle injury

Abstract

This chapter describes a protocol for the isolation of larval zebrafish muscle stem/progenitor cells by fluorescence-activated cell sorting (FACS). This method has been successfully applied to isolate pax3a expressing cells 3 days following needle stab skeletal muscle injury. The cell sorting strategy described here can easily be adapted to any cell type at embryonic or larval stages. RNA extracted from the sorted cells can be used for subsequent downstream applications such as quantitative PCR (qPCR), microarrays, or next generation sequencing.
