We describe the easy-to-use luminoscore method, based on precise acquisition conditions, requiring no calculations, and enabling tumor burden and treatment response to be monitored in mouse models.

A robust system for consistently and reliably obtaining these cells from the incisor and expanding them in vitro is reported here.
