Quantifying Leukocyte Egress via Lymphatic Vessels from Murine Skin and Tumors

Here, we demonstrate the methods for in vivo quantification of leukocyte egress from naïve, inflamed, and malignant murine skin. We perform a head-to-head comparison of two models: transdermal FITC application and in situ photoconversion. Furthermore, we demonstrate the utility of photoconversion for tracking leukocyte egress from cutaneous tumors.
