We have recently developed a strategy to identify novel candidate genes for MCDs and to directly confirm their causative role in vivo. Medicine Isolation of Human Lymphatic Endothelial Cells by Multi-parameter Fluorescence-activated Cell Sorting Zerina Lokmic1,2, Elizabeth S. Ng1,3, Matthew Burton1, Edouard G. Stanley1,2,3, Anthony J. Penington1,2, Andrew G. Elefanty1,2,3 1 The goal of this protocol is to isolate lymphatic endothelial cells lining human lymphatic malformation cyst-like vessels and foreskins using fluorescence-activated cell sorting (FACS). Subsequent cell culturing and expansion of these cells permits a new level of experimental sophistication for genetic, proteomic, functional and cell differentiation studies.

Here we demonstrate the use of an immunofluorescence assay for quantitation of γH2AX foci in tissue samples.
