Heparan Sulfate Mutant Mouse Lung Endothelial Cell Lines

Exostosin Ext1-deficeint (Ext1-/-) endothelial cell line was generated by transiently transduce the immortalized wildtype "mother" mouse lung endothelial cell line which harbors conditionally targeted Ext1 (Ext1f/f) followed by cell cloning.

Exostosin-1 is a protein that in humans is encoded by the EXT1 gene. This gene encodes an endoplasmic reticulum-resident type II transmembrane glycosyltransferase involved in the chain elongation step of heparan sulfate biosynthesis. Mutations in this gene cause the type I form of Multiple Exostoses.
