Vascular endothelial cell growth inhibitor of normal and pathologic human vitreous
B. Jacobson, P. K. Basu and S. M. Hasany
Normal and pathologic human vitreous have been analyzed for the presence of
a low-molecular weight inhibitor of aortic endothelial cell proliferation.
Vitreous was subjected to gel chromatography and the material appearing in
the retarded volume (less than 13,000 daltons) was tested for its ability
to inhibit tritiated thymidine incorporation into DNA by calf aortic
endothelial cells. Depending on the sample of vitreous analyzed, one or
more fractions showing inhibitory activity were identified in each case.
