ABSTRACT
Objective To construct tissue microarray with astrocytic tumor microvessels(AstMV) of human brain and investigate astrocytic tumor angiogenesis.Methods Thirty-six specimens containing different microvessels from 200 specimens were selected as donor blocks,which was followed by punching,sampling and seeding samples with tissue microarray apparatus.The tissue microarrays were used to detect the expression of CD34,FⅧ-RAg and CD105.Results Tissue microarray of AstMV was successfully constructed and an instrument for location was made.CD34,FⅧ-RAg and CD105 were expressed on endothelial cell membrane or(and) plasma.There were difference in microvessel number between astrocytic tumors and between endothelial markers.In the gradeⅡ,Ⅲ and Ⅳ astrocytomas,microvessels labeled by CD34 and FⅧ-RAg antibodies were more than those detected by CD105 antibody.There were number difference in microvessels labeled by CD34 and FⅧ-RAg antibodies between grade Ⅰ and gradeⅡ,Ⅲ and Ⅳ tumors.Conclusion Construction of tissue microarray containing different tumor microvessels might be of significance in evaluating tumor angiogenesis.This study may be the basis for constructing digital tumor microvessel models and exploring the mathematic relation between astrocytic tumor microvessels and vascular growth factors.
