Dock4^{tm1(NCOM)Mfgc}/Dock4⁺ embryos show an increase in the frequency of blood vessels with small lumen width and a decrease in the frequency of large lumen width in the brain

cardiovascular system

abnormal tumor vascularization ( J:224385 )

• following implantation of a syngeneic breast cancer cell line (EO771) into the striatum of 9-10 week old heterozygotes, tumors show a reduction in blood vessel lumen width with 21% of vessels having lumens of larger caliber (>35 um) relative to ~38% in control tumors

abnormal blood vessel lumen formation ( J:224385 )

• during developmental angiogenesis, E13.5 heterozygotes show only 9% of blood vessels with lumens of relatively large caliber (>20 um) in the brain parenchyma relative to ~31% in wild-type controls

• at E13.5, heterozygotes show a significant reduction in average blood vessel lumen width in the brain (15.1 um vs 18.6 um) relative to wild-type controls

• however, no differences in pericyte coverage of blood vessels are detected in the brain at E13.5

• no differences are detected in the lumen caliber of the aortas at E13.5

neoplasm

abnormal tumor vascularization ( J:224385 )

• following implantation of a syngeneic breast cancer cell line (EO771) into the striatum of 9-10 week old heterozygotes, tumors show a reduction in blood vessel lumen width with 21% of vessels having lumens of larger caliber (>35 um) relative to ~38% in control tumors
