A Integrin expression: Flow-cytometry analysis revealed predominant ex- pression of β1-, β4-, as well as α1-, α2-, α3- α6- and αv- integrins on HT-29 LMM cells. Only weak expression of α5-integrins; α4-integrins are not expressed. B Glycoprotein expression: E-Selectin binding sLe-a was found on HT-29LMM in the absence of sLe-x. TF-antigen and galectin-3 are both present for endothelial cell binding.
