Pretreatment of 4LHBMEC with glycosaminoglycan (GAG)-degrading enzymes or sodium chlorate demonstrated that SDF-1 bound to both HSPGs and CS/DSPGs in a sulfation-dependent manner, as determined with an SDF-1 antibody recognizing the CXCR4-binding site. 4LHBMEC bound four-fold more SDF-1 than HUVEC.

In cultured RA ECs, exogenous CXCL12alpha was able to bind in a CXCR4-independent manner to surface HSPGs.
Desulfation of RA EC HSPGs by pretreatment with sodium chlorate, or by replacing in a synthetic CXCL12alpha the residues Lys24 and Lys27 by Ser (CXCL12alpha-K2427S), decreased or abrogated the ability of the chemokine to bind to RA ECs.
