Chemical engineering of mesenchymal stem cells to induce a cell rolling response

Bioconjug Chem. 2008 Nov 19;19(11):2105-9. doi: 10.1021/bc800345q.

Abstract

Covalently conjugated sialyl Lewis X (SLeX) on the mesenchymal stem cell (MSC) surface through a biotin-streptavidin bridge imparts leukocyte-like rolling characteristics without altering the cell phenotype and the multilineage differentiation potential. We demonstrate that the conjugation of SLeX on the MSC surface is stable, versatile, and induces a robust rolling response on P-selectin coated substrates. These results indicate the potential to increase the targeting efficiency of any cell type to specific tissue.
