Adhesion of stem and progenitor cells to laminins in the presence of SDF-1α.

Adhesion of CD34⁺ (A), CD34⁺CD38⁻(B), and CD34⁺CD38⁺ cells to laminin-1 (LN-1), laminin-8 (LN-8), and laminin-10/11 (LN-10/11) in the presence of 300 ng/mL SDF-1α (dark columns) and without SDF-1α (light columns). The differences in cell adhesion in the presence or absence of SDF-1α were not significant (P > .05; LN-1, n = 3; LN-8, n = 9; LN-10/11, n = 12). Data are expressed as means ± SDs.
