Bone marrow cells were incubated in blind well chambers containing filters coated with the indicated substrates. After 1 hour at 37°C, the bottom of the filters and bottom wells were assayed for the presence of CFU-Es. The results are presented as the mean migration index ± SEM and the mean percent migration ± SEM (n = number of experiments).
