Top: Examples of the fields of view of transwell membranes, showing the stained MSC cells that migrated to the lower membrane side of transwells when the upper compartment contained control serum (left) and serum from rats subjected to recurrent obstructive apneas (right). Serum of control rats was placed in the lower transwell compartment in both cases. Bottom: Normalized indices for the migration of mesenchymal stem cells induced by the serum of control and apneic rats. Data are mean ± SEM. NS: non-significant (p > 0.05).
