ZO-1 Regulates the Migration of Mesenchymal Stem Cells in Cooperation with α-Catenin in Response to Breast Tumor Cells

Scientists identified zonula occludens-1 (ZO-1) as a specific intrinsic molecule that plays a vital role in mediating the collective migration of MSCs towards breast tumor cells and transforming growth factor beta, which was a crucial factor secreted by breast tumor cells.
