The Roles of Podoplanin-Positive/Podoplanin-Negative Cells from Adipose-Derived Stem Cells in Lymphatic Regeneration

Abstract

These data demonstrated that actions by means of both paracrine and differentiation pathways were involved in the adipose-derived stem cell-mediated therapeutic effects. The podoplanin-positive cells possessed lymphatic paracrine and differentiation abilities and may represent lymphatic endothelial cell precursor cells. The podoplanin-negative cells, which constitute a considerable proportion of the adipose-derived stem cells, may play an important paracrine role by secreting mesenchymal stem cell-related factors.
