Preclinical Evaluation of the Immunomodulatory Properties of Cardiac Adipose Tissue Progenitor Cells Using Umbilical Cord Blood Mesenchymal Stem Cells: A Direct Comparative Study

Figure 3

Formation of T cell proliferation clusters is affected by increasing numbers of cardiac ATDPCs in the allostimulatory assay. Representative phase-contrast images of 1,250 and 20,000 cardiac ATDPCs (white arrows) cocultured along with T cells (red arrows) and allogeneic mature MDDCs (black arrows) at 1 and 4.5 days. Red asterisks indicate T cell proliferation clusters at 4.5 days. Similar images were taken from UCBMSC cocultures. Scale bars = 100 μm.
