Mononuclear tetraploid content distinguishes rodent cardiac stem cells in vitro. G-band karyotype analysis performed upon cultured CSCs reveals tetraploid content of rodent mouse (a) and rat (b) in contrast to diploid content of swine (c) and human (d) samples. Immunocytochemistry of CSC verifies mononuclear content of karyotyped cells (scalebar = 500 μm) (eh) and zoomed-in images (scalebar = 100 μm) (e′–h′). Multiple samples from different CSC lines verify consistent tetraploid content in adult mouse (i) and rat (j) CSCs, while swine (k) and human (l) CSCs are consistently diploid. Cell counts included in flow-cytometry analysis provided in parenthesis
