Immunocytochemical localization of stem cell and lineage specific proteins (green) in QD labeled (red) stem cells. QD labeled cells stained positive for nuclear (Ki67, Nanog, Nucleostemin, GATA-4), secretory (Amylase), and filamentous proteins (Nestin, α-SMA, Neurofilaments) indicating spontaneous in vitro differentiation. Nuclei were stained with DAPI (blue).
