Identification of cultured myoepithelial cells (MECs). Immunofluorescence experiments were performed with sections of wild-type (WT) mouse lacrimal glands (LG) and cultured WT and thrombospondin 1 null (TSP1^−/−, alias Thbs1^−/−) MECs using α-smooth muscle actin (α-SMA, shown in green) and cytokeratin 14 (CK14, shown in red) in the top panels and p63 (shown in red) in the bottom panels. Nuclei are stained with DAPI (blue). n = 3 independent experiments. Scale bars = 10 μm. Original magnification, ×200 (unless otherwise indicated).
