  • Title: Thrombospondin and a 140 kd fragment promote adhesion and neurite outgrowth from embryonic central and peripheral neurons and from PC12 cells.
    Author: O'Shea KS, Liu LH, Dixit VM.
    Journal: Neuron; 1991 Aug; 7(2):231-7. PubMed ID: 1873028.
    Abstract:
    The ability of thrombospondin (TSP), an extracellular matrix glycoprotein, and two proteolytic fragments to support adhesion and neurite outgrowth from embryonic dorsal root ganglia, spinal cord neurons, and PC12 cells was examined. Anti-TSP antibodies or a synthetic peptide (GRGDS) containing an RGD cell-binding region was also added to cells plated on TSP. TSP and its 140 kd fragment were more efficient than laminin controls in supporting adhesion. Neurites formed on laminin, on varying concentrations of TSP, and particularly the 140 kd fragment. The amino-terminal heparin-binding domain supported little adhesion and outgrowth. Both adhesion and process outgrowth on TSP were inhibited by addition of anti-TSP antibodies, but not GRGDS.
