  1. Nishikubo N, Takahashi J, Roos A, Derba Maceluch M, Piens K, Brumer H, et al. Xyloglucan endo-transglycosylase-mediated xyloglucan rearrangements in developing wood of hybrid aspen. Plant Physiol. 2011;155:399-413 pubmed publisher

    ..The arabinose to xylose ratio was low (approximately 0.2) and no 2,3-disubstitution existed. No blocks of substituted xylose residues could be observed along the main chain. ..
  7. Bodin A, Ahrenstedt L, Fink H, Brumer H, Risberg B, Gatenholm P. Modification of nanocellulose with a xyloglucan-RGD conjugate enhances adhesion and proliferation of endothelial cells: implications for tissue engineering. Biomacromolecules. 2007;8:3697-704 pubmed
    ..Optimization and proliferation studies of human endothelial cells onto bacterial cellulose modified with XG-GRGDS are currently being carried out at the Vascular Engineering Center, Sahlgrenska University Hospital, Gothenburg. ..

  9. Mellerowicz E, Immerzeel P, Hayashi T. Xyloglucan: the molecular muscle of trees. Ann Bot. 2008;102:659-65 pubmed publisher
    ..It is postulated that these activities are essential for generation of tensile stress during fibre maturation in tension wood. ..
