In the paper titled “Characterization of Bone Marrow Mononuclear Cells on Biomaterials for Bone Tissue Engineering In Vitro,” [1] there was an error in the Acknowledgments. The changes made to the Acknowledgments are as follows. The AO-Research Foundation and the respective Grant no. S-11-64-N were added since the AO provided financial support to this study. Therefore the Acknowledgments was changed as follows:

“This work was partially founded by the German Institute for Cell and Tissue Replacement gGmbH (DIZG), Berlin, the LOEWE Center for Cell and Gene Therapy Frankfurt funded by Hessian Ministry of Higher Education, Research and the Arts (funding reference no. III L 4-518/17.004 (2010)), and the AO-Research Fund, Davos, Switzerland (funding reference no. S-11-64-N).”
