更正：血管生成素-1受体Tie2区分牛尾椎髓核细胞的多能分化能力

Following publication of the original article in Stem Cell Research & Therapy [1], we would like to alert the reader that the immune-histological sections shown in Figure 2 bottom line are mistakenly the images from an experiment using a different Tie2+ antibody than originally reported in the manuscript (i.e. R&D, anti-human Tie2 labeled APC, cat.No:FAB3131A, clone:83715, mouse IgG) for the florescence associated cell sorting (FACS). This antibody has been previously tested in the group of Prof. Dr. Daisuke Sakai and was performed by Ms Tomoko Nakai, Tokai University. This antibody, however, was not found to be specific for bovine Tie2+ cells. The immune-histology procedure was correctly described using the PG antibody from Millipore. However, the pictures presented in Figure 2 in the last raw in the article of Tekari et al. [1] are not from the same experiment using the Tie2 antibody from Bioss, inc. clone bs-1300R, Bioss Antibodies, Woburn, MA, USA, as the publication reported.
