Erratum to: In Vitro Cell. Dev. Biol. -Animal DOI 10.1007/s11626-015-9885-z Publ Vol 51 No 7 pp. 714–721 In the caption for Fig. 6, and in the text on page 720 (left-hand column, 2nd paragraph, 3rd line from bottom), the terms “vimentin” and “pan-cytokeratin” need to be exchanged as illustrated in the following text: Original text ... Immunohistochemical analysis showed expression of vimentin (d) with strong coexpression of pan-cytokeratin (e) in part of the tumor cell population. … Immunohistochemically, the tumor cells were positive for vimentin with strong coexpression of pancytokeratin in part of the cell population (Fig. 6d, e). Revised text ...Immunohistochemical analysis showed expression of pancytokeratin (d) with strong coexpression of vimentin (e) in part of the tumor cell population. … Immunohistochemically, the tumor cells were positive for pan-cytokeratin with strong coexpression of vimentin in part of the cell population (Fig. 6d, e). The authors regret the error.
