Effect of Laryngeal Squamous Cell Carcinoma Tissue Implantation on the Chick Embryo Chorioallantoic Membrane: Morphometric Measurements and Vascularity

Figure 2

An immunohistochemical study of LSCC tissue before and after implantation on CAM. (a, c) The original tumor cells, which showed high positivity for the Ki67 (long arrows). (b) The original tumor cells (the same site as in (a)) were also positive for HMW CK (short arrows). (d) Endothelial cells of implanted tumor blood vessels were positive for CD31. (e, f) Ki67 positive nuclei of implanted LSCC cells. (a, b, d, and e) Bars 50 μm; original magnification 10x; (c, f) bars 20 μm; original magnification 40x.
