CAM 5.2, AE1/AE3, GFAP, ACTIN, SMA, SMMHC, Caldesmon, CD3, CD10, CD20, CD21, CD34, CD45, Mac387, HMB45, MELANOMA CT were negative in all cell lines.
KI67 and P53 showed technical difficulties (TD) in all cell lines and therefore immunoreactivity could not be examined. Progesterone and CD15 showed TD with chondrocytes only but, were negative for other cell lines.
