Fig. 1From: Arsenic trioxide induces cell cycle arrest and affects Trk receptor expression in human neuroblastoma SK-N-SH cellsTrk expression in neuroblastoma pathological tissue. Immunohistochemical analyses of TrkA, TrkB TrkC expression. Immunoreactive labeling for TrkA (a), TrkB (c) and TrkC (e) was observed in the cytoplasm of NB cells. In the control cells, TrkA (b), TrkB (d) and TrkC (f) expression was observed. Original magnification ×200. Bar 100 µmBack to article page
