Fig. 4From: Suppression of TGFβR-Smad3 pathway alleviates the syrinx induced by syringomyeliaTNFα and BDNF expression under syringomyelia. A TNFα and BDNF were expressed in central canal. DAPI, blue; TNFα and BDNF, green; GFAP, red. Scale bars: 100 μm. B BDNF receptor TrkB was not expressed by central canal, whether decompression or not. DAPI, blue; TrkB and BDNF, green; GFAP, red.
