Expression of TrkA in synovial membranes from two horses with intracarpal fractures representing different nuclear staining patterns. (A) Synoviocytes with abundant intranuclear staining (arrows) and cytoplasmic staining only (arrowhead). (B) Synoviocytes with cytoplasmic staining only. In both (A) and (B) there is a marked extracellular matrix staining (asterisks). Total synovitis score for the two horses were 9 (left) and 8 (right) (×40, scale bar: 50 µm). BAX, Bcl‐2‐Associated X protein; p75NTR, pan‐neurotrophin receptor;TrkA, tyrosine kinase A
