Figure 3.

Felty syndrome patients show STAT3 phosphorylation in bone marrow. Representative immunohistochemical analysis of phospho-Tyr705-STAT3 (red) and CD57 (green) in bone marrow tissue samples of Felty syndrome (n=7) and control samples (n=14) counterstained with hematoxylin. All images presented in the figure are 40× magnified unless otherwise specified. Felty syndrome patients show more phosphorylated STAT3 than controls, but the amount of phosphorylation was not related to the STAT3 mutation VAFs. Patient numbers and mutation status are presented in the figure.
