Xin Zhao, Xingmin Feng, Zhijie Wu, Thomas Winkler, Ronan Desmond, Matthew Olnes, Bogdan Dumitriu, Danielle M. Townsley, Cynthia E. Dunbar, Neal S. Young  Experimental Hematology  Volume 58, Pages (February 2018) DOI: /j.exphem Copyright © Terms and Conditions

2 Figure 1 Longitudinal plasma EPO and G-CSF levels in severe AA patients. (A) EPO and G-CSF levels in treatment-naive patients (n = 37). Blue circles represent responders; red circles represent nonresponders. *p < 0.05; **p < 0.01; ***p <  (B) Follow-up of EPO levels and hemoglobin concentrations in complete responders to IST (n = 9). (C) Correlation of plasma EPO levels with hemoglobin concentrations in severe AA patients. (D) EPO and G-CSF levels in IST-refractory patients (n = 10). Error bar indicates mean and SEM for hemoglobin levels in (B) and median and interquartile in others. Experimental Hematology  , 39-43DOI: ( /j.exphem ) Copyright © Terms and Conditions

3 Figure 2 Changes in plasma TPO levels over time in severe AA patients. TPO levels in treatment-naive (A) and IST-refractory patients (B). Blue circles represent responders; red circles represent nonresponders. *p < 0.05; **p < 0.01; ***p <  (C) Different levels of plasma TPO between severe AA patients (n = 10) and healthy donors (n = 8) validated by Western blotting (TPO antibody from Thermo Fisher Scientific). The intensities of bands were quantified and depicted in the bar graph. (D) Follow-up of TPO levels and platelet counts in complete responders to IST (n = 9). (E) Correlation of plasma TPO levels with platelet counts. Red dots and black dots represent complete responders and nonresponders from treatment-naive group, respectively; blue dots represent IST-refractory patients; green dots represent healthy controls. Dots within the square were compared for TPO levels between patients and healthy controls. Patient's samples from different time points at baseline and after treatment were all included in this figure. Error bar indicates mean and SEM for platelet count in (D) and median and interquartile in others. Experimental Hematology  , 39-43DOI: ( /j.exphem ) Copyright © Terms and Conditions
