In addition, other endothelial markers such as reduced soluble P‐selectin significantly correlated with prolonged thrombocytopenia and neutropenia (Figure 2C,H), reduced VEGF‐A with prolonged neutropenia and anemia (Figures 2D; S2F), and increased soluble VCAM‐1 (sVCAM‐1) with prolonged thrombocytopenia and anemia (Figure 2I,K). The gene discussed is VCAM1; the disease is anemia.
