As presented in Table 1 (lower part), the pre-harvesting G-CSF levels were also significantly higher for myeloma patients (median 18,366 pg/mL; range 9861–46,314 pg/mL) than for the healthy stem cell donors (median: 10,780 pg/mL; range: 3687–31,947 pg/mL; p = 0.005). Here, CSF3 is linked to plasma cell myeloma.
