This study investigates the factors affecting the homing of hematopoietic stem cells (HSCs) in bone marrow (BM) donors of acute lymphoblastic leukemia (ALL) patients after granulocyte colony-stimulating factor (G-CSF) injection, as well as the effects of G-CSF on BM transplantation quality in these patients. The results show that G-CSF increases the level of CD34+ HSCs and alters the expression of homing factors, leading to improved BM transplantation quality in ALL patients.
Hematopoietic stem cells (HSCs) transplantation is considered a suitable treatment for malignant or nonmalignant hematological diseases. This study aims to investigate the HSCs homing factors in bone marrow (BM) donors of acute lymphoblastic leukemia (ALL) patients following granulocyte colony-stimulating factor (G-CSF) injection, as well as the G-CSF effects on BM transplantation quality in these patients. To mobilize HSCs into peripheral blood, G-CSF was used for ALL patient's BM donors. For HSCs counting, CD34+ cells were evaluated in analogous and autologous donors using flow cytometry. The expression of stem cell homing factors in CD34+ cells and peripheral blood mononuclear cells (PBMCs) were investigated using a real-time polymerase chain reaction. Finally, hematological factors after BM transplantation in ALL patients were assessed. According to our results, after G-CSF injection, the level of CD34+ HSCs was statistically increased. Besides, autologous donors showed a higher level of CD34+ cells compared to analogous donors before and after G-CSF injection. Additionally, a higher number of CD34+ HSCs was achieved in the autologous samples following G-CSF injection. Furthermore, after G-CSF injection, the expression of matrix metalloproteinase (MMP)-2, MMP-9 was increased; while, stromal cell-derived factor 1, intercellular adhesion molecule-1, and vascular cell adhesion molecule-1 expression were decreased. Moreover, the expression of C-X-C chemokine receptor type 4, lymphocyte function-associated antigen 1, and very late antigen-4 in CD34+ cells and PBMCs were decreased. BM transplantation on Day 90 also caused an increased level of white blood cells, red blood cells, and platelets as compared to the first day; however, no statistical differences were observed in hemoglobin level. In conclusion, G-CSF by altering the expression of HSCs homing factors in ALL donors improves BM transplantation quality in ALL patients.
