Determining donor cell engraftment presents a challenge in mouse bone marrow transplant models that lack well-defined phenotypical markers. We described a methodology to quantify male donor cell engraftment in female transplant recipient mice. This method can be used in all mouse strains for the study of HSC functions.

This video describes the technique of aspirating bone marrow from iliac spine and smear preparation for biopsy. In the example, we perform bone marrow aspiration from an acute myeloid leukemia (AML) patient and examine the cells to check for measurable residual disease (MRD), an important prognostic biomarker.

FAQs
Conditioning therapy prepares the recipient’s marrow before transplantation by creating space for incoming hematopoietic stem cells and suppressing existing marrow activity. These changes help the infused cells access marrow niches, specialized local environments where they can survive and establish themselves. Without this preparatory stage, the transplanted cells may have less opportunity to settle and begin restoring blood-cell production.
After migrating into marrow niches, transplanted hematopoietic stem cells must survive and establish a functioning cell population. They self-renew to maintain the stem-cell supply and differentiate into the major blood-cell lineages: red blood cells, white blood cells, and platelets. This coordinated activity allows recovery of hematopoiesis rather than producing only one type of circulating blood cell.
Delayed or failed bone marrow engraftment indicates that blood-cell production has not recovered adequately after transplantation. Because red blood cells, white blood cells, and platelets may remain insufficient, the recipient can face increased risks of infection, bleeding, and other complications. Engraftment therefore serves as a biologically meaningful milestone, not merely a laboratory observation, during transplant recovery.
Monitoring blood-cell counts provides evidence about whether the graft is beginning to function and hematopoiesis is recovering. Trends in red blood cells, white blood cells, and platelets help assess graft function, while reduced dependence on transfusions offers another practical indication of recovery. Together, these observations help distinguish improving engraftment from delayed or inadequate blood-cell production.
Engraftment marks the point at which transplanted hematopoietic stem cells have established themselves sufficiently to support renewed blood-cell production. In bone marrow and hematopoietic stem-cell transplantation, this milestone helps indicate whether the graft is functioning and whether dependence on transfusions is declining. It also provides a framework for evaluating recovery after conditioning and cell infusion.
Post-transplant evaluation focuses on restoration of the three principal blood-cell groups produced by marrow: red blood cells, white blood cells, and platelets. Researchers and clinicians can follow blood-cell counts to assess whether the transplanted cells are generating these lineages and whether graft function is improving. The findings also help identify delayed recovery associated with infection, bleeding, or other complications.
