Abstract:

BACKGROUND: Human umbilical cord mesenchymal stem cells (hUC-MSCs) can secrete a variety of cytokines and growth factors to support hematopoiesis. They can change the hematopoietic microenvironment, and furthermore, regulate and improve the immune function of the organism.
OBJECTIVE: To investigate the effect of hUC-MSCs on immune reconstitution and prognosis in children with acute lymphoblastic leukemia (ALL) after allogeneic hematopoietic stem cell transplantation (allo-HSCT). 
METHODS: Sixty-four ALL children who had undergo allo-HSCT were enrolled and randomized into non-blood donor allo-HSCT group (n=32) and non-blood donor allo-HSCT+hUC-MSCs group (n=32). The therapeutic effect and complication were observed in the two groups. The changes of immunoglobulins and lymphocyte subpopulations in the two groups were compared before and 1, 3 and 6 months after transplantation. 
RESULTS AND CONCLUSION: Compared with the allo-HSCT group, the time of granulocyte implantation was shorter (P < 0.05), and the incidence of chronic graft versus host disease and cytomegalovirus was lower in the allo-HSCT+ hUC-MSCs group. There were no significant differences in hematopoietic stem cell implantation rate, platelet remodeling rate, cumulative recurrence rate and 1-year survival rate between the two groups (P > 0.05). The levels of serum immunoglobulins IgA, IgG, IgM, IgE and the levels of T lymphocytes (CD4+, CD3+CD4+, CD4+CD8+) and B cells in the peripheral blood of allo-HSCT+hUC-MSCs group were significantly higher than those in the allo-HSCT group at 1, 3 and 6 months after transplantation (P < 0.05). In conclusion, the combined use of hUC-MSCs infusion and allo-HSCT can effectively reduce the incidence of chronic graft-versus-host disease, and contribute to granulocyte hematopoietic reconstitution and immune function reconstruction.
