Core Tip

Core Tip: This cohort study evaluates the safety and efficacy of recombinant human thrombopoietin (rhTPO) in pediatric allogeneic hematopoietic stem cell transplantation. The findings suggest that rhTPO promotes earlier platelet engraftment, particularly in younger children aged 0-9 years. This age-dependent response highlights the influence of developmental hematopoiesis on treatment outcomes. Despite the limitations of a single-center, non-randomized design, the study provides novel insights that support rhTPO as a promising supportive therapy in pediatric allogeneic hematopoietic stem cell transplantation and underscores the need for age-specific post-transplant strategies.
