    Summary

    Graft engineering for allogeneic hematopoietic stem cell transplantation (HSCT) aims to improve engraftment and reduce GVHD and relapse. Umbilical cord blood banking quality and clinical efficacy are crucial, with autologous banking being largely ineffective.

    Area of Science:

    • Hematology
    • Transplantation Immunology
    • Regenerative Medicine

    Background:

    • Allogeneic hematopoietic stem cell transplantation (HSCT) is a vital treatment for various diseases.
    • Current HSCT faces challenges including low engraftment, graft-versus-host disease (GVHD), and relapse.
    • Graft engineering and ex vivo stem cell modification offer promising solutions.

    Purpose of the Study:

    • To highlight the significance of graft engineering in HSCT.
    • To discuss the evolving role of cell therapy in treating malignancies.
    • To evaluate the current state and future directions of umbilical cord blood banking (CBB) and transplantation (CBT).

    Main Methods:

    • Review of current research in HSCT and graft engineering.
    • Analysis of the benefits and limitations of umbilical cord blood banking.
    • Evaluation of the efficacy of autologous versus allogeneic cord blood transplants.

    Main Results:

    • Graft engineering is key to overcoming HSCT limitations.
    • Combining HSCT with gene and immune therapy represents a novel cytotherapy approach.
    • High cord blood collection rates in China contrast with low clinical application due to infrastructure and expertise gaps.
    • Emphasis on release rates and clinical efficacy is vital for CBB evaluation.
    • Autologous cord blood banking is deemed ineffective for inherited diseases and questionable for malignancies.

    Conclusions:

    • Tailor-made grafts through ex vivo engineering are crucial for advancing HSCT.
    • The clinical utility of cord blood banks depends on release rates and demonstrated efficacy.
    • Autologous cord blood banking is not recommended due to lack of proven benefits and potential risks.
