Area of Science:

  • Hematology
  • Biotechnology
  • Medical Devices

Background:

  • Autologous bone marrow processing is essential for transplantation.
  • Current methods may lack standardization and efficiency.
  • Ex vivo manipulation and cryopreservation require reliable starting material.

Purpose of the Study:

  • To develop a semiautomated bone marrow processing procedure.
  • To optimize cell recovery and red cell removal.
  • To establish a standardized protocol for bone marrow transplantation.

Main Methods:

  • Utilized a pediatric Latham bowl (125 ml).
  • Employed the automated DuPont Stericell processor.
  • Developed a semiautomated processing workflow.

Main Results:

  • Achieved 85% mononuclear cell recovery.
  • Obtained 81% hemopoietic progenitor cell recovery (CFU-GM, BFU-E).
  • Reached 84% red cell removal efficiency.

Conclusions:

  • The developed procedure is reliable and standardized.
  • High cell recovery and red cell reduction are demonstrated.
  • This method is a fundamental requirement for bone marrow transplantation programs.
