Reducing Microbial Contamination in Hematopoietic Stem Cell Products and Quality Improvement Strategy: Retrospective Analysis of 1996-2021 Data.

Background: Sterility and safety assurance of hematopoietic stem cell (HSC) products is critical in transplantation. Microbial contamination can lead to product disposal and increases the risk of unsuccessful clinical outcomes. Therefore, it is important to implement and maintain good practice guidelines and regulations for the HSC collection and processing unit in each hospital.

Evaluation of a new cell separator for collection of peripheral blood CD34+ progenitor cells in pediatric patients.

Background: This study was conducted to evaluate the performance of the COM.TEC cell separator (Fresenius HemoCare GmbH) for collecting CD34+ cells in pediatric patients who were intended to have autologous peripheral blood progenitor cell transplantation, with respect to collection variables, prediction power of CD34+ cell yield, and influence on donors.

Study Design And Methods: A total of 26 pediatric solid tumor patients who received mobilization chemotherapy and granulocyte-colony-stimulating factor underwent CD34+ cell collection (n = 96) using the COM.
