Peripheral blood stem cells (PBSC) are used for transplantation to rec
onstitute the hematopoietic system after high-dose chemotherapy. PBSC
are harvested from peripheral blood upon successful mobilization by cy
tokines and/or chemotherapy. Further in vitro manipulation steps like
enrichment of CD34(+) PBSC or gene transfer can be performed. To ensur
e the quality and safety of the final cell preparations intended for t
ransplantation, national and international guidelines and regulations
have been issued. Herein the implementation of a quality assurance pro
gram including the principles of good manufacturing practice (GMP) and
a quality control (QC) system is one major concern, GMP regulations a
pply to all phases of cell collection, processing and storage as well
as documentation, training of personnel, and the laboratory facility.
QC measures have to be taken to ensure consistent quality and safety w
ith an emphasis on preventing any deficiencies.
