Abstract

This study was aimed to explore the factors impacting on effect of the recombinant human granulocyte colony-stimulating factor (rhG-CSF) in mobilizing and collecting peripheral blood stem/progenitor cells (PBSPC) from healthy donors, and to determine the optimal time for PBSPC harvest. A mobilization course in 431 healthy donors was retrospectively studied and the factors influencing the efficacy of mobilization were analyzed. The normal donors underwent leukapheresis for PBSPC collection in multicentres after mobilization with G-CSF administered. A variety of items analyzed included donor age, sex, weight, body mass index (BMI), daily G-CSF dose and schedule of G-CSF administration. The results showed that G-CSF was administered subcutaneously at median 5.7 microg/kg for mobilization for 3 - 5 days, The median number of peripheral blood mononuclear cells (PBMNC) count of per kg recipient weight was 9.57 x 10(8) and CD34(+) cells per kg recipient weight was 4.91 x 10(6) after a median of 1.7 leukapheresis. The side effects were mild and well tolerated. By univariate analysis, BMI, daily G-CSF dose and schedule of administration were significantly correlated with the yield of PBMNCs, CD34(+) cells. The best apheresis yields of P...Continue Reading

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.
