It is a special procedure by which we selectively collect stem cells and use it in bone marrow transplantation for the treatment of leukemia, lymphomas, multiple myeloma etc. Stem cells the mononuclear cells (monocytes and lymphocytes). The stem cells donor can be the patient himself (Autologus donor) or a HLA matched donor (Allergenic donor). The donor is given Filgrastim injection.10 ugm/kg/day for four days and on the fifth day peripheral blood stem cells are collected. A biovalve cannula is inserted in to the subclavian vein under L.A. with all aseptic precautions to one valve the return tubing is attached through which remaining blood minus the stem cells is passed back into the donor to the other valve inlet tubing is attached through which blood is collected and processed in the cell separator.

In the year 2004 Twenty two stem cell Apheresis procedures were carried out in Jaslok Hospital under the Transfusion Medicine Department and Hemato Oncology Department, Two hundred and eight platelet Apheresis procedures were carried out in Transfusion Medicine Department.
