3. Sources of stem cells
Case Report
Mobilization schedule for autologous donor
4. Stem Cell Sources
Bone Marrow Harvest (BM)
Peripheral Blood Stem Cell (PBSC)
Umbilical Cord Blood
5. Which is best? Multi-center study recently completed by NMDP comparing PBSC to BM.
- # days to engraftment
Amount of Graft Vs. Host disease (GVHD)
Disease recurrence.
Results pending
6. Who Decides? Decision regarding source:
Related donors = physician decides (at our center last year in adults 100% PBSC)
Unrelated donors = physician requests product but donor can decide to accommodate that request or not.
7. Bone Marrow Harvest Used to be standard procedure for harvesting stem cells
Requires general anesthesia
Multiple needle punctures into the Posterior iliac crest to extract liquid bone marrow
Amount harvested depends on size of recipient, usually no more than 2% of donor marrow.
Used mostly with pediatric population rarely for adult donors.
8. Umbilical Cord Blood Advantages:
Rich source of haemopoeitic stem and progenitor cells.
Contains more naive T-cells than bone marrow which allows for a greater mis- match without increased risk of GVHD
No risk to donors
Decreased risk of infection
Easily obtained
9. Umbilical Cord Blood Disadvantages
Definitive number of cells. Can not request more from donor
Longer time to engraftment.
Often time total cell count (TCN) not enough for adult.
10. Obtaining Cord Blood Unsuccessful unrelated search.
Search Cord Blood Banks through the NMDP.
Often times request 2 cords to increase TNC.
Usually attempt to find 5/6 HLA match cords.
Cords shipped to our facility once patient is ready for transplant, but before prep regimen is started (if shipped and not used cannot be returned and we incur expense)
12. Peripheral Blood Stem Cells Most frequent way for obtaining stem cells.
Does not require general anesthesis
Decrease risk to donor
Quicker time to engraftment than BM.
13. Related donors Initial visit to Bone Marrow Transplant Clinic for testing to determine eligibility.
Starting on Friday donor begins Growth Colony Stimulating Factor (GCSF) 10 mcg/kg sub-q daily.
Saturday and Sunday GCSF injection.
Monday begin PBSC.
Usually collect enough in one day, sometimes requires another collection.
14. Medications Growth Colony Stimulating Factor Most commonly used agent to mobilize stem cells.
Hormone that stimulates the bone marrow to produce hematopoietic cells.
Side Effects:
Bone pain
Headache
Nausea
Local reaction at injection site
15. Medications Plerixafor Given with GCSF, binds with protein on the surface of the stem cell disrupting the bond that normally keeps the stem cell anchored in the bone marrow.
.24 mg/kg sub-q at 9:00 PM
Side effects generally well tolerated.
Diarrhea
nausea
tiredness,
Injection site reactions
Headache
Joint pain
dizziness

Following your injection this morning if your counts are adequate you will be directed to the Apheresis Unit, Gateway Building 6th floor to begin the stem cell collection. The labs take approximately 2 hours to result. If your counts are not adequate with neupogen alone we will add **mozobil injection that evening. You will be advised of your lab results and the plan. If you come back that night for mozobil Tuesday morning you will go directly to the apheresis unit at 8:00 AM. Apheresis takes 3-5 hours. Please eat breakfast before the procedure. If you start mozobil these injections will be continued each night along with apheresis the following morning until we have collected an adequate number of cells for transplant.

Lab work
Neupogen injections
Tums, Bactrim, and Levaquin
8:00PM North Hospital 10th floor
Inpatient Bone Marrow Transplant Unit
Mozobil injection
This will continue daily until we have collected enough stem cells
21. Goals for collection Single Transplant 5 X 10(6) stem cells
Tandem Transplant 10 X 10(6) stem cells
This is counted daily at the end of collection which will determine if the patient continues with apheresis the next day.
