Intervention / TreatmentIntervention / Treatment |
|---|---|
|
Non-mobilized donors
In this arm the collection efficiency of mononuclear cells from non-mobilized donors will be studied.
|
Each donor will undergo one apheresis procedure to collect mononuclear cells from their peripheral blood.
|
|
G-CSF mobilized donors
In this arm the collection efficiency of CD34+ cells will be studied.
|
Each donor will undergo one apheresis procedure to collect mononuclear cells from their peripheral blood.

Primary Outcome Measures
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
Mononuclear Cell Collection Efficiency
Time Frame: One day
|
The collection efficiency for a given cell type is defined as the percent of processed cells of that cell type that are in fact collected.
|
One day
|
|
CD34+ Cell Collection Efficiency
Time Frame: one day
|
The collection efficiency for CD34+ cells is defined as the percent of processed CD34+ cells that were in fact collected.

Secondary Outcome Measures
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
Platelet Collection Efficiency
Time Frame: One Day
|
Platelet contamination of the cell product was measured as the platelet collection efficiency, that is, as the percent of platelets processed that were collected.
|
One Day
|
|
Hematocrit of MNC Product
Time Frame: One Day
|
The hematocrit of the collected product was used to quantitate RBC (red blood cell) contamination.
|
One Day
|
|
Granulocyte % of MNC Product
Time Frame: One day
|
Granulocyte contamination of the MNC product was quantitated as the percent of total product WBC (white blood cell) that were segmented granulocytes or bands.
|
One day
|
|
Viability of the Collected MNC Product
Time Frame: One day
|
The viability of the collected white blood cells was assessed using the 7-AAD (7-amino actinomycin D) viability dye in a flow cytometric assay.
Viability assessment is incorporated into the CD34 assay.
This assay was only performed on G-CSF mobilized donors as nonmobilized donor have too few CD34+ cells to detect.
Thus viability of the collected WBCs is reported only for the G-CSF mobilized arm.
