Recruitment Details
| Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations |
|---|
| Healthy adult donors were recruited at three blood collection centers to undergo a mononuclear cell collection using the experimental device, between January and September, 2011. |

Reporting Groups
| Description | |
|---|---|
| G-CSF Mobilized Donors | In this arm the donors received G-CSF (granulocyte colony stimulating factor) prior to the MNC (mononuclear cell) collection. G-CSF causes the mobilization of hematopoetic stem cells which are CD34 (cluster of differentiation 34) + to the peripheral blood. Collection efficiency of all mononuclear cells and of the CD34+ subset of mononuclear cells was assessed. |
| Non-mobilized Donors | In this arm, donors were not mobilized prior to mononuclear cell collection. Only collection efficiency of mononuclear cells could be assessed as CD34+ cells are not present in this population. |
