Apheresis Collection for New Drug Development and Evaluation Research

Recruiting now

Conditions studied: PBMCs

In brief

Peripheral Blood Mononuclear Cells (PBMC) are a mixed population of cells with a single nucleus found in peripheral blood (i.e., blood outside the bone marrow), including natural killer cells (NK), T lymphocytes (70% - 90%), and B lymphocytes. They can be further isolated and purified and are the main source of immune cells. This study will be conducted at our hospital, with a planned recruitment of 200 subjects. Subjects who meet the inclusion criteria and do not meet the exclusion criteria will have their peripheral blood mononuclear cells collected via apheresis. Each subject will need to provide an apheresis sample containing approximately 8×10\^9 mononuclear cells (with a sample volume of about 150 mL).
