- (a) introducing blood or BMA into a first body of a first syringe having a first diameter;
- wherein the first syringe is in direct fluid communication with
- (i) a second syringe having a second body with a second diameter;
- and
- (ii) a third syringe, having a third body with a third diameter;
- wherein the first, second, and third syringes can be removed from each other;
- (b) subjecting the first, second, and third syringes to centrifugation to obtain two or more of blood or bone marrow fractions including at least a first fraction and a second fraction within the first body of the first syringe;
