Maternal Blood Plasma

cord blood plasma

Human maternal blood plasma contains a variety of cytokines, chemokines, and growth factors that allow an effective means of monitoring the health of the fetus and mother. Additionally, cell-free DNA from the fetus is present in maternal plasma and can be used to develop screens and diagnostic tests to determine genetic abnormalities.

Maternal blood is collected from pregnant volunteers participating in Institutional Review Board (IRB) approved donor programs at one of our Stem Cell Collection Centers. All collections follow a standardized collection procedure to guarantee consistency from donor to donor, eliminating variability in the collection procedure. After collection, fresh maternal blood is sent to our FDA-registered cell manufacturing facility where the blood is spun down in order to separate out the plasma fraction.
