Collection and Storage
While cord blood is collected by a health care provider at the hospital, the placenta must be sent back to the laboratory for processing before the stem cells can be recovered. As such, placental stem cell collection and processing is more intensive than cord blood stem cell processing.
Both placental and cord blood stem cell units are processed and depleted of red blood cells and then cryopreserved in liquid nitrogen tanks at -196 degrees Celsius. Placental and cord blood stem cells units are stored in two separate cryopreservation bags, yielding two separate stem cell units. Recently, it has become evident that to preserve the greatest number of stem cells from the cord blood and placenta, cryopreserving the entire placenta in combination with cord blood banking is generally the best option since by cryopreserving the entire placenta, one may preserve up to 10 times more stem cells than other methods.

Famous quotes containing the words collection and/or storage:
“The Nature of Familiar Letters, written, as it were, to the Moment, while the Heart is agitated by Hopes and Fears, on Events undecided, must plead an Excuse for the Bulk of a Collection of this Kind. Mere Facts and Characters might be comprised in a much smaller Compass: But, would they be equally interesting?”
—Samuel Richardson (1689–1761)
“Many of our houses, both public and private, with their almost innumerable apartments, their huge halls and their cellars for the storage of wines and other munitions of peace, appear to me extravagantly large for their inhabitants. They are so vast and magnificent that the latter seem to be only vermin which infest them.”
—Henry David Thoreau (1817–1862)
