Stem cell collection also need to insert catheter

Stem cell collection usually

involves extracting stem cells from bone marrow, peripheral blood or umbilical cord blood. Bone marrow collection is performed by local anesthesia at a specific site of the ilium, and then a bone marrow sample is drawn using a special needle without inserting a catheter. Peripheral blood stem cell collection is automatically performed by a blood cell separation instrument, usually by puncturing a vein site at both elbows to allow blood to flow out of the body without inserting a catheter. Umbilical cord blood stem cells are collected from newborn umbilical cord blood by blood cell separator, which also does not require urinary catheter insertion.
