How Does the Process Work?

Your baby’s umbilical cord blood is collected after delivery, and the cord has been clamped and cut. The collection procedure includes rigorous decontamination of the cord prior to collection of the cord blood. The blood is then collected in a closed system, which is the superior method for minimizing contamination.

Cord blood can be obtained before or after the delivery of the placenta (afterbirth). In the post placental method (ex-utero method), the trained personnel collects the umbilical cord blood after the afterbirth has been taken out of the mother’s womb. In the preplacental method (in-utero method), the physician/obstetrician collects the cord blood in the delivery unit while the placenta is still in the womb.

Using sterile techniques, your doctor, midwife or labor & delivery nurse will insert a sterile needle into the umbilical vein to allow drainage of the blood by gravity into a sterile bag containing anticoagulant.

StemCyte Family provides detailed instructions for your healthcare provider. Also, our medical staff is available 24 hours a day, 7 days a week to answer questions from healthcare providers and labor & delivery staff.

Collection can be accomplished either through a closed system via a sterile bag or an open system using a syringe. The StemCyte International Cord Blood Center strongly recommends and only provides blood bags for collection. It is a closed system that minimizes the risk of bacterial and fungal contamination, and it is preferred by transplant physicians for its safety.

The entire collection process averages five to ten minutes and does not interfere with the first minutes of bonding between baby and parents.

The collected unit is transported to the StemCyte International Cord Blood Center for further processing, testing and storage.

All necessary materials for collecting and shipping the cord blood are contained in the collection kit sent to you. The hospital will not need to provide any materials.

Transport To Our Center

StemCyte Family is unique among family banks in that we use heavily insulated transport containers validated to maintain an optimum temperature during shipment under all weather conditions throughout the United States.

Simply call us, and we'll take care of all of the logistics. We arrange getting the transport container from the hospital to our processing laboratory.

Your baby's cord blood bag is sealed and placed in the transport box along with the necessary paperwork. It is transported by highly experienced couriers to StemCyte’s processing laboratory in Arcadia, CA. Cord blood that has been collected must be processed within 48 hours in order to store the highest quality product for transplantation.

When it arrives, your baby’s cord blood unit is processed and undergoes testing, including infectious disease testing, total cell count, and sterility. Thereafter, the cord blood unit deemed acceptable for transplantation is stored in liquid nitrogen until needed.

Processing

The processing of your baby’s umbilical cord blood will take place in the state-of-the-art laboratory at the StemCyte International Cord Blood Center. StemCyte’s proprietary processing methods will result in the highest possible yield of stem cells with excellent cell life. Only the plasma is removed from the cord blood unit. Other cord blood banks first remove the red cells, which may decrease the yield of stem cells.

Our highly trained staff will process your baby’s cord blood in accordance with over 400 validated procedures. Our proprietary method results in the highest possible yield (over 90% recovery) of stem cells. This is critical to providing a product of unsurpassed quality that will maximize the opportunity for a successful transplant of the cord blood unit should your baby or a family member ever need it.

Each collected cord blood unit undergoes several tests to ensure safety, sufficient cell count, and viability of the stem cells. These include: infectious disease testing for certain diseases such as the AIDS virus (HIV), hepatitis, syphilis, cytomegalovirus and HTLV I/II virus; blood typing (ABO and Rh typing); fungal and bacterial cultures; total nucleated cell count; viability assay and CD34 testing. On occasion, genetic tests may also be performed when deemed necessary, for example, if there is a family history of inherited diseases. Additionally, the mother’s peripheral blood is also tested for infectious disease as described above.

Storage

Unless or until your baby’s cord blood is needed for a transplant, it will be stored at very low temperatures in storage freezers containing liquid nitrogen. The exact expiration date of the unit is unknown because the field of umbilical cord blood transplantation is still relatively new. However, some studies have revealed that cryopreserved cord blood cells, stored more than 15 years, have remained viable. Many transplant experts believe cord blood stem cells may remain viable indefinitely.

StemCyte’s quality program and method for assuring the identity of the cord blood ensures that your baby’s cord blood will be accurately identified. Cord blood units are bar code labeled and repeatedly checked for proper identification. The frozen cord blood is stored in locked, stainless steel liquid nitrogen freezers in our state-of-the-art facility. The temperature of the storage freezers is monitored continuously and any deviation from the proper temperature is immediately brought to the attention of laboratory staff. The freezers have double locks and require two individuals for accessing the cord blood units.
