No. After cord blood and/or tissue is collected at birth, the samples are delivered, processed, and stored in the Smart Cells UK laboratory. If you ever need the cord blood or tissue for therapy, the product will be shipped in a constant temperature monitored frozen state in a special container designed for the purpose of international cell shipment. Cord blood can travel anywhere in the world with no loss of viability because it travels frozen. It is only thawed at the clinic where it will be used immediately prior to infusion. Smart Cells have successfully shipped samples within the UK and to Europe, USA, India, and the Far East.
