There are countless firsts in life, and you can start again if you make a mistake. But there is only one thing in one's life. If you miss it, there is no chance. It is "umbilical cord blood"-the first gift brought to mankind by a newborn. It is left in the placenta and umbilical cord after the fetus is delivered, the umbilical cord is ligated and severed. In the blood. More than 30 years ago, it was just medical waste, and it was usually discarded. When a type of hematopoietic stem cell that can be used to treat a variety of diseases is found in the umbilical cord blood, it becomes a valuable resource. The cord blood hematopoietic stem cell bank (stem cell bank for short) used to store cord blood also came into being.

So what exactly does umbilical cord blood do? Self-preservation or donation? How to collect, transport and store? Next, let me answer them one by one.

*Waste utilization, turning waste into treasure”

In the 1970s, a Japanese scholar, Knudtzon, first discovered that umbilical cord blood contains hematopoietic stem cells that can rebuild the human hematopoietic and immune system. In 1988, the world's first umbilical cord blood stem cell transplantation was completed by French doctor Gluckman and others. They used the hematopoietic stem cells in the umbilical cord blood to successfully treat a five-year-old child with Fanconi's anemia. Umbilical cord blood contains a large number of stem cells. Stem cells are the seeds of life. They differentiate into various cells of the human body and produce various fruits-blood cells, nerve cells, bone cells and so on. Stem cells are cell populations with self-renewal, high proliferation and multiple differentiation potentials. They also play an active role in tissue repair and other aspects.

Up to now, there have been more than 45,000 clinical application cases of cord blood hematopoietic stem cell transplantation worldwide. Umbilical cord blood has also been proven to be used to treat various types of leukemia, aplastic anemia, lymphoma, multiple myeloma, neuroblastoma, mucopolysaccharidosis, thalassemia, myelodysplastic syndrome, primary immunodeficiency, More than 80 diseases such as chronic granulomatosis.

Hematopoietic stem cells (HSC) are currently the only stem cells approved for clinical use in my country, which can rebuild the blood system and immune system. The "Technical Management Specifications for Hematopoietic Stem Cell Transplantation (2017 Edition)" promulgated by the Health Commission in February 2017 stipulates that hematopoietic stem cells that can be used in clinical applications can only be derived from bone marrow, peripheral blood and cord blood.

*Self-preservation is a guarantee, donations for love”

For parents-to-be, self-preservation and donation are both voluntary choices. The cost of self-storage cord blood ranges from US$ 20,000 to US$50,000. The general storage period is 18-20 years, and the child can choose to renew or stop the storage when he grows up. Self-existing stem cells have an advantage in matching types due to  their small rejection in the body . Their storage volume is much larger than the donated public stock. However, as the application technology of stem cells improves and the prospects become wider and wider, we encourage parents of newborns to donate cord blood. The larger the storage of the public library, the more people who need it will be assured and guaranteed.

*How are umbilical cord blood and tissues collected, transported and stored safely? Since umbilical cord blood has so many uses, its collection, transportation and storage have become crucial. After all, there is only one chance in a lifetime. The storage of umbilical cord blood requires collection, transportation, stem cell separation, preparation, program-controlled cooling, and stem cell and pathogen detection. Only after it is qualified can it be frozen in a deep cryogenic liquid nitrogen tank at -196°C for a long time.

So how to solve the problem of umbilical cord blood from collection to fast and safe transportation to the stem cell bank has always been a big problem for expectant parents and stem cell banks. the advent of the "source of life" cord blood tissue collection box has solved this problem. This is another masterpiece that International Haotian Technology has spent 2 years of hard work to develop. Let us have a deeper understanding of how the "source of life" works.
