The main method of preservation of umbilical cord blood is cryopreservation, which is stored in minus 196 liquid nitrogen, and the umbilical cord blood can survive for a long time at -196. The activity of the biological enzyme system of umbilical cord blood hematopoietic stem cells was completely inhibited under liquid nitrogen, but it still had the ability to proliferate and differentiate.
The main functions of cord blood preservation are as follows:
Prevention of primary defects: Umbilical cord blood is rich in hematopoietic stem cells, which can be used for a variety of diseases, including hematologic diseases, malignant tumors, metabolic defects, autoimmune diseases, nervous system damage, etc.
Rebuild human hematopoiesis: Umbilical cord blood can be used for clinical hematologic diseases, malignant tumors, metabolic defects, autoimmune diseases, nervous system damage, etc.
Repair of senescent tissues: Umbilical cord blood contains a variety of growth factors and stem cells, which can promote tissue regeneration and repair, and have a certain effect on aging and damaged tissues.
Prevention and disease: The hematopoietic stem cells in umbilical cord blood can resist environmental pollution such as radiation, drugs, poisons, and germs, and can be accessed at any time. At the same time, hematopoietic stem cells in umbilical cord blood have the advantages of strong proliferation ability and less rejection after transplantation.
It should be noted that although umbilical cord blood is rich in hematopoietic stem cells, not all umbilical cord blood can be used for ** diseases. If you want to preserve cord blood, you need to do it in a professional medical institution and follow the relevant operating practices and regulations.
