More and more families are choosing to store placental stem cells, what is the use of storing neonatal stem cells?
The placenta is the organ of material exchange between the mother and the fetus, and it is also an important hematopoietic and immune tissue. Stem cells extracted from the placenta belong to neonatal stem cells, which have the characteristics of large number, wide application and low immunogenicity. More and more families are opting for placenta to store neonatal stem cells.
What are the neonatal stem cells?
Neonatal stem cells, also known as perinatal stem cells, refer to stem cells derived from the perinatal tissues of newborns. Neonatal stem cells are mainly derived from the placenta and umbilical cord, which are convenient and simple, and will not cause harm to the mother and fetus; Secondly, due to the small degree of contamination, its high purity and strong activity have become the material for many stem cell clinical treatments.
There are four types of neonatal stem cells: placental mesenchymal stem cells, placental hematopoietic stem cells, umbilical cord mesenchymal stem cells, and umbilical cord blood hematopoietic stem cells. Among them, stem cells derived from the placenta have received extensive attention from many experts and scholars in the world, and more and more families choose to store placental stem cells in the Boya stem cell bank.
What is the value of placenta?
The placenta is the place where the mother and the fetus exchange substances, and it is also an important hematopoietic organ, and it is one of the four major immune zones of the human body, which has the effect of regulating immune rejection. People are more familiar with the role of placenta that can be made into traditional Chinese medicine "Zihe car".
However, it should be noted that Zihe car is not suitable for all people, and Zihe car has been removed from the new edition of the Chinese Pharmacopoeia since December 1, 2015. The real medical value of the placenta lies in its abundance of stem cells: placental mesenchymal stem cells and placental hematopoietic stem cells. Both can be used for clinical applications of a variety of difficult and stubborn diseases, opening up a new way for traditional medicine.
I. Placental mesenchymal stem cells
At the 2000 American Hematology Annual Meeting, Jaroscak et al. reported a preliminary study on placenta-derived adherent cells and proved the presence of mesenchymal stem cell components in the placenta, and other studies have also revealed that the placenta is rich in mesenchymal stem cells. Compared with stem cells from other sources, it has a wider range of self-renewal and multilineage differentiation capabilities, and at the same time, it is convenient to obtain placenta from a wide range of sources, usually after the consent of healthy mothers, and has the advantages of low immunogenicity and no ethical issues, so it has attracted extensive attention from scholars.
Placental mesenchymal stem cells can differentiate into a variety of cells in vitro, such as osteoblasts, chondrocytes, and nerve cells. At present, there are many reports of the use of placental mesenchymal stem cells in the treatment of injury, chronic, congenital or immune rejection diseases at home and abroad, and a number of latest clinical randomized controlled trial studies have pointed out that placental mesenchymal stem cells have good effects in the treatment of ischemic myocardial diseases, type II diabetes and other diseases.
II. Placental hematopoietic stem cells
Umbilical cord blood hematopoietic stem cell transplantation is an effective means for the treatment of many hematologic diseases, but the small amount limits the clinical application of umbilical cord blood. The placenta can improve and compensate for this deficiency due to its large amount of hematopoietic stem cells. Moreover, some studies have shown that placental hematopoietic stem cells are more active than hematopoietic stem cells from other sources (such as umbilical cord blood) and survive longer under in vitro culture conditions. In addition to the advantages in content, human placental tissue also has potent immunosuppressive properties. In 2014, the 307 Hospital of the People's Liberation Army used placental hematopoietic stem cells to treat a 9-year-old girl with aplastic anemia.
Newborn stem cells are the gift of life to the baby and to the family. With the development of science, the role of neonatal stem cells will continue to be discovered. The placenta is a good source of neonatal stem cells, how to deal with the placenta and exert its maximum value, the scientific method is to preserve it and extract placental stem cells. It is then stored in the Boya stem cell bank to store the placenta, which is a valuable life resource for the family, and this guarantee is beneficial to the whole family.
