Human Primary Umbilical Cord Mesenchymal Stem Cells

Cell Details

The umbilical cord is a mammalian tubular structure that connects the fetus to the placenta. The umbilical cord that passes through the urinary tract is the umbilical artery and the umbilical vein, and the blood vessels of the yolk sac are the umbilical mesenteric artery and the umbilical mesenteric vein. In the uterus, the capillaries of the uterine artery in the mother part of the placenta are close to the fetal capillaries of the part of the placenta, where CO2 and O2 are carried out between the mother and the fetus, and the metabolites are metabolic wastes and nutrients. exchange. The umbilical artery transports the waste from the fetus to the placenta, which transports O2 and nutrients from the placenta to the fetus. Umbilical cord mesenchymal stem cells (MSCs) are pluripotent stem cells that are present in the umbilical cord tissue of newborns. They can differentiate into many kinds of tissue cells, and have the advantages of convenient materials and no ethical controversy.Cell Characteristics

1) Cells are derived from human umbilical cord tissue. 2) Cell identification: CD105 immunofluorescence staining was positive. 3) The purity of the identified cells is higher than 90%. 4) Does not contain HIV-1, HBV, HCV, mycoplasma, bacteria, yeast and fungi. 5) Cell growth mode: spindle cells, irregular cells, adherent culture.Transportation and Preservation

Depending on the weather conditions and the distance of transportation, the company negotiates with the customer and chooses one of the following methods.1) 1mL of frozen cell suspension is placed in a 1.8mL cryotube and placed in a foam incubator filled with dry ice for transport; after receiving the cells, thaw the resuscitated cells as soon as possible for culture. If resuscitation is not possible immediately, Cryopreserved cells can be stored at -80°C for 1 month.2) T-25 culture flask is filled with complete medium and then transported at room temperature. After receiving the cells, please observe the growth state of the cells under a microscope. If the bottle filling rate exceeds 85%, please carry out the subculture immediately. If there are more cells in suspension, allow the flask to stand overnight in the incubator to help the undead suspension cells to reattach.Product Use
