Background
In the collection of placenta, amnion and umbilical cord and the extraction and preservation of stem cells, the qualification of the collection and the inspection of placenta samples directly influences the tissue and cell culture results and the activity of stem cells. The placenta is stripped from the uterus, contains a large amount of blood, is mixed with meconium, mother manure and amniotic fluid, and is very easy to be infected with bacteria. The washing and disinfection can be carried out in time, so that the further breeding of bacteria and fungi can be avoided. And the cryopreservation is beneficial to the activity maintenance of tissue cells. However, in actual work, the placenta is difficult to be washed in an operating room in an open manner, and the condition that the placenta is given in a low temperature environment of 4 ℃ in time cannot be guaranteed, so that the quality of stem cells obtained from the placenta and tissues is greatly influenced to a certain extent.
The most widely used tissue cell preserving fluid is that penicillin, streptomycin and amphotericin B are added to prevent fungi and bacteria from breeding, but the antibiotics have great influence on the activity of the tissue cells and are not beneficial to later cell culture. The antibacterial peptide can resist fungi and bacteria, has small activity to tissue cells, is firstly found to be bombesin (Magainins) separated from skin of amphibian frogs, and not only acts on G & lt + & gt and G & lt- & gt, but also has killing effect to fungi and protozoa. Lactein (Nisin) is a polypeptide substance consisting of 34 amino acids and produced by lactococcus lactis, can inhibit the growth of most gram-positive G + bacteria, including bacillus (such as clostridium botulinum), heat-resistant putrefying bacteria (such as bacillus stearothermophilus), clostridium sporogenes and the like, but has no effect on yeast and mold, and has heat stability under acidic conditions.
