Scientists from Novosibirsk were the first in the world to revive mouse embryos frozen during diapause. This was reported by the press service of the Institute of Cytology and Genetics of the SB RAS.
The embryos of some mammals can "freeze" for a while in order to survive. This process is called embryonic diapause. It can last for several weeks or months. And when conditions become better, the embryo begins to develop again.
The result obtained is essential for the use of modern reproductive technologies in the conservation of rare and endangered animal species.
The scientists kept the embryos in a cryostorage. Recently, specialists received the CYTATION 5 - a hardware and software complex that allows continuous monitoring of the development of laboratory animal embryos at early stages. With this device, it is possible to assess the potential viability of embryos and, based on the data obtained, purposefully select them for storage and reproduction.
During experiments in the laboratory of the Institute of Cytology and Genetics of the SB RAS, mouse pups were born. As noted in the institute, this discovery is of great importance for the restoration of populations of rare animal species.
Earlier, Novosibirsk scientists developed an installation for growing artificial blood vessels. It operates on the basis of a collector in the form of a cylinder with teeth of a special shape, onto which conductive threads are wound. For the production of vessels, a polymer is used, which is melted and dosed in an electric field with high voltage. The new method is both simpler and cheaper than others.
