Amphibians are ectothermic, tetrapod vertebrates of the class Amphibia. Modern amphibians are all Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in recent decades there has been a dramatic decline in amphibian populations for many species around the globe.
Construction method and application of ovary cell line of vijaynathella emeiensis
ActiveCN121759395BMicrobiological testing/measurementMicroorganism based processesAnimal scienceGermplasm
The application discloses a construction method and application of an ovary cell line of Quasipaa spinosa. The method comprises the following steps: selecting metamorphosis period larva ovary tissue, disinfecting and obtaining the ovary tissue, and then using collagenase I digestion solution to digest the ovary tissue at 26 DEG C for 1 hour; after the tissue block adheres to the wall, using a low-osmotic-pressure complete culture medium to carry out primary culture at 25-27 DEG C, wherein the culture medium is 60% diluted DMEM / F12 culture medium containing 10%-15% fetal bovine serum; when the cell confluence degree is higher than 70%, using trypsin-EDTA to digest the cells for 1-2 minutes to subculture, and the subculture culture medium contains 30% cell conditional culture medium; and finally, the cells are cryopreserved through programmed cooling. The ovary epithelial cell line of Quasipaa spinosa is successfully established for the first time, the survival rate of the cells after recovery is high, and the karyotype is stable. The constructed cell line can be used for amphibian reproductive biology research, compound screening and in-vitro conservation of germplasm resources.
