Criação de bancos biológicos criopreservados para conservação de mamíferos

Yann, Locatelli

Preservation of endangered species represents a challenging perspective regarding quick decline of biodiversity. With benefit of human medicine and agronomic research developments, a wide range of reproductive biotechnologies are now available to facilitate conservation of mammals threatened with extinction. Cryopreservation of gametes, embryos and gonadal tissues are important to be performed for many endangered species on the basis of use of standardized methodologies. Examples of interspecific gestations have been reported for several mammalian species, indicating that some species can be restored using frozen embryos transfer even after extinction. This short review focuses on different illustrations of gametes and tissues cryopreservation among different mammalian species for creation of biological resource banks.
