WebbpiRNA has a role in RNA silencing via the formation of an RNA-induced silencing complex (RISC). piRNAs interact with piwi proteins that are part of a family of proteins called the Argonautes. These are active in the testes of mammals and are required for germ-cell and stem-cell development in invertebrates. WebbEmbryo freezing, also called embryo cryopreservation, is a process to freeze and store embryos for later use. An embryo is an egg that has been fertilized by a sperm.
