Tissue preservation is a research area that focuses on preserving and maintaining biological tissues for various purposes, such as medical research, organ transplantation, and biobanking. This field involves developing techniques and methods to prevent tissue degradation, maintain tissue functionality, and ensure long-term storage of tissues. Methods used in tissue preservation may include cryopreservation, chemical fixation, and freeze-drying, among others. Tissue preservation is crucial for advancing medical research, improving organ transplantation success rates, and preserving biological samples for future studies.
