Tissue banks are facilities that collect, process, store, and distribute human tissues for medical research and transplantation. These tissues can include skin, bone, corneas, and organs, which are vital for treating various medical conditions. Tissue banks ensure that the donated materials are safe and suitable for use, following strict guidelines and regulations. The tissues are typically obtained from donors who have consented to donate after death or from living donors. Researchers and healthcare providers use these tissues to study diseases, develop new treatments, and perform surgeries. This process helps improve patient outcomes and advance medical science.
