Many internal human specimens acquired by medical schools and academic hospitals are sourced from the surgical pathology service at their sites. These acquisitions are usually made from tissue scraps from surgical resections. Since surgical pathology is primarily concerned with patient care, there are many competing tissue needs. It is important to ensure adequate tissue preservation for clinical diagnosis.
It is important to have trained pathology staff involved in the process of human tissue procurement at https://www.geneticistinc.com/blog/why-human-tissue-procurement-is-so-important. These guidelines are a reflection of good surgical pathology practice, including the pathologic characteristics of different anatomic sites, and the typical goals of research biorepositories.

The development of modern medicine depends on the use of human tissue. Failed drug development is costing pharmaceutical companies millions of dollars every year. Human tissue is preferred over animal samples in research because it is safer and faster for patients during clinical trials. This saves money, and drug companies will pay a premium for different types of cells, tissues, and organs in order to speed up their research.
The majority of human tissue used for research in the United States comes from deceased donors. They are only available from hospitals, organ procurement organizations, tissue banks, and other regulated, sterile medical facilities. While there is an endless supply of private and public research companies, the demand is infinite. However, it is limited and finite by nature.
Over the past decade, biomedical entrepreneurs have emerged with private companies whose founders insist on ethical and legal compliance. Geneticist is proud to contribute to this growing community and participate in the global effort to create a more sustainable world.
