Understanding FFPE Tissue Samples: Preserving the Past, Shaping the Future of Medical Science
In the quiet corners of laboratories and pathology departments around the world, a powerful story is silently unfolding—one that begins with a biopsy and stretches into decades of discovery. It’s the story of FFPE tissue samples—formalin-fixed, paraffin-embedded specimens—that have become the silent custodians of our cellular history. Though they sit tucked away in slides and blocks, these samples are vital to modern diagnostics, personalized medicine, and groundbreaking research.
What Are FFPE Tissue Samples?
To the untrained eye, FFPE might sound like another acronym in the sea of medical jargon. But for researchers, pathologists, and oncologists, FFPE samples are invaluable tools. The process starts when a tissue sample, such as a tumor biopsy, is preserved by fixing it in formalin to halt cellular decay. This tissue is then embedded in paraffin wax, stabilizing it for long-term storage.
This method,…
