Keratin-8 human is widely used in biomedical research to study epithelial cell biology and its role in maintaining cellular structure and integrity. It serves as a key marker for identifying and characterizing epithelial tissues, particularly in the context of cancer research, where its expression patterns can help differentiate between tumor types. Additionally, it is employed in the development of diagnostic tools for diseases such as liver disorders, where its presence or absence can indicate tissue damage. In tissue engineering, Keratin-8 human is utilized to create biomimetic scaffolds that promote epithelial cell growth and regeneration. Its role in studying cellular stress responses and apoptosis also makes it valuable in understanding disease mechanisms and developing therapeutic strategies.
