Recombinant Human Keratinocyte Growth Factor (OsrhKGF) is widely used in medical and biotechnological applications due to its ability to stimulate the growth and repair of epithelial cells. It plays a crucial role in treating conditions involving epithelial tissue damage, such as mucositis caused by chemotherapy or radiation therapy in cancer patients. By promoting the regeneration of mucosal lining in the mouth, throat, and gastrointestinal tract, it helps alleviate pain and improves recovery. Additionally, OsrhKGF is utilized in wound healing research, particularly for skin injuries and burns, as it accelerates tissue repair and reduces scarring. Its production in Oryza sativa (rice) ensures a cost-effective and scalable method for generating high-quality, biologically active protein for therapeutic purposes.
