Recombinant fibronectin fragment for efficient stem cell proliferation
A recently granted patent (Publication Number: US11999972B2) discloses a novel recombinant polypeptide designed to maintain the undifferentiated state of stem cells. The polypeptide comprises specific repeats of human fibronectin III sequences, with variants allowed as long as they maintain at least 90% identity to the original sequences. The molecular weight of the recombinant polypeptide is limited to 100 kDa or less, ensuring its effectiveness in stem cell maintenance. Additionally, the patent includes claims for variations of the polypeptide, such as different combinations of fibronectin III repeats, expanding the potential applications of this innovative molecule.
Furthermore, the patent covers the use of the recombinant polypeptide in various solid phases, including devices for cell culture and carriers coated with the polypeptide. These solid phases can range from dishes and plates to beads and membranes, providing a versatile platform for stem cell research and applications. By specifying the types of solid phases that can be coated with the recombinant polypeptide, the patent aims to facilitate the integration of this novel molecule into existing cell culture technologies, potentially advancing the field of regenerative medicine and biotechnology.
