A recently granted patent (Publication Number: US11918609B2) discloses a method for promoting cutaneous burn healing in a subject by administering specific cells in an effective amount and for a sufficient duration. These cells, referred to as cells (I), are non-embryonic non-germ cells expressing CD90 and either oct4 or telomerase, without being transformed, tumorigenic, or having an abnormal karyotype. The method involves the administration of these cells directly, not from a functionalized substrate, to facilitate the healing process.

Furthermore, the patent claims specify various aspects of the method, including the differentiation potential of the cells into different embryonic lineages, the source of the cells (such as bone marrow or human-derived), the mode of administration (topical, subcutaneous, or injection), and the use of liquid cell suspension or reservoir for delivery. The method also highlights the allogeneic nature of the cells, emphasizing their compatibility for use in human subjects. Overall, the patent provides a detailed framework for utilizing these specific cells to promote cutaneous burn healing effectively.
