23 Jul Cell injection for treating bone injury and preparation method thereof
Abstract
The invention relates to a cell injection for treating bone injury and a preparation method thereof, belonging to the field of tissue engineering. The injection is a compound formed by mesenchymal stem cells from autologous bone marrow, temperature sensitive gel and effective trophic factors separated and extracted from autoblood. The preparation method comprises the steps of: after extracting the bone marrow of a patient, separating and extracting the mesenchymal stem cells from the bone marrow, adding no animal serum in the amplification culture process, and mixing 1*(105-108) cells with 1-5ml of biological scaffold material to form the injectable compound. The cell injection for treating bone injury is mainly used for treating bone injuries including osteoarthritis, femoral head necrosis and delayed union and disunion of bone fracture, is convenient to use, has notable effect without immunological rejection, and can alleviate the great pain of patients caused by bone injury.
