CGF (Concentrated Growth Factor) is extracted from autologous blood by our specialized variable speed centrifuge DL4-M. The concentration of growth factor is four times higher than that of normal blood active substances and it contains CD34 positive cells and white blood cells with high activity. CD34 positive cells are important Cells for promoting the reconstruction of the micro-circulatory system and collagen regeneration. In the mesoderm, filling and wound repair, micro-capillary and micro-lymphatic systems can be quickly reconstructed in the treatment.
