We carefully select the culture medium required for cultivating stem cells, and XOSOME Biosciences does not use any culture medium containing animal derived ingredients as the nutrient solution for stem cells. This reduces the risk of infectious diseases that may originate from animals to zero, abbreviated asAOF(Animal Origin Free). Meanwhile, the growth factors and anti-inflammatory molecules we cultivate possess extremely high value-added properties and excellent safety with the support of extensive clinical practice. Despite its high cost, it can maintain a leading advantage in both quality and quantity in the market.
