Provided is a composition and an application thereof. The composition is used to prepare a medium for inducing differentiation of human pluripotent stem cells to liver precursor cells. By means of screening active components, optimizing the composition ratio and adding a GSK3-beta inhibitor, a Nodal activator, a BMP activator, a BMP inhibitor and a Hedgehog activator, human pluripotent stem cells are induced to differentiate to liver precursor cells. The process is simple and efficient, the content of positive cells is high, and the cost of cell differentiation is reduced. The invention can be used for research and application in drug development and regenerative medicinal treatment, and has broad application prospects. |
