Fig. 2From: Stepwise differentiation of functional pancreatic β cells from human pluripotent stem cellsImprovements to efficient differentiation of human PSC-derived pancreatic β cells. The current improvements of efficient differentiation mainly focus on exploring signal pathways. Key signal pathways and related molecules are shown in the graph. The top half of the figure depicts the commonly manipulated signaling pathways; the bottom half shows the recently reported signaling pathways or molecules improving differentiation efficiencyBack to article page
