DLK1 Protein Expression during Mouse Development Provides New Insights into Its Function

Figure 3

DLK1 protein expression in the developing liver. ((A)–(I)) They show sections of ED10, ED12, -13, -14, -15, -16, -17, 18, and D2 livers, respectively, with gradually decreasing DLK1 protein expression. After ED16, an increasing portion of the hepatocytes becomes rapidly negative for DLK1 staining, with completely absent staining on D2. Red blood cells and endothelium (inset in (B)) do not show DLK1 staining at any time point. (e) endothelium and (r) erythrocyte. Scale bar in (A) is applicable for ((B)–(I)).
