Identification and differentiation of PDX1 β-cell progenitors within the human pancreatic epithelium

Figure 3 Comparison of differentiated (A) and undifferentiated (B) cells from the islet depleted pancreatic tissue infected with PDX1-monomeric red fluorescent protein. A few PDX1⁺ cells (RFP) are visible within the adhered aggregates in the differentiated condition (A). Cell aggregates are absent in the undifferentiated cell conditions (B) and PDX1⁺ cells are within the monolayer. Scale bars are 100 μm. RFP: Red fluorescent protein.
