This article has been corrected: The authors found that the image of the control endothelial progenitor cells (EPCs) in the tube formation assay shown in Figure 3A was incorrect due to their unintentional reuse of the image of cells treated with the PI3K inhibitor Y294002. They replaced the incorrect image with an image of control cells from the same experiment. This correction has no impact on the experimental outcome or conclusions.
The corrected Figure 3 is shown below.

Figure 3. SHH pathway induces angiogenesis properties of EPCs by PI3K/AKT/eNOS signaling. (A, B) The EPCs were treated with SAG (1 μM), cyclopamine (10 μM), Y294002 (5 μM), or co-treated with SAG (1 μM) and Y294002 (5 μM). The angiogenesis properties were analyzed by tube formation assays. N = 3.
