OLIG2 and spindle cell hemangioma: No significant differences were found in the densities of NeuN(+) and NeuN(−)/olig2(−) nuclei in the FPCs of either group, nor in those containing total (7-AAD(+)), NeuN(+), olig2(+) and NeuN(−)/olig2(−) nuclei in the ITC of control versus BPD or SCH patients (Figure 1b,d,e-h).
