In conclusion, our data suggest that overexpression of the Hedgehog components SHH, GLI2 and FOXA2 might be used as markers of an aggressive hemangioma that would benefit from too early intervention, while FGF2 and GLUT1 are more general markers of hemangiomas.
Our lab has identified and isolated hemangioma stem cells (HemSC), glucose transporter 1 positive (GLUT1(+)) endothelial cells (designated as GLUT1(sel) cells) based on anti-GLUT1 magnetic beads selection and GLUT1-negative endothelial cells (named HemEC).
Using immunohistochemistry assay, we examined the expression levels of VEGF, VEGFR2, Ki-67, glucose transporter-1 (Glut-1), phosphorylated protein kinase B (p-AKT) and p-ERK in different phases of human HAs.
