SLC2A1 and capillary hemangioma: This is based on the finding that the expression pattern of cellular markers (e.g, GLUT-1, merosin, FcRII, Lewis Y antigen, type 3 iodothyronine deiodinase, indoleamine 2,3-deoxygenase, and IGF2) and transcriptomes in infantile hemangioma tissue differ from that of ECs in the surrounding skin, but resemble those of ECs lining fetal microvessels in the human placenta [23].
