Our previous studies showed that the angiogenic integrin αvβ3 was increased in high-risk metastatic (stage 4) NB compared with localized neuroblastomas. Herein, we show that integrin αvβ3 was expressed on 68% of microvessels in MYCN-amplified stage 3 neuroblastomas, but only on 34% (means) in MYCN-non-amplified tumors (p YR 2016 FD 2016-11-18 LK https://hdl.handle.net/10668/25125 UL https://hdl.handle.net/10668/25125 LA en DS RISalud RD Apr 4, 2025
