Scientists identify the neuroblastoma cells that signal poor outcomes

AI Summary

St. Jude Children's Research Hospital researchers and collaborators analyzed a large dataset of neuroblastoma cells to map tumor cell types. They identified a gene signature in a malignant cell population associated with poorer patient outcomes.

Neuroblastoma is the most common solid tumor found outside the brain in children, yet why some children respond well to treatment while others do not has remained poorly understood. St. Jude Children's Research Hospital scientists and their collaborators built one of the most comprehensive datasets of neuroblastoma cells to date, using it to define the tumor's cell types and identify a gene signature marking a malignant cell population tied to poor prognosis.
