Stem Cell–Associated Proteins Can Identify Origins of Pediatric Tumors

Research has indicated that certain sarcomas come from the mesenchymal stem cells. However, expression of neural stem cells has been noted in others. Identifying and isolating mesenchymal stem cells and neural stem cells relies on finding specific proteins expressed by both types.

In this study, eight different markers representing proteins associated with these two types of stem cells were applied to the 81 tumors. Through cluster analysis, the researchers organized the data into groups showing similar patterns. Two major subgroups of pediatric sarcomas emerged
