Single-Cell and Spatial Transcriptomics Study of Meningeal Solitary Fibrous Tumors Academic Background Meningeal Solitary Fibrous Tumors (SFTs) are rare mesenchymal tumors originating from the meninges of the central nervous system (CNS). Although SFTs are histologically similar to other meningeal tumors (such as meningiomas), their unique clinical...
