NicheSphere reveals Spp1⁺ macrophages as central hubs coordinating fibrotic remodeling in myeloproliferative neoplasms
Using a novel computational framework called NicheSphere, this study identifies Spp1⁺ macrophages as central communication hubs that coordinate fibrotic remodeling in myeloproliferative neoplasms by integrating inflammatory and fibrotic signaling with stromal cells, revealing them as promising therapeutic targets for bone marrow fibrosis.
