Signaling pathways and bone marrow microenvironment in myelodysplastic neoplasms.

Key signaling pathways within the Bone Marrow Microenvironment (BMM), such as Notch, Phosphoinositide-Specific Phospholipase C (PI-PLCs), Transforming Growth Factor β (TGF-β), and Nuclear Factor Kappa B (NF-κB), play a vital role in the progression of Myelodysplastic Neoplasms (MDS). Among the various BMM cell types, Mesenchymal Stromal Cells (MSCs) are particularly central to these pathways. While these signaling routes can independently affect both MSCs and Hematopoietic Stem Cells (HSCs), they most importantly alter the dynamics of their interactions, leading to abnormal changes in survival, differentiation, and quiescence.
