[Bone Marrow Microenvironment and Myelodysplastic Syndromes--Review]

Area of Science:

• Hematology
• Bone Marrow Biology
• Malignant Hematology

Background:

• Myelodysplastic syndromes (MDS) are a group of heterogeneous bone marrow failure disorders.
• The bone marrow microenvironment, comprising bone marrow stromal cells (BMSC), growth factors, and cytokines, is crucial for hematopoiesis.
• While BMSCs like mesenchymal stem cells (MSCs), osteoblasts, endothelial cells, and macrophages support blood cell formation, adipocytes are implicated in suppressing it.

Purpose of the Study:

• To review and summarize the abnormalities within the bone marrow microenvironment in the context of myelodysplastic syndromes (MDS).
• To highlight the role of the bone marrow microenvironment in the pathogenesis and progression of MDS.
• To consolidate recent research findings on MDS bone marrow microenvironment alterations.

Main Methods:

• Literature review of recent research on myelodysplastic syndromes (MDS).
• Analysis of the components and functions of the bone marrow microenvironment.
• Synthesis of information regarding the involvement of microenvironmental abnormalities in MDS.

Main Results:

• The bone marrow microenvironment plays a significant role in the development and advancement of MDS.
• Specific cellular components within the microenvironment, such as adipocytes, can negatively impact hematopoiesis in MDS.
• Alterations in the bone marrow microenvironment are increasingly recognized as key factors in MDS pathogenesis.

Conclusions:

• Abnormalities in the bone marrow microenvironment are integral to the pathogenesis and progression of myelodysplastic syndromes (MDS).
• Understanding these microenvironmental changes is critical for developing new therapeutic strategies for MDS.
• Further research into the specific roles of different microenvironmental components, like adipocytes, is warranted.
