Changes in gene regulation in bone marrow stem cells of patients with acquired aplastic anemia studied by computer and lab experiments

Aplastic anemia (AA) is characterized by hypocellular bone marrow and a reduction in blood cells.

• Intrinsic abnormalities in bone marrow-derived mesenchymal stem cells (BM-MSCs) may be linked to inadequate support for blood cell formation.
• Cellular aging and chronic inflammation are associated with changes in BM-MSC function in AA.
• Enhanced fat cell formation in the bone marrow could contribute to the disease's progression.
• The epigenetic mechanisms behind BM-MSC abnormalities in AA are not yet fully understood.
• This work aims to clarify the epigenetic factors involved in the failure of the bone marrow niche.
