Immune system and bone marrow stromal cells play an important role in maintaining normal hematopoiesis. Lymphoid neoplasia disturbs not only development of immune cells, but other immune response mechanisms as well. Multipotent mesenchymal stromal cells (MSCs) of the bone marrow are involved in immune response regulation through both intercellular interactions and secretion of various cytokines.

In patients with acute leukemia, not only normal hematopoiesis, but also bone marrow stromal microenvironment is damaged. Multipotent mesenchymal stromal cells (MSC) are essential for the formation and function of the stromal microenvironment. Analysis of changes in MSC is important for the development of new approaches to leukemia therapy.

In patients with acute myeloid leukemia (AML), malignant cells modify the properties of multipotent mesenchymal stromal cells (MSCs), reducing their ability to maintain normal hematopoiesis. The aim of this work was to elucidate the role of MSCs in supporting leukemia cells and the restoration of normal hematopoiesis by analyzing ex vivo MSC secretomes at the onset of AML and in remission. The study included MSCs obtained from the bone marrow of 13 AML patients and 21 healthy donors.

In acute leukemia, the stromal microenvironment of the bone marrow that regulates hematopoiesis is modified under the influence of malignant cells. Chemotherapy also adversely affects stromal cells. Multipotent mesenchymal stromal cells (MSC) are involved in the formation of the stromal microenvironment and in the regulation of normal and tumor hematopoietic cells.

Multipotent mesenchymal stromal cells (MSCs) are an object of intense investigation due to their therapeutic potential. MSCs have been well studied in vitro, while their fate after implantation in vivo has been poorly analyzed. We studied the properties of MSCs from the bone marrow (BM-MSC) before and after implantation under the renal capsule using a mini pig model.
