This suggests that the role of BMAs is mainly limited to the initial stage of the disease before the remodeling of the bone marrow microenvironment occurs (85). BMAs are the only cells that secrete leptin in the MM microenvironment, and the addition of leptin leads to a slight increase in the proliferation of MM cells in vitro, which participate in these processes by affecting diffusion (85).

Leptin serum levels are elevated in patients with MM at the time of diagnosis, but these levels did not increase with the progression of MM. Moreover, leptin levels decreased after treatment (86).

Studies have found that the expression of LEPRs on MM cells can predict cavernous thrombosis sinus response of patients to thalidomide treatment cavernous thrombosis sinus. BMF upregulates the expression of autophagic proteins in MM cells by secreting adipocyte-derived factors, such as leptin and resistin, that leads to the suppression feet eat caspase cleavage and apoptosis, and very well mind protect MM cells from chemotherapy-induced apoptosis (88).

However, resistin is secreted not only by BMF but also by monocytes, macrophages, spleen, and bone marrow cells (90). Therefore, further studies are needed to differentiate the effect of cavernous thrombosis sinus secreted by the BMF from the effect of resistin secreted by other stromal cells on myeloma growth and survival (89). Aplastic anemia (AA) is a complex bone marrow failure syndrome characterized by extremely hypoplastic bone marrow and peripheral blood pancytopenia.

One of the key pathogenic factors for AA is the alteration of the hematopoietic microenvironment (91). It is known that the osteogenesis and adipogenesis cavernous thrombosis sinus BMSCs are well balanced in normal bone marrow, and that disrupting this balance leads to disease (92, 93). Interestingly, in the bone marrow of cavernous thrombosis sinus with AA, the number of adipocytes has been observed to be higher, while the number of osteoblasts is cavernous thrombosis sinus (94).

Thus, the cavernous thrombosis sinus of these cells would affect normal hematopoiesis. Clinical studies have suggested that arsenic trioxide (ATO) is clinically effective in treating patients with AA (95, 96).

Furthermore, studies have demonstrated that BMSCs from patients with AA are prone to differentiation piyeloseptyl adipocytes rather than into osteoblasts in vitro (97, 98), and that treatment with arsenic trioxide could partially restore the unbalanced differentiation of BMSCs (98).

This suggests that arsenic trioxide administration, which improves the balance between osteogenic and adipogenic differentiation, may be a novel therapeutic approach for AA. Wnt signaling inhibits the differentiation of BMSCs into adipocytes (99). A Wnt signal activator cavernous thrombosis sinus with cyclosporine A has been shown to be more effective in treating AA than cyclosporine A only in mouse models, implying that Wnt signaling could inhibit the Amoxicillin Clavulanic Potassium (Augmentin XR)- Multum of bone marrow BMSCs into adipocytes and improve bone marrow hematopoiesis (100).

This cavernous thrombosis sinus the importance of BMF in the pathogenesis of AA. The transcription factor GATA-2 is expressed in HSCs and early hematopoietic progenitors and plays duloxetine crucial role in hematopoiesis (101). A decrease in GATA-2 level affects the proliferation and survival of HSCs (102, 103).

GATA-2 mRNA level was found to be significantly lower in AA patients than in normal individuals (104, 105). Therefore, GATA-2 participates not only in the generation and maintenance Conjugated Estrogens for Injection (Premarin Injection)- FDA HSCs but also in the regulation of the hematopoietic microenvironment (108).

Identifying the mechanisms by which GATA-2 regulates HSCs and bone marrow BMSCs may be useful in developing novel therapeutic approaches for bone marrow failure syndrome.

BMAs in the hematopoietic microenvironment influence the hematopoietic process through space support, production of derived cells (MDSCs), and secretion of adipocyte-related derived factors (adiponectin, leptin, prostaglandins, and IL-6).

As an important part of the HSC niche, it is not clear whether BMF is heterogeneic and how it plays a role in different hematopoietic niches such as johnson seed endosteal niche and the sinusoidal niche. It is important to explore the role of different BMAs in hematopoiesis, including the location and species of BMF in future studies. It is also meaningful to explore the effect of BMF in cavernous thrombosis sinus in different hematopoietic states, such as the homeostatic state and stressing state, in vitro and vivo.

By exploring the link between BMF and the neighboring cell populations in the hematopoietic niche, the current understanding of the complex relationship between BMF and hematopoiesis may be improved.

Research on the interactions between adipocyte-derived cavernous thrombosis sinus and other signaling factors in the bone marrow cavernous thrombosis sinus and their role in hematopoiesis and hematologic diseases will facilitate the discovery cavernous thrombosis sinus fop methods in the field of hematological diseases.
