Granulomas in bone marrow are an infrequent finding and several diseases are associated with granuloma formation. Clinicopathological details of fourteen cases showing granulomas in bone marrow were studied. Fever was the commonest clinical presentation and anaemia was seen in all cases. Only one case showed epithelioid cells in the bone marrow aspirate smear while trephine biopsy was diagnostic in all cases. Granulomas were seen mainly in the paratrabecular space. Acid fast bacilli were demonstrated in five biopsies and serological test for Human Immunodeficiency virus was positive in five cases. Tuberculosis was more common in the present study as compared to others, probably due to the endemicity of tuberculosis in this region. Bone marrow biopsy is useful in the investigation of pyrexia of unknown origin as it leads to an aetiological diagnosis in most cases.

The biology centered around the TGF-beta type I receptor Activin Receptor-Like Kinase (ALK)1 (encoded by ACVRL1) has been almost exclusively based on its reported endothelial expression pattern since its first functional characterization more than two decades ago. Here, in efforts to better define the therapeutic context in which to use ALK1 inhibitors, we uncover a population of tumor-associated macrophages (TAMs) that, by virtue of their unanticipated Acvrl1 expression, are effector targets for adjuvant anti-angiogenic immunotherapy in mouse models of metastatic breast cancer. The combinatorial benefit depended on ALK1-mediated modulation of the differentiation potential of bone marrow-derived granulocyte-macrophage progenitors, the release of CD14+ monocytes into circulation, and their eventual extravasation.

B-cell acute lymphoblastic leukemia (B-ALL) is the most common form of cancer diagnosed in children. While the majority of patients survive with conventional treatment, chemotherapeutic agents have adverse effects and the potential for relapse persists even after full recovery. Given their pivotal function in anti-cancer immunity, there has been a surge in research exploring the potential of natural killer (NK) cells in immunotherapy, which has emerged as a promising avenue for treating leukemia.

Purpose: Despite advances in the treatment of adult acute lymphoblastic leukemia (ALL), relapse remains the most significant challenge in improving prognosis. Measurable residual disease (MRD) assessment can predict bone marrow relapse based on MRD positivity. As access to innovative therapies remains limited because of the high cost, chemotherapy is the widely utilized treatment option.

Leukemia covers a broad category of cancer malignancies that specifically affect bone marrow and blood cells. While different kinds of leukemia have been identified, effective treatments are still lacking for most forms, and even those treatments considered effective can lead to relapses. MicroRNAs, or miRNAs, are short endogenous non-coding single-stranded RNAs that help control the epigenetics of gene expression.

Adult tissue stem cells of the anterior pituitary gland, CD9/SOX2-positive cells, are believed to exist in the marginal cell layer (MCL) bordering the residual lumen of the Rathke's pouch. These cells migrate from the intermediate lobe side of the MCL (IL-MCL) to the anterior lobe side of the MCL and may be involved in supplying hormone-producing cells. Previous studies reported that some SOX2-positive cells of the anterior lobe differentiate into skeletal muscle cells.
