The bone marrow stroma in hematological neoplasms—a guilty bystander

The Role of Bone Marrow Aspiration and Bone Marrow Biopsy in Diagnosis of Bone Marrow Metastases

Background: Bone marrow is the site of many malignant disorders and it is one of the common places for solid tumors to metastasize. Examination of the bone marrow aspirate and biopsy is a routine procedure performed for assessment of various conditions such as cytopenias, hematologic neoplasms, nonmalignant disorders and metastatic neoplasms. Methods: The patients were referred to the Hema...

Bone Marrow Stroma Confers Resistance to

Expression of proteoglycan core proteins in human bone marrow stroma.

Heparan sulphate proteoglycans (HSPGs) present on the surface of bone marrow stromal cells and in the extracellular matrix (ECM) have important roles in the control of adhesion and growth of haemopoietic stem and progenitor cells. The two main groups of proteoglycans which contain heparan sulphate chains are members of the syndecan and glypican families. In this study we have identified the mai...

Diagnostic Utility of Bone Marrow Sampling and Profile of Hematological Abnormalities in Indian HIV-infected Individuals

Background: Hematological abnormalities are a common complication of HIV infection and occur in all stages of the infection. These abnormalities increase as the disease advances. We aimed to evaluate the diagnostic utility of bone marrow sampling in HIV-positive patients. Methods: 40 HIV-infected individuals were screened for hematological abnormalities. Investigations such as iron studies, he...

MRI of bone marrow abnormalities in hematological malignancies.

Magnetic resonance imaging (MRI) is essential for evaluating bone marrow. Bone marrow undergoes constant modification and its appearance on MRI changes in response. Knowledge of the types of changes and their origins is essential for analysis of MRI findings of bone marrow infiltration with hematological malignancies. This pictorial review describes the MRI pulse sequences used for imaging of b...
