Insights

Angiogenesis is crucial in multiple myeloma (MM) progression. Bone marrow stromal cells, macrophages, mast cells, and hematopoietic stem and progenitor cells (HSPCs) all contribute to tumor growth and blood vessel formation in MM.

Area of Science:

  • Oncology and Hematology
  • Tumor Microenvironment Research
  • Angiogenesis Studies

Background:

  • Angiogenesis is a key driver in both solid and hematologic malignancies.
  • Multiple myeloma (MM) progression involves complex interactions within the bone marrow microenvironment.
  • Bone marrow stromal cells are critical for supporting myeloma cell survival and angiogenesis.

Purpose of the Study:

  • To elucidate the multifaceted roles of various cell types in angiogenesis within multiple myeloma.
  • To understand the contribution of bone marrow stromal cells, macrophages, mast cells, and HSPCs to tumor vascularization in MM.

Main Methods:

  • Review and synthesis of existing literature on angiogenesis in multiple myeloma.
  • Analysis of the mechanisms by which different cell types contribute to tumor vascularization.

Main Results:

  • Bone marrow stromal cells release angiogenic cytokines, promoting tumor survival and vascularization.
  • Macrophages and mast cells contribute to angiogenesis through mechanisms like vasculogenic mimicry.
  • Hematopoietic stem and progenitor cells (HSPCs) are implicated in vasculogenesis in the context of MM.

Conclusions:

  • Multiple cell types within the bone marrow microenvironment actively participate in angiogenesis in multiple myeloma.
  • Targeting these cellular contributions could offer novel therapeutic strategies for MM.
  • Understanding these complex cellular interactions is vital for advancing MM treatment.

Regulation of Angiogenesis and Blood Supply01:24

Regulation of Angiogenesis and Blood Supply

Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits.  Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl hydroxylase and factor...
Mechanism of Angiogenesis01:10

Mechanism of Angiogenesis

Blood vessel formation starts early during embryonic development, around day 7. In the extraembryonic yolk sac, mesodermal precursor cells called hemangioblast proliferate and differentiate into angioblast. Angioblasts express vascular endothelial growth factor receptor 2 or VEGFR2, which binds VEGF-A, a proangiogenic factor, guiding blood vessel formation. VEGF signaling promotes angioblasts to form a blood island in the developing embryo. Angioblasts further differentiate, giving rise to...

Inflammatory Response I: Vascular and Cellular

The inflammatory response is the body's defense against infection, injury, or irritation from bacteria, trauma, toxins, or heat. Inflammation helps locate and destroy pathogens and remove damaged tissue elements to heal the body. During this initial phase, fluid, blood products, and nutrients migrate to the injured area, resulting in redness, heat, swelling, ache, and loss of function. Moreover, signs of systemic inflammation include fever, increased WBC count, malaise, anorexia, nausea,...

Differentiation of Common Myeloid Progenitor Cells

Common myeloid progenitors (CMPs) are oligopotent cells that can differentiate into granulocytes and macrophages. Granulocytes and macrophages are essential for protecting the body against bacterial, viral, or fungal infections. They migrate from the bone marrow into the circulating blood to reach specific tissue sites where they differentiate and help in immune surveillance. However, they survive only for a few days and must be continuously made available to the organism to maintain a robust...
The Tumor Microenvironment02:17

The Tumor Microenvironment

Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...
