Insights

Mononuclear cells (MNC) from psoriasis patients significantly reduced bone marrow colony formation in healthy volunteers, suggesting a potential role in psoriasis pathogenesis. Further research is needed to understand these hematopoiesis abnormalities.

Area of Science:

  • Hematology
  • Immunology
  • Dermatology

Context:

  • Psoriasis is a chronic inflammatory skin condition with potential systemic manifestations.
  • Hematopoiesis, the formation of blood cellular components, can be affected by inflammatory diseases.
  • Colony-stimulating factors (CSFs) are crucial for regulating blood cell production.

Purpose:

  • To investigate the effect of mononuclear cells (MNCs) from psoriasis patients on bone marrow colony formation.
  • To assess potential abnormalities in hematopoiesis induced by psoriasis-derived MNCs.

Summary:

  • Culturing bone marrow cells with MNCs from patients with psoriasis vulgaris and psoriasis arthropathica resulted in significantly reduced colony formation compared to controls.
  • Psoriasis vulgaris group showed 65 +/- 14 colonies (p < 0.001) and psoriasis arthropathica group showed 63 +/- 11 colonies (p < 0.001), versus 116 +/- 23 in healthy controls.
  • These findings indicate an inhibitory effect of psoriasis MNCs on hematopoietic progenitor cells, detected via colony-forming assays.

Impact:

  • The study highlights a potential link between psoriasis and aberrant hematopoiesis, suggesting a novel mechanism in disease pathogenesis.
  • Understanding these hematopoiesis abnormalities could lead to new therapeutic targets for psoriasis and related conditions.
  • Further research into the specific mechanisms driving these changes is warranted.

Hematopoiesis01:21

Hematopoiesis

The process of blood cell formation is called hematopoiesis. Hematopoiesis starts early during development, on the seventh day of embryogenesis. This phase of hematopoiesis is called the primitive wave, wherein the extraembryonic yolk sac allows the production of erythroid cells and endothelial cells from a common precursor called hemangioblast. The erythroid cells provide oxygen to support the growth of the rapidly dividing embryo. Hemangioblasts later develop into hematopoietic stem cells or...
Multipotency of Hematopoietic Stem Cells01:19

Multipotency of Hematopoietic Stem Cells

The hematopoietic stem cells or HSCs are multipotent, meaning they can differentiate and give rise to all blood and immune cells. HSCs are maintained in the quiescent stage until an external stimulus initiates their differentiation. The multipotent HSCs exist as two heterogeneous populations, long-term repopulating cells (LTRC) and short-term repopulating cells (STRC). The two HSC populations have different surface markers or receptors and are classified based on quiescence and long-term...

Regulation of Hematopoietic Stem Cells

All blood and immune cells are produced from the multipotent hematopoietic stem cells (HSCs) by the process of hematopoiesis. However, they all have a limited life span. In addition, many are depleted in immune surveillance or combatting an injury or infection. This makes blood one of the most regenerative tissues. Hematopoiesis helps replenish these blood and immune cells, restoring the body's normal functioning. However, overproduction of blood and immune cells can make them cancerous or...
Overview of Hematopoiesis01:20

Overview of Hematopoiesis

Hematopoiesis, or blood cell production, is a vital biological process that begins early in embryonic development and continues throughout life. This process generates the various types of cells found in blood, including red blood cells, white blood cells, and platelets from hematopoietic stem cells (HSCs).
Developmental Phases of Hematopoiesis
Initially, HSCs are formed in the embryonic yolk sac, a critical site for early blood cell production. These stem cells subsequently migrate to other...
Role of Hematopoietic Growth Factors01:28

Role of Hematopoietic Growth Factors

Hematopoietic growth factors are molecules that regulate the differentiation rate of hematopoietic stem cells (HSCs). Erythropoietin (EPO), primarily produced by the kidneys, plays a crucial role in erythrocyte production. When oxygen levels in the blood are low, EPO is released into the bloodstream, reaching the bone marrow, where it stimulates HSCs to differentiate and mature into erythrocytes, which are vital for oxygen transport.
Thrombopoietin (TPO), mainly released by the liver,...
