Description for Hematopoietic Stem Cell Differentiation Pathways Image

The image is a biological diagram showing the process of blood cell development from hematopoietic stem cells within the bone marrow. At the top, there is a cross-section of a bone labeled “Bone marrow,” indicating the site of blood formation. Below the bone, a pink circular cell is labeled “Hematopoietic stem and progenitor cell,” which serves as the origin point for two major branches of blood cell lineages.

  • Left branch: Common myeloid progenitor cell
    This branch gives rise to several cell types:
    • Megakaryocyte, a large cell that produces Platelets, shown as small red fragments.
    • Eosinophil, depicted as a pink cell with granules.
    • Basophil, shown as a purple cell with granules.
    • Erythrocytes (red blood cells), illustrated as red biconcave discs.
    • Monocyte, which further differentiates into:
      • Dendritic cell, represented as a spiky blue cell.
      • Macrophage, shown as a round blue cell.
    • Neutrophil, a purple cell with a segmented nucleus.
  • Right branch: Common lymphoid progenitor cell
    This branch produces:
    • T cell, shown as a green circular cell.
    • B cell, shown as a blue circular cell, which further differentiates into a Plasma cell, depicted as an oval blue cell with internal structures.
    • NK cell (natural killer cell), shown as a purple circular cell.

The diagram uses arrows to indicate differentiation pathways and color coding to distinguish cell types. Each cell is illustrated with unique shapes and colors to represent its identity and function.
