Myeloblast blood cell, light micrograph
Myeloblast blood cell. Light micrograph of blood cells, including a myeloblast, a precursor for a type of white blood cell (leucocyte). Myeloblasts differentiate into granulocytes

Promyelocyte blood cell, light micrograph. This blood cell (centre) is a precursor for a type of white blood cell called a granulocyte, formed by granulopoiesis in the bone marrow

Haematopoietic stem cells, artwork
Haematopoietic stem cells. Cutaway computer artwork showing white blood cells (leucocytes, white, round), red blood cells (erythrocytes, red) and haematopoietic stem cells (HSCs)

Erythroblast blood cell, light micrograph
Erythroblast blood cell. Light micrograph of cells from a sample of bone marrow, including a polychromatic erythroblast (upper left). This one has multiple cell nuclei (dark red, four in total)

Blood cells, illustration C018 / 0802
Blood cells. All cellular blood components originate from the same cell, the haematopoietic stem cell. The stem cell differentiates into two types of progenitor cells

Haematopoietic stem cell, SEM C013 / 5008
Haematopoietic stem cell, coloured scanning electron micrograph (SEM). Stem cells can differentiate into any other cell type

Haematopoietic stem cell, SEM C013 / 5007
Haematopoietic stem cell, coloured scanning electron micrograph (SEM). Stem cells can differentiate into any other cell type

Haematopoietic stem cell, SEM C013 / 5006
Haematopoietic stem cell, coloured scanning electron micrograph (SEM). Stem cells can differentiate into any other cell type

Bone marrow stem cell, SEM
Bone marrow stem cell, coloured scanning electron micrograph (SEM). This cell is known as a multipotential stem cell because it can form the precursors to every type of blood cell

"Unlocking the Secrets of Haematopoiesis: Journey into Blood Cell Formation" Haematopoiesis, the intricate process by which blood cells are formed, is a captivating phenomenon that occurs within our bodies. Stem cells, depicted in stunning detail through scanning electron microscopy (SEM), play a crucial role in this remarkable journey. In one mesmerizing SEM image, we witness the elegance of haematopoietic stem cells (HSCs) as they navigate their way through the complex network of bone marrow. These versatile HSCs possess an extraordinary ability to differentiate into various types of blood cells, ensuring our body's constant supply. Under the lens of a light microscope, myeloblast and promyelocyte blood cells come alive with vibrant colors and distinct features. These early stages showcase the transformation from HSCs to specialized cell lineages responsible for immune defense and clotting mechanisms. Artwork beautifully captures the essence of haematopoietic stem cells at work - orchestrating a symphony of cellular development within our bodies. Their tireless efforts give rise to erythroblast blood cells, captured in multiple light micrographs with breathtaking clarity. These erythroblasts carry oxygen throughout our system while maintaining their unique biconcave shape. Illustrations further illustrate this fascinating process; depicting diverse blood cell populations working harmoniously together to ensure optimal health and vitality. Each individual component plays its part - red blood cells delivering oxygen, white blood cells defending against pathogens, and platelets aiding in clot formation. Returning once again to SEM imagery, we delve deeper into the world as it unfolds before us. The resilience and adaptability displayed by these haematopoietic stem cells are truly awe-inspiring – each image capturing their intricate structures and delicate balance between self-renewal and differentiation.
