This Embryology category shows pages and media related to blood and blood development (ehmatopoiesis). The website also includes information on blood cell and bone marrow histology and the immune system.


Blood is a liquid connective tissue, its development begins in mesoderm inside the embryo as well as in extra embryonic mesoderm associated with the yolk sac and chorion. Mesoderm "blood islands" form both the vessel wall (endothelium) and the inner part forms blood stem cells. The blood stem cells initially form mainly fetal red blood cells that have their own specific haemoglobin.

During development these blood stem cells transiently relocate to different tissues (liver, spleen, thymus) until the cartilaginous skeleton has begun to form bone when they then relocate into the developing bone marrow (their future permanent home). Recently, placental cord blood has become an important clinical source of stem cells and cord blood banking a significant resource.

Note that a modified form of blood plasma, cerebrospinal fluid (CSF), is manufactured by the choroid plexus to fill the central nervous system ventricular system.
