Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain haematopoiesis and its stages, relate it to blood disorders and transplantation in general terms, and support learning and research.

The formation of blood cells from haematopoietic stem cells, occurring in the embryo in the yolk sac and liver and after birth mainly in the bone marrow, producing red cells, white cells and platelets through lineage-specific pathways such as erythropoiesis and megakaryopoiesis; disorders of haematopoiesis include anaemias, leukaemias and marrow failure, and it is harnessed in stem cell transplantation.

What it is for: Haematology, physiology and medicine.

It can be explain lineages and stages; describe embryonic and adult haematopoiesis; relate haematopoiesis to disorders in general terms; explain stem cell transplantation.

Distinguishing features

Stem cell driven

Lineage hierarchy

Site changes through development

Regulated by cytokines

What it looks like

Not visible; cellular processes in marrow and embryonic tissues.

How it is recognised

Stem cells differentiating into blood lineages

Bone marrow in adults

Blood itself is the product, not the process
