ANSWER: Hemopoiesis is the pathway of the production of blood cells from stem cells that are present in the bone marrow.
It is produced by the kidney and is involved in the regulation of synthesis of erythrocytes.
ANSWER: Interactions with the ligand Steel which is usually cell bound and is associated with cells present in bone marrow.

 Ivan Rich
Our hypothesis is that a minute population of stem cells present in the embryo is allocated to not only initiating hemopoiesis in the various hemopoietic organs during development, but is also present throughout life to maintain steady-sate hemopoiesis.
The second area of research is to study the effectiveness of primitive embryonic stem cell populations grown and expanded in vitro on the short- and long-term repopulation and of the hematopoietic system, with the view to using such cells for therapeutic transplantation purposes.
Their growth factor requirements, together with their coincident presence not only at the time definitive hemopoiesis begins, but probably also when primitive hemopoiesis is initiated, lends support for the hypothesis that the cells called primordial germ cells could actually be hemopoietic-initiating cells.

 Current Drug Targets – Inflammation & Allergy, Vol. 2, No. 4, 2003
Hemopoiesis in an allergic inflammation site differs greatly from steady-state (homeostatic) hemopoiesis in the bone-marrow, due to differences in the hemopoietic factors present, as well as on their targets.
One major aspect concerns the role of GM-CSF, which seems unnecessary for steady-state hemopoiesis in the absence of infection, but plays a central role in the immunobiology of the lungs, especially in the instructive phase of imunity, by its ability to influence dendritic cell differentiation and function.
This is changing our perception of the effects of glucocorticoids on hemopoiesis, and especially on eosinophil differentiation.

 Blood Cell Lineage
The production of formed elements, or blood cells, is called hemopoiesis.
Before birth, hemopoiesis occurs primarily in the liver and spleen, but some cells develop in the thymus, lymph nodes, and red bone marrow.
After birth, most production is limited to red bone marrow in specific regions, but some white blood cells are produced in lymphoid tissue.

 AFP: Solved and Unsolved Problems [MJM 1996 2: 127-134]
In fact, the amount of AFP in embryonal serum is higher than the initial level of serum albumin (SA), a predominant protein of late fetal and adult sera.
Later, when embryonal hemopoiesis is replaced by fetal hematopoiesis, in which the liver becomes the main site of blood formation, the synthesis of AFP and the other serum proteins is transferred to the liver.
It is well known that AFP is an obligatory component of embryonal and fetal hemopoiesis but little if anything is known regarding the nature of the association--whether it is functional, includes common regulatory links, or is only coincidental.
