In 1868, Ernst Neumann recognized that blood cells re quire
continuous replenishment during postnata1life. Before him, the
assumption was that cells of the blood, like nerves once formed in
the embryo, remain in the body throughout life. Neumann also
recognized that this process occurred within the bone marrow,
because this tissue provided a fa vorable environment for
proliferation and differentiation of blood cell precursors. Vera
Danchakoff, the Russian embryologist working in the US, in 1916
made an analogy to the soil and the seed. Bone marrow forms the
soil, providing a favorable environment for the growth of seed, the
hemopoietic stem cell, and other progenitor cells. Imagine in the
remote past a heap of similar tree seeds. These seeds develop in
our moderate climate into a tall and many branched tree. Suppose
the wind bears a part of the seeds away and brings them to a land
possessing different environmental conditions, we will say the arc
tic lands. There the seeds may develop but they may pro duce trees
no higher than our moss."

Perhaps no scientific field in recent years has gained in
techniques and applications as much as molecular biology, and it is
certainly no ex aggeration to.say that among all the applications
of molecular biology, hematology in general, and hemopoiesis in
particular, have benefited most. Owing to the applications of
molecular biology, we now live in a golden era of hemopoiesis. Our
understanding of the intricate regulatory system in hemopoiesis has
vastly expanded. The potential for future exploration is ever
expanding, and finally, the possibility of gene manipulation, has
provided the promise of fundamental treatment and "cure" of many
genetic disorders involving hemopoietic cells. In the ambiance of
this rapidly moving scientific era, the necessity for review of
what is being accomplished and where the technical potential is
taking us needs no argument. This volume presents the proceedings
of the third annual symposium on the Molecular Biology of
Hemopoiesis, held in the Rye Town Hilton, New York, November 6 and
7, 1987, under the auspices of New York Medical College, Valhalla,
New York. The fact that this was the third regular symposium
covering this area in itself testifies to a need for exchange of
the rapidly developing knowledge in this area. But this third
symposium also coincided with the centennial of the National
Institutes of Health and consequently the symposium was dedicated
to this festive occasion."
