Effects of hematopoietic growth factors on purified bone marrow progenitor cells

- We have used highly enriched hematopoietic progenitor cells and in-vitro culture to examine the
following questions:
1. The effects of recombinant lL-3 and GM-CSF on proliferation and differentiation of enriched
hematopoietic progenitor cells have not been clearly defined:
- how do IL~3 and GM~CSF compare with respect to number and types of colonies induced?
-to what extent do accessory cells influence colony formation induced by IL-3 and GM~CSF?
{chapters 2 and 3)
2. The effects of recombinant G-CSF, M~CSF and IL-6 on enriched hematopoietic progenitor
cells in connection with IL-3 and GM~CSF have not been fully elucidated:
~ what is the role of synergistic effects between G~CSF, M-CSF and IL~6 on the one hand
and IL~3 and GM~CSF on the other hand, on the proliferation and differentiation of colony
forming cells?
(chapters 4, 5 and 6)
3. Consistent results on the effects of ll-1 on proliferation of immature bone marrow cells are
lacking:
~does ll-1 directly induce proliferation?
-what is the role of GM~CSF and TNF as mediators of the IL-1 effect?
(chapter 7)
