Does hematopoiesis of immature myeloid dendritic cells in stroma-dependent spleen long-term cultures occur independently of NF-KB/RelB function?
Specific development of fully differentiated, but immature myeloid CD11c(+)CD11b(+)MHC-CII(-)CD8alpha(-)CD40(-) DC in spleen LTC is dependent on expression of activated NF-kappaB/Rel-B. However, this appears to relate to stromal cell function rather than to the function of hematopoietic cells. Altogether these data confirm the importance of splenic stromal cells in myelopoiesis leading to development of immature DC as produced in LTC.
Strengthening preservice laboratory education is feasible in resource-limited settings, and emphasizing its merits (ample local capacity, country ownership and sustainability) provides a valuable source of competent laboratory technologists to relieve an overstretched healthcare system.
