N2 - The c-fes protein (NCP92) is a tyrosine-specific protein kinase, capable of both autophosphorylation and phosphorylation of other substrates. We have analysed c-fes RNA expression in human/murine ontogenetic development and in homogenous populations of embryonic and adult human hematopoietic cells. c-fes expression has been observed in rapidly proliferating embryonic-fetal tissues originating from different germinal layers, but not in adult non-hematopoietic tissues. In particular, a spatially and temporally regulated transcription was observed in the central nervous system and in developing cartilage. Expression in hematopoietic cells was evaluated in progenitors purified from embryonic-fetal liver and adult peripheral blood differentiating gradually and specifically along the erythroid or granulomonocytic lineage. In both embryonic and adult hematopoietic cells c-fes was abundantly expressed in undifferentiated progenitors of both lineages, as well as in differentiated granulomonocytic precursors, but not in erythroblasts. This expression pattern correlates with that of GM-CSF and in part IL-3 receptors. Altogether, these results suggest a possible role for c-fes in signal transduction, in both embryonic non-hematopoietic tissues and embryonic/adult hematopoietic cells, following interaction of growth factors with their tyrosine-kinase negative receptors (i.e., GM-CSF and IL-3 receptors in adult hematopoietic cells and other hypothetical growth factor(s) receptors during embryonic development).
