Research Abstract

The vertebrate spleen has important functions in immunity and haematopoiesis. We studiedearly spleen development using chicken embryo as a model animal. Gene expression patternsof seven transcription factors were examined by in situ hybridization. We found thatexpression of these transcription factors are temporally and spatially regulated duringspleen development. We also found that Fgf16, Fgf receptor-1, and -2 were expressed inthe spleen primordium. We proposed a model that FGF16-FGFR1/2 signaling controlsexpressions of transcription factors during spleen development.
