Abstract:Lung development depends on accurate and precise patterning of a pulmonary anlagen, consisting of both endodermally and mesodermally derived progenitor cells. In this process, the need to establish communication and control among individual cells is paramount. Transforming growth factor-β (TGFβ) and Wingless/int (Wnt) signaling pathways serve this need. The individual functional repertoire of the two pathways is further expanded by cross-talk and integration of signaling at multiple levels taking advantage of their hard-wired multi-component signal transduction platforms. Cross-talk creates the possibility for both specificity and versatility in signaling during development and during repair of injured tissue. Understanding the mechanics and the physiological implications of this cross-talk is necessary for therapeutic or preventive targeting of either TGFβ or Wnt signaling pathways.
