Chitosan cooperates with mesenchyme-derived factors inregulating salivary gland epithelial morphogenesis

Chitosan is a widely used biocompatible biomaterial in the tissue regeneration, but its utility and application in the tissue morphogenesis of salivary gland remains unclear. The study aimed to explore the effects of chitosan on the epithelial morphogenesis of submandibular gland (SMG). With chitosan, the branching morphogenesis of the whole SMG explant was facilitated, and the morphogenetic-pr...

Determination of the curvature of epithelial cell mass by mesenchyme in branching morphogenesis of mouse salivary gland.

Mouse submaxillary epithelium undergoes branching morphogenesis with increase in the curvature of its surface in vivo. Recombination experiments in vitro of the epithelium and mesenchyme between 13- and 14-day rudiments showed (1) that the 14-day mesenchyme more actively induced the epithelium to branch than the 13-day mesenchyme, (2) that the 14-day mesenchyme could produce clefts on smaller e...

Embryonic Salivary Gland Branching Morphogenesis

Salivary submandibular gland (SMG) morphogenesis is regulated by the functional integration of stage-specific growth factor, cytokineand transcription factor-mediated signaling which mediates specific patterns of cell proliferation, cell quiescence, apoptosis, and histodifferentiation. We describe the stage-specific distribution of protein components of key signaling pathways during embryonic S...

A role for mesenchyme-derived tachykinins in tooth and mammary gland morphogenesis.

Tachykinin peptides such as substance P (SP) function as neurotransmitters and neuromodulators in the mammalian central and peripheral nervous systems. Here, we provide evidence that they may also play an important role in the morphogenesis of some nonneural organs where epithelial-mesenchymal interactions are involved. We show the following. (1) mRNA encoding tachykinin precursor proteins is e...
