Tissue stretch decreases soluble TCF-betal and type-1 procollagen in mouse subcutaneous connective tissue: evidence from ex vivo and in vivo models.
In conclusion, the findings of this study collectively provide compelling evidence that differentiated keratinocytes release collagenase-stimulatory 14-3-3s protein for dermal fibroblasts and that this may in turn control degradation of the major dermal ECM components such as type I and type III procollagen.
