A dynamic and reciprocal flow of information between cells and the extracellular matrix contributes significantly to the regulation of form and function in developing systems. Signals generated by the extracellular matrix do not act in isolation. Instead, they are processed within the context of global signalling hierarchies whose constituent inputs and outputs are constantly modulated by all the factors present in the cell's surrounding microenvironment. This is particularly evident in the mammary gland, where the construction and subsequent destruction of such a hierarchy regulates changes in tissue-specific gene expression, morphogenesis and apoptosis during each developmental cycle of pregnancy, lactation and involution.
细胞与细胞外基质之间动态且相互的信息流,对发育系统中形态和功能的调节起着重要作用。细胞外基质产生的信号并非孤立起作用。相反,它们是在全局信号层级的背景下进行处理的,该层级的组成输入和输出会不断受到细胞周围微环境中所有因素的调节。这在乳腺中尤为明显,在怀孕、哺乳和退化的每个发育周期中,这样一个层级的构建和随后的破坏调节着组织特异性基因表达、形态发生和细胞凋亡的变化。
