软体动物贝壳中的有机基质具有调节碳酸钙沉积和结晶的潜力。因此，晶体生长的控制似乎依赖于对套细胞中基质蛋白分泌或激活过程的控制，而这一点人们知之甚少。生物矿化是一个高度协调的生物过程。这项工作的目的是提供关于外套膜外上皮内壳基质大分子产生的来源的信息。选择活体方法来描述外上皮和血窦分布的组织学变化，这些变化与外壳基质的产生有关。我们的结果描述了参与鲍壳生物矿化的基质蛋白在鲍地幔中的地形和随时间变化的区带。
Organic matrix from molluscan shells has the potential to regulate calcium carbonate deposition and crystallization. Control of crystal growth thus seems to depend on control of matrix protein secretion or activation processes in the mantle cells, about which little is known. Biomineralization is a highly orchestrated biological process. The aim of this work was to provide information about the Source of shell matrix macromolecule production, within the external epithelium of the mantle. An in vivo approach was chosen to describe the histologic changes in the outer epithelium and in blood sinus distribution, associated with mantle cells implicated in shell matrix production. Our results characterized a topographic and time-dependent zonation of matrix proteins involved in shell biomineralization in the mantle of Haliotis.
