Students of metazoan biology have traditionally viewed the extracellular matrix (ECM) as a substrate with which cells interact to participate in developmental pattern formation and define a specific location. In contrast, the plant cell wall has been viewed as a cage that limits and thus directs plant cell morphology, and perhaps for this reason many have shied away from calling the plant cell wall the ECM. The recent discovery of a variety of receptor molecules and their ligands on the surface of plant cells and the intimate role cell walls play in development should direct our thinking toward a more dynamic view of the plant cell wall. A recent example, is the discovery of wall associated kinases (WAKs), which may well signal between the ECM and the cell and are required for cell expansion.
后生动物生物学的学生传统上认为细胞外基质（ECM）是一种细胞与之相互作用以参与发育模式形成并确定特定位置的底物。相比之下，植物细胞壁一直被视为一个限制并因此指导植物细胞形态的牢笼，也许正是因为这个原因，许多人一直不愿将植物细胞壁称为细胞外基质。最近在植物细胞表面发现了多种受体分子及其配体，以及细胞壁在发育中所起的密切作用，这应该引导我们以更动态的视角看待植物细胞壁。最近的一个例子是发现了壁相关激酶（WAKs），它们很可能在细胞外基质和细胞之间传递信号，并且是细胞扩张所必需的。
