全身纤维结缔组织网络中的界面流体传输现象

【摘要】：纤维结缔组织在身体中的作用是支撑、连接和分隔不同的组织和器官。最近,人体断肢解剖研究证实,一种定向纤维结缔组织组成了一种长程液体传输通路。其解剖位置有两种:皮肤传输通路(包括真皮、皮下组织和脂肪小叶间隔)和血管周围传输通路(静脉和动脉周围纤维结缔组织)。这种纤维通路的三维空间内部结构是一种纵向分布、相互连接的纤维丝,在每一根纤维丝及其周围水凝胶之间形成了一种固液界面区;纤维结缔组织中的液体能够通过这种界面区传输,命名为"生物界面流体传输通路";存在于各种组织和器官纤维基质中的液体,很可能并没有被束缚在"组织凝胶"中,而是在尚未明确的某种物理机制的作用下,朝向一定的方向传输。这些研究结果为理解纤维结缔组织的功能提供了一个新的视角。
[Abstract]:The role of fibrous connective tissue in the body is to support, connect, and separate different tissues and organs. Recently, anatomical studies of human amputated limbs have confirmed that a directional fibrous connective tissue forms a long-range liquid transport pathway. There are two anatomical sites: the cutaneous transmission pathway (including dermis, subcutaneous tissue and fat interlobular septum) and the perivascular transmission pathway (vein and periarterial fibrous connective tissue). The three-dimensional internal structure of the fiber pathway is a longitudinal distribution of the interlinked fiber filament, forming a solid-liquid interface between each fiber filament and its surrounding hydrogel. Liquids in fibrous connective tissues can be transported through this interfacial region, known as the "biological interface fluid transport pathway"; liquids found in various tissue and organ fibrous matrices are probably not bound to "tissue gels." Rather, it is transmitted in a certain direction under the action of some undefined physical mechanism. These findings provide a new perspective for understanding the function of fibrous connective tissue.
