Special Issue Information

Dear Colleagues,

The concept of fascia is currently widely used in therapeutics and is based on an anatomical definition which is difficult to correspond to the reality observed, especially after explorations of the living human body.

In fact, there are two opposing concepts: one which is in the descriptive macroscopic anatomical tradition made on the cadaver or on the isolated fragment, and the other is the result of recent endoscopic observations of the living human body or the outcome of reflections on other scientific fields.

One defines the body in terms of separate organs connected by layers of more or less flexible tissue, visible in layers and called fascia or connective tissue. The other gives connective tissue or fascia a more important role, that of architecting the body, giving it its shape because it exists at all scales, from macroscopic to mesoscopic to microscopic as a huge network.

In this Special Issue, I propose a review of the current status of these two ways of perceiving the concept of fascia, firstly by making a definitive link between fascia, connective tissue, and the extracellular matrix, because inevitably words are different, but the observed reality brings them closer together. We will also be looking at the other sciences involved in the human body, cellular and extracellular biochemistry, embryology, thermodynamics, fluids, quantum physics, and complex systems.

I invite all those who wish to contribute to the clarification of this semantic difficulty to submit their articles (original research, reviews) to this Special Issue.

Intra-tissue endoscopy, providing real-time images at all scales, from macroscopic to microscopic, from inside living tissue during surgical procedures, has revealed the existence of a body-wide fibrillar architecture that extends from the surface of the skin to the cell. Different types of cells are housed within this fibrillar architecture and gather together to carry out specific functions. This challenges the commonly accepted notion of the organization of living matter that associates separate organs with connective tissue packaging. We are thus confronted with the global nature of the living human body and its vital processes. This paper sets out to describe the architecture of this fibrillar network which could be assimilated with the fascial tissue and which attributes a more constitutive role to connective tissue. It also demonstrates how movements within this fibrillar network can occur with minimal local distortion while maintaining tissue continuity. The authors propose that the gliding of tissues can be explained by the existence of a highly adaptable fibrillar network that enables the gliding of distinct anatomical structures such as tendons and muscles, without any dynamic influence on the surrounding tissues. The authors propose a new model of tissue movement based on the observation of a ubiquitous dynamic polyhedric fibrillar network with an apparently dispersed and complex pattern of organization, that forms fluid-filled microvolumes, and is found everywhere in the human body. Furthermore, this fibrillar network appears to act as a force absorption system, in addition to providing a framework or scaffolding for cells throughout the body. Observation during intra-tissue endoscopy suggests that this fundamental architectural organization extends into the extracellular matrix that is the natural environment of all cells in the living body, regardless of their size, location or specific function.
