longweefselfunctie

Longweefselfunctie is a theoretical concept in systems biology that describes the emergence of self-regulating function within elongated tissue networks. It proposes that local interactions among cells, the extracellular matrix, and mechanical cues can coordinate to produce distributed control over tissue-wide processes without a centralized governing unit.

The term combines elements from Dutch into a single concept, with “weef” referring to tissue and “zelf functie” to self-function. In long, thread-like networks such as vascular trees, smooth muscle layers, neural tracts, or engineered fibrous scaffolds, network topology, feedback loops, and signaling gradients can enable adaptive responses along the length of the tissue. This can manifest as coordinated contractility, remodeling, or homeostatic maintenance that operates across kilovolt- or millimeter-scale dimensions, depending on the system.

The concept is typically explored through theoretical modeling, simulations, and experiments in organ-on-a-chip or tissue-engineering contexts. Researchers investigate how simple, local rules give rise to global behavior, and how changes in network structure or signaling dynamics affect emergent regulation. Key questions include defining operational metrics for LWSF, distinguishing it from classic feedback mechanisms, and identifying conditions under which long-range coordination is robust to perturbations.

Longweefselfunctie remains a debated and exploratory term rather than a widely established doctrine. It serves as a lens for examining how long-range coordination might arise in tissue networks, complementing broader ideas of self-organization and emergent phenomena in biology.
