tübüllerin

Tübüllerin is a term used in theoretical biology to describe a proposed class of tubular units that form networks in computer simulations of morphogenesis and transport processes. The concept is not an established taxon or a documented organism; it is a model-based construct used to explore how simple tubular modules might coordinate growth and substance movement in hypothetical systems.

In the imagined framework, tübüllerin are hollow, tube-like elements with flexible walls. They assemble by growth at their tips and can connect with nearby tubes through lateral fusion, creating reticulate, lattice-like networks. The tubes are envisioned as capable of transporting small molecules and signals along their interior and along the network as a whole, through diffusion and advective flow driven by network topology.

Dimensions in model descriptions typically place tübüllerin in the micrometer scale, with diameters around half a micrometer to two micrometers and lengths spanning several micrometers. Network density and connectivity are adjustable parameters, allowing researchers to study how changes in tube stability, fusion rules, and growth rates affect overall transport efficiency and robustness.

Applications of the concept include illustrating how modular tubular elements could support material exchange, signaling, or structural coordination in synthetic tissues, prebiotic systems, or abstract ecological models. Because the idea rests on hypothetical rules rather than empirical data, it remains a speculative tool. Critics note that care is needed to avoid conflating tübüllerin with real cellular tubules or extracellular matrix networks; the term is primarily used to test ideas about network formation and transport in simplified settings.
