2013
The generation of aligned myocardial tissue is a key requirement for adapting the recent advances in stem cell biology to clinically useful purposes. Herein we describe a microcontact printing approach for the precise control of cell shape and function. Using highly purified populations of embryonic stem cell derived cardiac progenitors, we then generate anisotropic functional myocardial tissue.

We showcase the development of self-assembled, three-dimensional bundles of longitudinally aligned astrocytic somata and processes within a novel biomaterial encasement. These engineered "living scaffolds", exhibiting micron-scale diameter yet extending centimeters in length, may serve as test-beds to study neurodevelopmental mechanisms or facilitate neuroregeneration by directing neuronal migration and/or axonal pathfinding.

2025
The alignment of a road line using Geographic Information Systems (GIS) is a critical process in civil engineering, combining advanced technology with practical decision-making. This methodology begins with the collection of geospatial data, including information on land cover, geomorphology, drainage patterns, slope, and contour details. Such data is typically acquired through satellite imagery and GIS tools, offering a comprehensive understanding of the terrain.Once the data is gathered, it...
FAQs
Physical cues create directional information that cells can translate into organized behavior. Patterned substrates and aligned biomaterials provide an oriented setting, while fluid shear, mechanical strain, and electrical stimulation impose additional directional inputs. These signals influence cell adhesion and migration and reshape cytoskeletal organization, allowing cellular structure to follow the intended axis. This coupling is central to engineered tissue architecture.
Patterned substrates and aligned biomaterials encode orientation through the architecture that cells contact. Fluid shear and mechanical strain instead provide controlled physical loading, while electrical stimulation supplies a directional signal. Because these approaches act through different types of cues, researchers can relate the selected stimulus to cellular adhesion, migration, and cytoskeletal organization when designing an aligned construct.
Cytoskeletal organization links an external directional cue to the cell’s internal structure. As cells adhere and migrate in response to patterned surfaces, aligned materials, fluid shear, strain, or electrical stimulation, their cytoskeleton can become organized along the imposed direction. That organization helps build tissue architectures in which direction-dependent structure supports force transmission or signal conduction, both important bioengineering targets.
A suitable strategy starts with the function and architecture that a construct should reproduce. If direction-dependent force transmission is central, the design can emphasize alignment relevant to muscle, tendon, or ligament; nerve and other tissues provide additional contexts for organized architecture. Researchers then select among substrate, biomaterial, fluid, mechanical, or electrical cues to guide the desired cellular response.
Aligned architectures are especially relevant to engineered muscle, nerve, tendon, ligament, and vascular tissues. In these systems, organizing cells or structural materials along defined directions can improve how the construct reproduces native tissue organization. The resulting design may support tissue-level functions associated with directional structure, including force transmission or signal conduction, depending on the biological context.
Beyond constructing replacement tissues, these methods support biomimetic models, regenerative therapies, and studies of tissue development and repair. Aligned architectures let investigators examine how material design affects cellular behavior while creating structures that more closely reproduce native tissue organization. Their value therefore spans mechanism-focused studies of cell responses and function-oriented efforts to improve engineered tissue performance.
