Here, we demonstrate fabrication of collagen-based, tissue constructs containing skeletal myoblasts. These 3-D engineered constructs may be used to replace or repair tissues in vivo. For our purposes, we have designed these as an atrioventricular electrical conduit for the repair of complete heart block[1].

This article outlines a versatile method to create cell-derived tissue rings by cellular self-assembly. Smooth muscle cells seeded into ring-shaped agarose wells aggregate and contract to form robust three-dimensional (3D) tissues within 7 days. Millimeter-scale tissue rings are conducive to mechanical testing and serve as building blocks for tissue assembly.

This manuscript presents a detailed protocol for the fabrication of an emerging three-dimensional hepatocyte culture platform, the inverted colloidal crystal scaffold, and the concomitant techniques to assess hepatocyte behavior. The size-controllable pores, interconnectivity and ability to conjugate extracellular matrix proteins to the poly(ethylene glycol) (PEG) scaffold enhance Huh-7.5 cell performance.
FAQs
Cell behavior depends on the coordinated design of cells, biomaterials, and signaling cues. Cells provide the biological activity, while the material establishes a three-dimensional setting that can support adhesion and organization. Biochemical and physical signals then influence proliferation, differentiation, and maturation. Bioengineering therefore treats the construct as an integrated cell-material environment rather than as a cell population alone.
Architecture determines how cells are positioned and how closely the construct can reproduce native tissue organization. Bioengineers can adjust material properties and three-dimensional structure to create environments suited to particular biological roles. These design choices affect cellular organization and the ability of a construct to develop tissue-like function, making architecture a central variable rather than a passive support feature.
These cues provide instructions that help cells respond to their engineered microenvironment. Their influence can guide cells toward proliferation, differentiation, or later maturation, depending on the intended tissue role. Studying these signals also lets bioengineers examine how local environments affect development and repair, linking construct design to both tissue formation and the biological mechanisms being modeled.
An engineered tissue fabrication workflow begins by selecting cells and a compatible biomaterial, then organizing them within a three-dimensional scaffold or hydrogel. Construction may use bioprinting, molding, or scaffold assembly. The resulting construct is cultured under controlled conditions that support adhesion, proliferation, differentiation, and maturation. The sequence connects physical assembly with subsequent biological development.
Culture conditions must support the progression from initial cell attachment to a more mature tissue state. In practice, the construct is maintained under controlled conditions after assembly so cells can proliferate, differentiate, and organize within the selected environment. Monitoring this stage helps determine whether the design is producing the intended biological development rather than merely creating a shaped material.
It is useful when researchers need living tissue substitutes for regenerative medicine, disease modeling, or drug testing. Constructs can also serve as experimental systems for studying how engineered microenvironments influence tissue development and repair. The appropriate design depends on the biological role being examined, so material properties, architecture, and signaling environments are tailored to the intended application.
