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].

We describe the isolation of neonatal cardiomyocytes and the preparation of the cells for encapsulation in fibrin hydrogel constructs for tissue engineering. We describe methods for analyzing the tissue engineered myocardium after the culture period including active force generated upon electrical stimulation and cell viability and immunohistological staining.
FAQs
Architecture is set by the mold’s cavity or patterned framework before the construct material becomes stable. Confinement fixes overall geometry and size, while internal features in the template can establish pores, channels, or layers. As the biomaterial, cell-laden hydrogel, or tissue construct cures, gels, or solidifies, those imposed boundaries help preserve the intended organization.
Pores, channels, and layers give researchers ways to reproduce selected architectural features of native tissues rather than controlling only the construct’s outer shape. These features also organize the material internally, which matters when building reproducible models for cell-behavior studies, biomaterial testing, and engineered-tissue development. Their value lies in linking physical design with the biological context being investigated.
The mold’s cavity determines the construct’s overall form and dimensions, while patterned regions determine internal organization. Adding pore, channel, or layered features changes which aspects of tissue architecture the model can represent. Consistent template geometry also improves reproducibility across constructs, allowing researchers to compare cell behavior, biomaterials, or tissue-development outcomes under more controlled structural conditions.
During fabrication, the selected material is confined within the mold’s cavity or framework. The template maintains the desired boundaries while the material cures, gels, or solidifies, converting a temporarily shaped mass into a construct with defined geometry. This sequence connects processing conditions with the final architecture and helps produce repeatable scaffold designs.
These molds can shape biomaterials, hydrogels containing cells, and developing tissue constructs. The choice depends on what researchers are trying to organize: a material scaffold, a living cell-laden system, or tissue as it develops. Because the same templating principle accommodates these forms, molds serve as a shared fabrication strategy across several bioengineering model types.
Researchers can use molded constructs to study how cells behave within a defined three-dimensional architecture, evaluate biomaterials, and develop engineered tissues. Their controlled geometry supports reproducible models for comparing experimental designs. In regenerative medicine, these constructs provide a way to investigate tissue configurations that include selected native features such as pores, channels, or layers.
Within bioengineering, the main value is the connection between physical form and biological investigation. A mold can encode selected features of native tissue architecture, then provide a consistent platform for examining cells, biomaterials, or tissue development. This makes the approach relevant both to basic studies of construct organization and to regenerative-medicine efforts involving engineered tissues.
