This protocol aims to fabricate 3D cardiac spheroids (CSs) by co-culturing cells in hanging drops. Collagen-embedded CSs are treated with doxorubicin (DOX, a cardiotoxic agent) at physiological concentrations to model heart failure. In vitro testing using DOX-treated CSs may be used to identify novel therapies for heart failure patients.

A method to create and live-image different humanized bone-marrow niches in mice is presented. Based on the supportive niche created by human mesenchymal cells, the addition of human endothelial cells induces the formation of human vessels, while the addition of rhBMP-2 induces the formation of human-mouse chimeric mature bone tissue.

We present a protocol for the antimicrobial characterization of advanced materials. Here, the antimicrobial activity on material surfaces is measured by two methods that complement each other: one is based on the agar disk diffusion test, and the other is a standard procedure based on the ISO 22196:2007 norm.
FAQs
Scaffold design determines how cells are organized and supported during tissue development. In Tissue Bioengineering, three-dimensional scaffolds provide a physical setting for attachment, proliferation, differentiation, and extracellular matrix formation, while biomaterial processing helps shape that setting. These design choices influence whether the construct can mature into a more functional biological substitute or serve as a consistent research model.
Biochemical and mechanical signals guide cell behavior in different but complementary ways. Under controlled conditions, they can influence whether cells attach, multiply, differentiate, or produce extracellular matrix. Coordinating these signals with the scaffold and biomaterial environment matters because tissue formation depends not only on which cells are present, but also on the cues they receive during maturation.
Tracking extracellular matrix formation helps evaluate whether a construct is progressing beyond simple cell presence toward tissue development. The matrix is one of the outcomes that engineered cells can produce under the influence of scaffold, biomaterial, biochemical, and mechanical conditions. In biology research, observing this process can clarify cell behavior and tissue maturation within a controlled engineered environment.
Tissue Bioengineering can function as a research platform or as a route toward a graft, depending on the intended outcome. In research, engineered tissues support studies of development, disease, and cell behavior, and they can provide drug-testing platforms. In regenerative medicine, the emphasis shifts toward restoring, maintaining, or improving tissue function, potentially reducing reliance on donor tissue.
A typical workflow brings together living cells, a biomaterial, and a three-dimensional scaffold, then exposes the construct to selected biochemical or mechanical signals under controlled conditions. Researchers can examine attachment, proliferation, differentiation, and extracellular matrix formation as the construct develops. This sequence links material processing and experimental conditions to measurable biological responses and later tissue maturation.
Choice of biomaterial and its processing affects how the scaffold presents a three-dimensional environment to cells. Researchers therefore coordinate material preparation with the intended cellular response and with the biochemical or mechanical signals applied during development. Attention to these variables is important when seeking either a useful model for experiments or a construct with improved functional-graft potential.
Drug testing is one practical application because engineered tissues provide a biological platform in which cellular responses can be studied under controlled conditions. The same systems support investigations of development, disease, and cell behavior. Their value comes from linking defined material and signaling environments with biological outcomes, allowing researchers to examine how cells respond within an engineered tissue context.
It offers a controlled setting for examining how cells interact with three-dimensional materials, respond to biochemical and mechanical signals, and form extracellular matrix. Those observations connect cellular behavior with tissue development and disease processes. At the same time, advances in scaffold design and biomaterial processing may help translate biological findings into functional grafts and lessen dependence on donor tissue.
