The tissue-specific extracellular matrix (ECM) is a key mediator of cell function. This article describes methods for synthesizing pure ECM-derived foams and microcarriers that are stable in culture without the need for chemical crosslinking for applications in advanced 3D in vitro cell culture models or as pro-regenerative bioscaffolds.

We propose a cell expansion protocol on macroporous microcarriers and their use as delivery system in a perfusion bioreactor to seed a decellularized tissue matrix. We also include different techniques to determine cell proliferation and viability of cells cultured on microcarriers. Furthermore, we demonstrate functionality of cells after bioreactor cultures.
FAQs
The particles provide attachment area within the culture vessel, allowing anchorage-dependent cells to occupy more growth-supporting surface than the vessel alone would provide. As attached cells proliferate, the available surface area helps maintain many cells in a limited liquid volume. This arrangement is especially relevant when researchers need to increase cell numbers without proportionally increasing vessel size.
Gentle agitation keeps the particles distributed through the medium rather than allowing them to remain in one location. That movement promotes more uniform exposure to nutrients and oxygen and helps cells on different particles experience similar culture conditions. The process suspends the carriers while maintaining the attached-cell environment needed for scalable growth.
Attachment to the particle surface gives anchorage-dependent cells a physical site for growth while the surrounding medium supplies the culture environment. The particles may be porous or nonporous, so Cytodex formats can differ in physical structure even though both provide cell-supporting surfaces. This organization distinguishes the culture from systems in which cells grow only as freely suspended cells.
They add cell-supporting surface area inside the existing culture volume. Because cells attach to many particles, the available growth area can rise while the vessel dimensions remain limited. Agitation distributes those particles through the medium, linking increased surface capacity with nutrient and oxygen access. The result is a practical way to maintain larger cell populations in a compact culture setup.
A basic workflow begins by bringing anchorage-dependent cells into contact with the carriers and culture medium, allowing attachment, and then maintaining the particles under gentle agitation as the cells proliferate. The key operating features are the cell-carrier interaction, suspended particle distribution, and continued medium exposure. Together, they support a controlled transition from attachment to expanded culture.
Researchers may choose this approach when a conventional vessel does not provide enough surface area for the desired cell population or when they need a scalable culture format. In biology, the method supports mammalian-cell cultivation for vaccine production, recombinant protein expression, and cell-based research. It therefore connects small-scale cell maintenance with applications requiring greater culture capacity.
The culture can provide expanded populations of anchorage-dependent cells while retaining their association with a defined particle surface. Depending on the research goal, those cells may support vaccine production, recombinant protein expression, cell-based experiments, or tissue-engineering studies. The important outcome is a higher-capacity culture arrangement that can be evaluated for downstream biological work.
They provide a cell-supporting surface and a way to maintain attached cells in an agitated, limited-volume culture. That combination can help tissue-engineering researchers investigate cell growth under conditions offering more surface area than the vessel alone. The approach is relevant when experiments require expanded attached-cell cultures rather than relying only on the surfaces of conventional culture vessels.
