PROTEIN SCAFFOLD ORGAN HOW TO

This has resulted in a wide and growing array of non-scaffold-based growth options. Scaffold-Free Options Are GrowingĪs scientists have identified the limitations for scaffold-based growth, they have simultaneously invented new techniques to get the results they need. Organoid models often employ protein scaffolds to help cells grow properly throughout the test environment.ĭifferent cellular scaffoldings allow different cellular processes to proceed healthily and provide meaningful experimental data about in vivo behavior. That's why cellular growth scaffolds now come in a wide variety of forms, such as hydrogels, permeable support wells, and electrospun fibrous scaffolds - to better provide analogues for the wide variety of cell types in the body. Many processes rely on the extracellular matrix to proceed properly, but many do not - in particular many diseased cells that require specifically this type of research. Cells can also adhere to the protein matrix in some of these gels, and, as they grow along them, become less representative of real biological proliferation. In particular, hydrogels are mostly homogeneous, meaning that they might not always mimic the gradients of in vivo conditions that real cells experience. This provides the perfect environment for 3D culturing of many cell types, providing an environment similar to in vivo biological conditions.īut there are limitations. Recently, labs have made incredible breakthroughs through the use of certain substances - hydrogels, in particular - to maintain a stable protein matrix that can mimic the extracellular matrix of a living animal. Over time, the hope is to create such a wide variety of highly specific growth analogues that virtually any biological condition can be recreated through a piecemeal recreation of each cell and tissue type that hierarchically governs in vivo cellular function. Knowing the differences is crucial to saving time and money and avoiding the frustration of rerunning failed trials. Some applications favor the scaffold-based approach others are best-suited for a scaffold-free platform. Recent years have seen the emergence of a wide variety of non-scaffold-based approaches to 3D cell culturing and tissue engineering that offer benefits over - but also limitations not found in - scaffold-based alternatives. One of the biggest breakthroughs in this process has been the use of cellular scaffolding to provide a structure on which growth can proceed in an organized fashion.

Since the beginning of biomedical science, one of researchers' primary goals has been figuring out how to progress cell culturing from growing cells to growing the tissues composed of these cells to growing the organs composed of these tissues.
