Exploring and designing scaffold materials
For cells to form tissue, it is helpful for a material scaffold to be added to provide structure. Scaffolds are crucial for cells to form tissue larger than 100µm (MacDougall 1967).
This scaffold would need to be non-toxic for the cells, edible for humans and should allow a flow of nutrients and oxygen. It must also be cheap and easy to produce on a large scale without the need for animals. Unfortunately, there is no need for such a matrix with these characteristics in the medical field so little to no research have been performed to realize this material.
