In cooperation with the Institute of Biophysics of the Czech Academy of Sciences, researchers in Zlin purpose to create laboratory-grown tissue that carefully mimics the actual small intestine and will assist drug growth and analysis into intestinal ailments with out the want for animal testing.
Petr Humpolíček is head of the analysis crew.
“When you want to test medicines today, you basically have two options. Either you test on animals, or you try to avoid it, which is the goal of virtually the entire scientific community,” he says.
According to Humpolíček, many human tissues can already be produced with such precision that animal testing is not crucial.
“Tests on eye tissue or lung mucosa no longer have to be carried out on animals; researchers can use an in vitro model instead. Intestinal tissue, however, is significantly more complex than other tissues or mucous membranes, which is why researchers have been using animals. Our primary goal is to make the model as real as possible and technologically simple enough so that researchers can easily make it themselves in their own laboratories.”
To make the model as reasonable as potential, scientists first must create an atmosphere primarily based on a simplified gel construction comprised of numerous biopolymers. This entails pretty demanding chemistry and the gel must be structured to imitate the inner construction of the intestine.
Researchers produce particular moulds utilizing 3D printers, that are used to imprint microscopic protrusions and indentations into the gel to duplicate the intestine’s interior structure.
The subsequent step is to mix fundamental tissue construction with immune cells in addition to microorganisms generally discovered in the intestine.
“Once the gel is ready, we can insert human cells into it, add immune cells, and because we want it to be as realistic as possible, we also want to include a microbial population, commonly referred to as the microbiome. The goal is to create a system that faithfully reproduces the behaviour of intestinal tissue under various conditions during scientific experiments. This ranges from understanding how substances are absorbed in the intestine, through studying drugs that pass through the intestinal wall, to research into diseases affecting the intestine,” Humpolíček says.
The challenge has obtained 11 million crowns in funding from the Czech Science Foundation, and the accomplished model of the human small intestine is anticipated to be introduced at the finish of 2027.
