Intero Raises $2.3M to Commercialize Lab-Grown Gut Model for Drug Testing

Intero Biosystems raised $2.3 million in pre-seed funding to sell GastroScreen, its millimeter-scale lab-grown human gut model for preclinical testing of drugs, foods and chemicals. The Denver company, a 2024 University of Michigan spinout, will sell the model with chemical kits or as contract studies, offering drugmakers an alternative to animal tests as the FDA shifts toward non-animal methods.
