For one example, in mice with diet-induced diabetes that is an experimental equivalent of type 2 diabetes in humans, a single injection of the FGF1 protein is enough to restore blood sugar levels to a healthy range for > 2 days.
In research on diabetes, a single injection of FGF1 protein has been shown to restore blood sugar levels in mice with diet-induced diabetes, which is an experimental model for type 2 diabetes in humans.
