Preclinical Model
An experimental system (cell culture, animal model, or ex vivo preparation) used to study compound effects before advancing to human clinical research.
Definition
A preclinical model is any experimental system used to study the biological activity, safety, and pharmacological properties of a compound before human studies. Preclinical models span a continuum from simple biochemical assays and cell culture systems (in vitro) to complex organism-level experiments in animals (in vivo). Common preclinical model types include immortalized cell lines, primary cell cultures, organoids, genetically modified mouse models (knockouts, transgenics), surgical injury models (tendon transection, spinal cord injury, myocardial infarction), disease induction models (colitis, tumor xenografts), and aging models (aged rodents, accelerated aging genetic models).
Research Context
Preclinical model selection is a critical decision in research peptide studies because the relevance and translatability of findings depend on how well the model captures the biological processes of interest. For tissue repair research, surgically induced injury models in rodents are standard. For metabolic research, diet-induced obesity models or genetic models of insulin resistance are used. For aging research, naturally aged cohorts or genetic progeroid models are employed. Understanding the strengths and limitations of each preclinical model is essential for correctly interpreting published research peptide literature.
