Skin & Tissue Equivalent Models
Skin and tissue equivalent models are engineered in-vitro systems designed to mimic the structure, function, and biological behavior of human tissues. These models provide a controlled, physiologically relevant environment for evaluating biomaterials, medical devices, pharmaceuticals, cosmetics, wound-care products, and tissue-engineering strategies, without requiring immediate in-vivo testing. By replicating key features of human tissues such as epidermal and dermal layers, extracellular matrix (ECM), vascularization cues, barrier properties, and cellular interactions, these models enable accurate assessment of biocompatibility, irritation potential, healing response, barrier integrity, and regenerative capability.
Materials Metric develops and characterizes custom soft- and hard-tissue equivalents, enabling high-quality data for R&D decision-making, product optimization, safety assessment, and regulatory submissions across biomedical, dental, pharmaceutical, and materials science applications.
