Polyurethane-based platforms for hair follicle evaluation

Overview

Current in vitro and ex vivo hair follicle models often fail to accurately mimic the scalp's complex environment, limiting their effectiveness in testing hair growth treatments. This research from North Carolina A&T State University presents a novel polyurethane-based hydrogel coating system designed to replicate key features of the scalp, such as hydration, permeability, and mechanical support. By stabilizing ex vivo human hair follicle models, this platform enables reproducible and quantitative evaluation of hair growth-modulating compounds, enhancing the translational relevance of test results.

Technical specifications

Key features:

• Polyurethane-based hydrogel coatings: These coatings mimic the hydrated, mechanically supportive, and permeability-controlled environment of the scalp.
• Enhanced hair follicle model: The system stabilizes and maintains the native structure and function of ex vivo human hair follicles, allowing for accurate evaluation of hair growth treatments.
• Topical delivery strategies: Integration with moderate-throughput screening formats enables the simultaneous evaluation of multiple hair growth treatments.
• Analytical tools: Utilizes analytical chemistry to quantify diffusion and release kinetics, linking material behavior with biological responses.

Technology readiness level

This technology is currently at Technology Readiness Level 2, indicating that the concept has been formulated and basic principles have been observed in a laboratory setting. Future work includes developing an ex vivo human hair follicle culture model and engineering tunable hydrogel coatings to further validate the system.
