Summary
Researchers developed novel microspheric skin organoids using spinning bioreactors for effective high-throughput drug screening. These organoids mimic human skin's structure and can detect drug-induced signaling pathways.
Area of Science:
- Biotechnology
- Tissue Engineering
- Dermatology
Background:
- Developing functional human skin models for drug screening remains a significant challenge.
- Existing models often lack the complexity and physiological relevance of native skin.
- High-throughput screening requires reproducible and physiologically accurate in vitro models.
Purpose of the Study:
- To develop a novel method for constructing microspheric skin organoids.
- To create a skin model suitable for high-throughput drug screening.
- To validate the model's ability to detect drug-induced signaling pathways.
Main Methods:
- Fabrication of core-shell structured microspheric skin organoids using spinning bioreactors.
- Culturing human keratinocytes (epidermis) and human dermal fibroblasts with collagen (dermis).
- Incorporation of a luciferase reporter system for Wnt pathway activation detection.
Main Results:
- Successfully developed uniform microspheric skin organoids mimicking human skin's bilayered structure.
- Demonstrated epidermal growth and differentiation, forming a mature barrier.
- Identified Minoxidil as an inducer of the epidermal Wnt/beta-catenin pathway signaling.
Conclusions:
- A novel and efficient method for preparing microspheric skin organoids has been established.
- These organoids show significant potential for high-throughput drug testing and screening applications.
- The model provides a valuable platform for studying skin biology and drug responses.
