Application of 3D Scaffold-Free Dermal Spheroids to Investigate Retinol and Retinol Alternatives Mechanism of Action on Extracellular Matrix

In this study, researchers developed a new SFL-3D system to produce extracellular vesicles from rejuvenated dermal papilla cell spheroids, which demonstrated significant antifibrotic effects in reducing hypertrophic scarring, highlighting their potential for precision-targeted scar management.

This study developed an in vitro 3D organoid model using dermal papilla spheroids and found that it enhances growth factor expression and extracellular matrix production, which could aid drug screening for hair regeneration.

This study introduces a spherical skin model that effectively mimics key features of human skin, offering a scalable and rapid alternative for non-animal dermatological and cosmetic testing.

This study suggests that activating the hexosamine pathway may enhance skin homeostasis, potentially increasing hair follicle stem cells and modifying extracellular matrix components like hyaluronic acid in vitro.

This study found that using 3D Gel-C6S-HA scaffolds seeded with VEGF165-modified rat hair follicle stem cells enhanced angiogenesis and vascularization in tissue-engineered skin, improving wound healing.
