September 2025 in “bioRxiv (Cold Spring Harbor Laboratory)” This study found that human dermal papilla cells are surrounded by a basement membrane-like extracellular matrix, which maintains their aggregated structure without strong cell‒cell contacts.
March 2026 in “Mendeley Data” This study found that human dermal papilla cells are embedded in a basement membrane-like extracellular matrix, which is essential for their aggregation and function, as supported by evidence that Matrigel enhances dermal papilla cohesion and gene expression compared to collagen I, which promotes cell dispersion.

September 2019 in “Journal of Investigative Dermatology” This study found that combining human dermal papilla fibroblasts with hair matrix cells formed organoids capable of limited hair follicle development in ex vivo skin, but not fully formed hair follicles.
In this study, Fgf20 was found to trigger movement and morphogenesis in dermal fibroblasts, facilitating dermal condensate formation essential for hair follicle development.
