November 2023 in “Journal of Functional Biomaterials” This study investigated nanocomposite scaffolds made from alginate, chitosan, and graphene oxide to promote the proliferation of spermatogonial stem cells, finding the ALGCS/GO30 scaffold to be particularly effective due to increased proliferation markers and PLZF protein expression compared to controls.
32 citations
,
July 2003 in “Histochemistry and Cell Biology” April 2012 in “Development” This study found that Rac1 activity in specific skin compartments is sufficient for hair formation, but results in hair with altered structure and pigmentation compared to normal.

June 2019 in “Proceedings of the National Academy of Sciences” This study introduces a method for long-term expansion of adult mouse epidermal stem cells in vitro using an organoid culture system that maintains the basal-apical organization.
December 2017 in “bioRxiv (Cold Spring Harbor Laboratory)” This study found that Endoglin is crucial for proper hair follicle cycling and the activation of hair follicle stem cell niches, based on its role in the feedback crosstalk between Wnt/β-catenin and Bmp/Smad signals.
June 2026 in “Nano Research” In this study, researchers developed a novel 3D bio-printed skin scaffold using exosomes from liver cells, which enhanced wound healing by promoting cell growth, angiogenesis, and reducing inflammation in large skin injuries, suggesting potential applications in treating chronic skin conditions.

2 citations
,
January 2001 in “Biomedical Research” This study found that peptidylarginine deiminase type III and trichohyalin are coincidentally expressed in the infant rat hair follicle, but trichohyalin deimination occurs after their expression during development.
January 2026 in “British Journal of Dermatology” This study found that neither caffeine nor N,N-dimethylglycine treatments were toxic to balding or nonbalding dermal papilla cells and could stimulate calcium influx, indicating treatment responsiveness.
