This review outlines the current state and future prospects of using layer-by-layer self-assembly for cell encapsulation in biomedical applications, such as cell-based biosensors, transplantation, and tissue engineering, while also discussing its limitations and potential advancements.

This review discusses the range of cutaneous immune-related adverse events induced by immune checkpoint inhibitors and the proposed mechanisms underlying these skin reactions, but reports no new clinical results.

This review highlights recent advancements in understanding and treating alopecia, emphasizing genetic and immune factors involved in different forms, and discusses emerging therapies such as gene-editing and exosome-based treatments, though achieving complete hair regrowth remains a challenge.

This study concluded that bone morphogenetic proteins are crucial for hair follicle stem cell differentiation and that their downregulation by androgens may contribute to the development of androgenetic alopecia.

This study suggests that early-stage dermal papilla cell-derived exosomes may enhance adipose stem cells' hair inductive abilities through specific miRNAs.

In this study, researchers used a new method with platelet-rich plasma-loaded microcarriers to enhance dermal papilla cell activity and hair follicle regeneration, achieving significant hair and vessel growth in a mouse model compared to control groups.

This review discusses the biology and signaling mechanisms of dermal papilla cells in hair follicle growth and reports no new clinical results; the authors emphasize the importance of optimizing culture conditions for hair restoration.

This study found that exosomal miR-181a-5p promotes hair follicle growth and development in vitro by activating the Wnt/β-catenin signaling pathway and suppressing hair follicle stem cell apoptosis.

This study found that stimulating dermal papilla cells with specific adipo-osteogenic factors and growth factors helped maintain their viability and restored their hair-forming activity in vitro.

In this study, researchers used a chemical cocktail and hydrogel microspheres to successfully guide fibroblasts into dermal papilla cells, promoting wound healing and in situ hair follicle regeneration while reducing scar formation, in both in vitro and in vivo experiments.

This study found that early passage dermal papilla cell-derived extracellular vesicles, combined with specialized medium, helped adipose-derived stem cells develop dermal papilla-like properties.

This study showed that treating mouse fibroblasts with TTNPB can efficiently convert them into dermal-papilla-cell-like cells with strong hair-inducing capacity, suggesting potential for hair follicle regeneration therapies.

This study found that dermal papilla cell-derived exosomes promote hair follicle regeneration during wound healing by enhancing fibroblast activity and activating the Wnt/β-catenin signaling pathway in mice.

This study found that the water extract of Cacumen Platycladi promotes hair growth and follicle development in mice, possibly by influencing dermal papilla cells through the Akt/GSK3β/β-Catenin signaling pathway.

This study suggests that linoleic acid from Malva verticillata seed extracts may promote hair growth and combat androgenic alopecia by activating Wnt/β-catenin signaling and stimulating dermal papilla cell proliferation in vitro.

This study analyzed 57 medicinal and cosmetic preparations available in Poland for treating alopecia, finding that finasteride is the most common active ingredient, with many products being in tablet or shampoo form and categorized as prescription drugs and cosmetics.

This study demonstrated that exposing hair follicle organ cultures to extremely low-frequency electromagnetic fields at 10 G intensity for 60 minutes promoted hair growth, suggesting its potential as a treatment for hair loss.

This study found that tdDPC-EVs significantly improved wound healing by enhancing angiogenesis through the KLF4/VEGFA axis, offering advantages over traditional DPC-EVs.

This chapter reviews genetic defects in female sexual differentiation, focusing on 46,XX disorders of sex development and the impact of genetic factors and sex steroids on development, but reports no new clinical findings.

Adipose-derived stem cells can be transformed into hair-forming cells using specific extracellular vesicles, offering potential for hair regeneration therapies.

This study found that transplanting trichogenous dermal cells significantly enhanced the restoration of in vivo-damaged hair follicles in a nude rat model, with a combination of dermal papilla and sheath cells proving more effective than either cell type alone.

In this study, VD(3) pretreatment increased hair follicle formation in a rat model by promoting dermal papilla cell differentiation, suggesting potential for hair regeneration therapy.

This study found that women with PCOS displayed significantly higher activity of 5alpha-reductase, suggesting an additional role for liver and peripheral tissues in their androgen excess.

This study found that lncRNA-599547 positively regulates the expression of the Wnt10b gene by interacting with miR-15b-5p, enhancing the inductive property of dermal papilla cells in cashmere goats.

In this study, researchers used yaks as a natural model to investigate hair growth mechanisms, overcoming previous limitations by establishing in vitro models of hair follicle-associated cells and optimizing methods for cell culture and differentiation.

This study found that women with PCOS have higher activity of the enzyme 5alpha-reductase, which may contribute to their elevated androgen levels.

This study found that Janus Kinase inhibitors, tofacitinib and baricitinib, showed effectiveness and safety in treating severe alopecia areata in a real-world setting, with optimal tolerability noted in younger individuals.

This study suggests that androstendione and DHEA are useful indicators for diagnosing hyperandrogenemia in hirsute women, while DHEAS was not found to be helpful.
