In this study, tubular 3D bioprinted structures made from sodium alginate and gelatin, containing NIH/3T3 fibroblast cells, demonstrated the ability for cell growth and network formation over 6 weeks, although structural tensile strength decreased with cell growth and polymer degradation.

In this study, extracellular vesicles from Saccharomyces cerevisiae demonstrated multifunctional bioactivity, enhancing cell proliferation and migration, reducing inflammation, and promoting collagen gene expression in hair follicle–related cells.

In this study, QR 678 and QR 678 Neo formulations containing growth factors and peptides were found to be safe in vitro and promoted hair growth in vivo in an animal model, suggesting their potential as treatments for alopecia, including secondary alopecia post-chemotherapy.

This case study describes a rare cutaneous follicular hybrid cyst intimately associated with syringocystadenoma papilliferum, proposing a potential relationship with the infrainfundibulum based on keratin expression.

This study found that hot water extract of Hydrangea serrata leaf and hydrangenol promoted hair growth by enhancing 5α-reductase inhibitory activity, stimulating dermal papilla cell growth, and exhibiting anti-inflammatory and anti-androgenic effects in cell cultures, mice, and human skin organoid models.

This review reports that Dang Gui (Radix Angelica sinensis) possesses bidirectional immunoregulatory effects, enhancing immune cell proliferation and function, and may benefit immune-related diseases such as cancer and anemia. It also evaluates regulatory and safety aspects, aiming to guide future research and clinical use.

This study observed that SY red pericarp rice extract promotes hair growth, inhibits 5α-reductase, and enhances hair regeneration in mice, with the extract being safe from cytotoxicity and irritation, indicating its potential as a natural hair growth promoter.

This article discusses the role of regulatory T cells in alopecia areata, where their deficiency in hair follicles may lead to impaired local immunity and suggests potential therapies like CAR-T reg cells and low-dose IL-2 to alleviate autoimmunity and promote hair regeneration in affected individuals.

This paper highlights the growing interest in exosomes for their therapeutic and diagnostic potential in cosmetic dermatology, noting their roles in skin rejuvenation, postprocedural care, and antiaging treatments.

This study found that dermal papilla cells may play a critical role in hair follicle development and cycling by promoting epidermal proliferation and potentially mediating systemic factors that influence follicle behavior.

This study extended a skin diffusion model to include a porous pathway, effectively explaining the permeability of both polar and lipophilic solutes through the stratum corneum.

This study found that overexpression of parathyroid hormone-related peptide in transgenic mice skin disrupted normal hair follicle development, suggesting a role for the peptide in the early stages of follicle formation.

This article discusses the potential of copper tripeptide (GHK-Cu) to support collagen synthesis and antioxidant activity in the context of androgenetic alopecia but reports no clinical results.

This study found that inhibiting NF-κB Essential Modulator (NEMO) in senescent murine dermal fibroblasts successfully reduced key factors associated with the senescence associated secretory phenotype (SASP), highlighting its potential as a therapeutic target for aging-related diseases.

This study found that TGF-β2 may enhance collagen expression and spheroid formation in human dermal papilla cells, which could improve their hair inductivity and maintenance.
