This study identified the presence of recognizable organelles, such as lysosomes and mitochondria, in both the keratinized fiber and the hardened inner root sheath of the Romney wool follicle.

This study found that acid and alkaline phosphatases serve different functions in Beagle dog skin, with ALP primarily involved in growth processes and ACP in phospholipid breakdown.

This study found that valproic acid promoted hair re-growth in C3H mice by activating the Wnt/β-catenin pathway, suggesting its potential as a treatment for alopecia.

This study found that Annurca apple polyphenolic extracts reprogram hair follicle metabolism in mice, enhancing mitochondrial activity and keratin production while inhibiting some metabolic pathways.

This study found that hair root sheaths can be accurately typed for erythrocyte acid phosphatase, adenylate kinase, and adenosine deaminase, consistent with blood typing results from the same donors.

This article reviews the molecular interactions involved in hair follicle cycling and highlights the role of dermal papilla cells, but it presents no new research findings.

This study found that L-ascorbic acid 2-phosphate could reduce DHT-induced DKK-1 expression in balding scalp cells, suggesting potential for treating androgen-driven hair loss.

In this study, l-Ascorbic acid 2-phosphate was found to stimulate hair follicle growth in vitro by promoting IGF-1 expression via the PI3K pathway.

This study reports that versican expression plays a crucial role in maintaining the anagen phase and hair inductive properties, as shown in a transgenic mouse model and hair growth assays.

This review discusses the roles of epithelial-mesenchymal interactions and dermal papilla in hair follicle growth and cycling, but it reports no new clinical results.

This study found that glutathione deficiency affects lateral root and root hair responses to indole butyric acid in plants, but not to indole acetic acid, indicating its role in auxin pathway regulation.

This study found that a bacterial endophyte from Zea nicaraguensis effectively targets and colonizes plant root hair cells, promoting growth and solubilizing insoluble phosphorus for nutrient uptake.

In this study, the gene SlPHL1 was identified as a transcription factor in tomatoes that enhances phosphate starvation responses by upregulating specific genes.

This review discusses the role of lysophosphatidic acid in skin physiology and pathology, highlighting its significance in processes like wound healing and hair follicle development, but reports no new clinical findings.

This study observed that piperonylic acid activated key signaling pathways in dermal papilla cells and increased hair growth markers, and a clinical trial showed users of a piperonylic acid formulation had more hair than those using a placebo, suggesting its potential for treating hair loss.

This study suggests that lithocholic acid may enhance hair regeneration in alopecia by activating vitamin D receptors in human dermal papilla cells.

In this study, researchers developed an environmentally friendly hair coating from casein proteins and tannic acid, enhancing the tensile strength of virgin Asian hair by approximately 21% compared to untreated hair, while maintaining elasticity.

This study identified ten compounds from Eclipta prostrata, with some displaying potent inhibitory effects against α-glucosidase and acetylcholinesterase enzymes.

This study observed that while valproic acid treatment in children led to occasional mild clinical and laboratory side effects, no correlation with drug plasma levels was found.

This study found that Wnt1a overexpression from bone marrow mesenchymal stem cells enhanced hair follicle regeneration in mice by promoting the dermal papilla's role in hair cycling and gene expression recovery.

This study found that nanoemulsions incorporating skin penetration enhancers significantly increased the permeation of minoxidil through human skin compared to aqueous control solutions.

This study found that the cocrystal of mycophenolic acid with isonicotinamide significantly improved solubility and dissolution rate, while two other cocrystals showed decreased performance in these areas.

In this study, EPC-K, a compound with antioxidant and moisturizing effects, was found to decompose significantly under certain conditions, impacting its stability in quasi drug hair-growing products.

This study describes trichilemmal keratinization as a distinct process of hair follicle keratinization that occurs in specific areas of the outer root sheath, illustrated using electron microscopy on dog hair.

This study explored the potential of using isoenzyme detection after electrophoresis to characterize human hair, though no new clinical results are reported.

This study found that specific enzymes could be detected in fresh hair sheath cells, with most remaining detectable in older cells, except for Adenylate kinase and Esterase D.

This study examined the age-related changes in the dermal structure of goat skin, providing baseline data on its histomorphology, histochemistry, and histoenzymology.

This study suggests that D-panthenol may promote hair growth by enhancing cell viability, suppressing apoptosis markers, and elongating the anagen phase in human hair follicle cells.

This review discusses the pathophysiologic role of lysophosphatidic acid in the skin and reports no clinical results, suggesting pharmacological inhibition as a potential treatment for various skin disorders.
