This study found that in neonatal mice, the absence of the NG2 proteoglycan leads to reduced epidermal thickness and delayed subcutis thickening due to impaired proliferation and adipocyte deficiencies.

This review discusses current concepts on the role of retinoids in keratinization and does not report new clinical results; the authors emphasize the complexity of retinoid effects on skin.

This study found that Blimp1+ cells from mice can generate sebaceous gland organoids in vitro, which mimic natural gland traits and may aid in studying acne vulgaris.

This review examines microneedle patches for drug delivery, detailing their designs, materials, manufacturing methods, and potential advantages, but reports no new clinical results.

This study found that adding keratin to a collagen hydrogel improved keratinocyte differentiation compared to a pure collagen hydrogel, particularly when calcium was also present in the media.

This review highlights the potential of microneedles as a pediatric-friendly method for delivering proteins, vaccines, and diagnostics transdermally, noting their ability to penetrate the skin's barrier and suggesting future applications in other parts of the body.

This article reviews the clinical challenges in diagnosing tinea capitis due to its varying symptoms and reports no new clinical findings, emphasizing the need for careful differential diagnosis.

Mutations in keratin genes may link hair disorders to dental decay.

This article reviews the role of stem cells and cytokines in hair growth and discusses existing and potential treatments, but it presents no new clinical data.

This study suggests that mouse lineage specification during pre-implantation development involves distinct timing and mechanisms for trophectoderm and inner cell mass differentiation, challenging existing models.

In this study, researchers developed a multilayered gel bead culture model using a microgel-spotting device, successfully mimicking the early development of skin appendages and supporting in vitro hair follicle regeneration with structures resembling native hair follicles.

This study found that basal cell carcinoma exhibits patterns of hair follicle differentiation but is stuck in telogen arrest, which can be rescued by adding noggin and TGF-β2 in vitro.

This study demonstrated that phosphatidylcholine liposomes can deliver calcein and melanin into hair follicles and shafts in mice without significant penetration into the dermis, epidermis, or bloodstream.

This study found that poly(adenosine diphosphate-ribose) synthesis in human skin varies by cell type and condition, with distinct patterns in psoriatic, cancerous, and normal tissues.

This review discusses the role of phospholipases in skin and hair health, suggesting that understanding their molecular control could inform new treatments for related conditions, but it presents no new clinical results.

This study developed a bilayer bionic skin scaffold that mimics the skin's structure to resist microbial invasion and enhance wound healing, with in vivo animal studies showing improved collagen deposition, neovascularization, and hair follicle formation.

This study identified significant metabolic differences between volar and non-volar skin in mice, revealing distinct amino acid, sugar, and nucleotide metabolism patterns associated with skin type differentiation.

This review discusses factors and disorders affecting healthy hair growth and loss but reports no new clinical results.

This study found that the desmosomal protein desmoplakin is crucial for proper epidermal morphogenesis and radial intercalation in developing Xenopus embryos, affecting keratin organization and ectodermal structures.

This study found that K15 is a useful marker for investigating the role of stem cells in canine hair follicle tumours, while nestin is not optimal.

This study found that the distribution of carbohydrates and proteins in porcine hair follicles and sebaceous glands showed minor differences compared to humans.

This study observed that PAD type III and trichohyalin are expressed earlier than their deiminated form during the first and second hair cycles in rat hair follicles, indicating a potential additional factor is involved in triggering deimination.

This study suggests that using nanostructured lipid carriers may improve the targeting of 17-α-estradiol in treating alopecia by improving skin penetration and stability.

This study found that repeated cycles of wetting and blow-drying hair fibers can cause cracks in the hair cuticles, particularly among individuals who frequently blow-dry their hair.

This study found that tight junctions extend to the most superficial layer of the stratum granulosum in human skin, challenging previous claims of their limited presence in the epidermis.

This report presents a case where female pattern hair loss might be linked to tamoxifen use, with increased androgen receptor expression observed in the affected scalp area.

This study found that using a ruby laser for hair removal resulted in a significant average reduction of 56.4% in hair density among participants dissatisfied with other methods.

This study found that human outer root sheath cells express VEGF receptor-2, and exogenous VEGF165 significantly stimulates their proliferation through activation of the ERK signaling pathway.

This study concluded that low-level fluence 810 nm diode laser therapy was generally well tolerated, safe, and effective for long-term hair reduction in a small sample of patients with various skin types.

This review discusses the factors affecting laser hair removal results and adverse events, emphasizing the need for more research to determine optimal treatment parameters; it reports no new clinical findings.
