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.

This chapter reviews the hair follicle's role in drug and chemical penetration through the skin but does not present new experimental findings.

This article provides an overview of hair density, hair diameter, and the prevalence of female pattern hair loss but reports no new clinical findings.

In this study, researchers evaluated emulsions made with natural plant extracts and oils on guinea pigs, finding that a specific hydrophilic/lipophilic balance and globule size led to a stable emulsion and stimulated hair growth.

This study found that the Arabidopsis thaliana protein Formin 2 localizes to plasmodesmata and is crucial for regulating their permeability by anchoring actin filaments, which affects virus susceptibility.

This study suggests that Sonic hedgehog from hair follicles may support the proliferation of dentate neural stem cells in mice through transport by platelets during the perinatal period.

This brief article is a response from the authors about hair density, hair diameter, and female pattern hair loss, and it reports no new clinical findings.

FPHL affects hair density and diameter, causing visible hair loss in older women.

This study found that nanoemulsions of different sizes vary in their ability to penetrate skin layers, with smaller sizes aiding transdermal delivery and potential applications in transcutaneous immunization.

This study observed that primary hair follicles in Liaoning Cashmere goats had broader hair bulb widths compared to secondary follicles, with the difference diminishing during the anagen phase of hair follicle development.

This study found that the transcription factor Lhx2 regulates Sonic Hedgehog signaling in mouse retinal progenitor cells, mainly by controlling the expression of co-receptors essential for effective pathway activation during early retinal neurogenesis.

This study identified genetic regions evolving at different rates in hairless mammals, suggesting that specific genomic changes may contribute to the evolution of hairlessness across various species.

This study found that the Arabidopsis cation chloride cotransporter (CCC1) is crucial for regulating pH and processes in the trans-Golgi-network/early endosome, impacting plant growth and stress responses.

This study found that GNAQQ209L expression in mouse melanocytes led to reduced survival in the interfollicular epidermis due to paracrine signaling, while GNAQQ209L boosted survival in a different microenvironment.

This study found that chronic UVR exposure in mice and humans leads to a permanent loss of papillary fibroblasts in the upper dermis, which is associated with changes in the extracellular matrix.

This study using Mendelian randomization suggests lifelong increased free testosterone in males may have beneficial effects such as increased bone mineral density and decreased body fat, but also increased risks of prostate cancer and hypertension.

In this study, researchers observed that oncogenic HrasG12V in single murine epidermal cells leads to an initial increase in progenitor cell renewal, but ultimately results in balanced cell fate choices that limit clone growth.

This study found that neutrophils are crucial for initiating chronic itch in atopic dermatitis and suggest that targeting neutrophils may help alleviate symptoms in this condition.

This study found that activating Hedgehog signaling in both epithelial and stromal cells can induce new hair follicles in adult mice, but this also leads to tumor formation.

This study identifies Activin A and follistatin as key regulators of hair cell differentiation in the mouse auditory sensory epithelium, influencing the timing and pattern of hair cell development.

In this study, upper-bulge epidermal stem cells in mouse hair follicles were shown to play a role in forming tactile sensory units by creating an extracellular matrix that supports nerve interactions.

This study found that fibroblast growth factor 20 (Fgf20) orchestrates the movement and behavior of dermal fibroblasts, directing their formation into dermal condensates during hair follicle development in mice.

This study found that type XVII collagen is crucial for regulating epidermal cells' proliferation in mice and may be a promising target for anti-aging skin treatments.

The research found that while Dnmt3a and Dnmt3b are not necessary for skin homeostasis in mice, the loss of Dnmt3a increases squamous tumor formation from carcinogens, and combined deletion of both results in more aggressive and metastatic tumors.

This study found that Smad4 is crucial for satellite cell amplification during skeletal muscle regeneration, with aged cells exhibiting less Smad4 and reduced regenerative capability in mice.

This study suggests that the ANE syndrome mutation in yeast Nop4, analogous to human RBM28, disrupts protein folding and protein-protein interactions, contributing to ribosomal dysfunction.

This study highlights promising methods for converting food waste into valuable resources such as biogas, bioethanol, biodiesel, fertilizers, and antioxidants through processes like fermentation and anaerobic digestion, emphasizing the need for robust large-scale technologies to optimize this "waste to value" transformation.

In this clinical case report, a 10-year-old girl developed acute hair matting three weeks after scalp trauma and frequent povidone-iodine use, suggesting that scalp injuries and antiseptic overuse can be risk factors for this condition, especially when hair care is poor.

This study found that MPZL3 knockout mice showed reduced dermal white adipose tissue and increased sebocyte proliferation, suggesting a regulatory role for MPZL3 in lipid metabolism balance between adipocytes and sebocytes.

This study found that treatment modalities and patch size influence hair regrowth patterns in alopecia areata patches.
