This review discusses changes in keratin structure or gene expression that result in various skin disorders and reports no new clinical findings.

This study found that CRABP1, Nestin, and Ephrin B2 are expressed in both the tumor stroma and invasive front of skin adnexal tumors and basal cell carcinomas.

This study found that while 3D spheroid culture preserved sweat gland cell-specific markers better than 2D culture, their growth and structural organization were suboptimal, highlighting the need for improved culture systems.

This study found that protein hydrolysates from mealworms, especially those derived using flavourzyme, significantly enhance adipogenic differentiation in 3T3-L1 preadipocytes, suggesting their potential as sustainable ingredients for glycemic control, skin health, and tissue regeneration products.

In this study, researchers found that reducing FGF20 expression in dermal papilla cells of fine-wool sheep impedes the growth and differentiation of hair follicle stem cells, providing insights into wool trait improvement and regenerative medicine applications.

This review discusses current airway regeneration research efforts and reports no new experimental results, highlighting the need for clinical interventions to enhance airway repair.

In this study, researchers found that treating dermal papilla cells with synovial fluid and laser photobiomodulation increases the expression of chondrocyte marker genes, indicating potential promotion of chondrogenic differentiation.

This study reports for the first time on the expression patterns of Id2 and Id3 proteins in developing hair follicles, suggesting a significant role for these proteins in hair follicle development and epithelial-mesenchymal interactions.

This study found that in Hutchinson–Gilford progeria syndrome, iPSCs committed to the keratinocyte lineage faster than normal cells, with LEF1 expression reduced and a partial rescue of the phenotype achieved through adenine base editing.

In this study, subthermal RF-CRET currents were found to alter key molecular mechanisms in dermal papilla cells, promoting proliferation and survival while enhancing markers associated with hair growth and maintenance, suggesting potential benefits for hair regeneration.

This study found that keratin 15 expression is downregulated in hyperproliferative conditions like psoriasis and hypertrophic scars, suggesting it is not compatible with keratinocyte activation.

This study found that differentiated cells of the corneal epithelium can be converted to hair and interfollicular epidermis through a multistep process involving dermal developmental signals.

This study suggests that human outer root sheath cells are suitable for skin replacement, as they can form a stratified epithelium similar to normal epidermis in organotypic cultures.

This study found that the synthetic retinoid EC23 effectively induces keratinocyte hyperproliferation and enhances hair growth in mice, showing more potency than all-trans retinoic acid.

This study found that sulfur mustard affects hair follicles and sebaceous glands in the skin by causing cellular damage, inflammation, and disrupting wound healing processes in hairless mice.

In this study, researchers used transcriptomics and modeling to uncover previously unknown cell populations and marker genes in developing hair follicles, providing insights into early cell fate establishment and offering tools for further research on skin appendages.

Delta1 is crucial for controlling skin cell growth and preventing tumors in mice.

This study found that Sox9 was variably expressed in most canine skin neoplasms, particularly in those originating from the hair follicle's bulge region, suggesting its potential as a stem cell marker.

This study identified specific markers that can distinguish between stem cells in different regions of human scalp hair follicles, offering potential strategies for cell sorting and purification based on these markers.

This study found that YAP1 localization and expression patterns in human skin xenografts resembled pathological conditions, suggesting that YAP1 may be a potential target for treating skin pathologies.

This study reported that ELL is crucial for maintaining the proliferative capacity of the basal layer in human epidermal keratinocytes by stabilizing RNA polymerase II at the transcription start site.

This review reports that transcriptional and epigenetic mechanisms in epithelial stem cells guide their fate in the epidermis and hair follicles, crucial for skin homeostasis, but disruptions can lead to disease.

In this study, hair follicle-derived mesenchymal stromal cells showed potential for immunomodulation, with equivalent or superior responses compared to those from adipose tissue, suggesting a promising alternative cell source.

This study observed that post-surgical use of chlorhexidine digluconate mouth rinse in patients may induce a fibrotic transformation in gingival tissue, promoting a scar-like wound healing response.

Krox20 is crucial for hair growth and maintaining skin stem cells.

This review discusses the role and interactions of the calcium-binding protein S100A6 in cellular processes and its association with various diseases, highlighting the need for further research to fully understand its biological impact.

The researchers concluded that their new reconstructed human epidermis model from plucked hair follicle-derived keratinocytes offers a safer and simpler alternative to traditional skin-derived models for studying epidermal function.

A 4kb fragment of the desmocollin 3 promoter targets gene expression to specific skin and hair follicle areas.

This study concluded that the inner root sheath inhibits the expression of certain differentiation markers in hair bulbs, with calcium-induced changes paralleling those seen in hair follicle mid-segments.

This study found that CD34- melanocyte stem cells regenerated pigmentation more efficiently, while CD34+ cells showed potential for neuron myelination, suggesting different therapeutic applications for each population.
