This study found that downregulation of EGF and KGF signaling is necessary for hair follicle initiation in placodes, revealing a new role for KGF in hair follicle formation in mice.

Krt6a-Cre transgenic mice help study gene effects on hair follicle development and tumor suppression.

This study found that interfollicular injection of autologous CD34+ cell-containing PRP preparation improved hair count and thickness in patients with pattern hair loss, with better results than placental extract treatment.

This study suggests that chronic treatment with TPA in mouse skin selectively expands a keratinocyte subpopulation hyperinducible for ODC, which may be a key target for neoplastic transformation.

This study found that platelet-rich plasma significantly increased hair density in patients with androgenic alopecia after three months of treatment.

This study found that intradermal administration of adipose-derived stem cell–conditioned medium significantly increased hair density and dermal thickness, suggesting potential regenerative effects on both hair follicles and the interfollicular scalp in patients with alopecia.

This review examines the origins and mechanisms of tumor initiation in common skin cancers, but does not present new experimental findings; it emphasizes the need for further research on cancer stem cells.

In this study, 23 patients with androgenetic alopecia were treated with non-activated autologous platelet-rich plasma (A-PRP) administered through interfollicular injections, but the abstract provides no results of the treatment's effectiveness.

This study observed that hairless HRS/J mice were resistant to Bacillus anthracis infection at the skin's surface, suggesting resistance may be due to increased dermal neutrophils rather than non-functional hair follicles.

This study observed that among 120 patients recovering from COVID-19, severe diffuse hair loss typically began less than two months post-infection, with the majority of patients experiencing a severe degree of hair loss and positive hair pull tests, often alongside vitamin D deficiency.

This case report highlights an unusual trichoscopic appearance in alopecia areata due to dithranol staining, which may obscure typical patterns and reveal atypical vascular features in the interfollicular spaces.

In this study, researchers found that TSPyV T antigens can disrupt normal cell differentiation and proliferation in hair follicles and interfollicular epidermis, possibly contributing to trichodysplasia spinulosa pathology.

This study found that Schistosoma mansoni cercariae stimulate epidermal keratinocytes in mice, initiating pro-inflammatory responses and barrier repair mechanisms akin to those in wound healing.

Staphylococcus epidermidis affects hair growth and metabolism, suggesting it could help manage hair growth issues.

CD73 may regulate hair growth and could be targeted for hair growth treatments.

In this study, mouse skin exposed to cigarette smoke condensate exhibited increased epidermal thickness and ODC expression, with some changes persisting after exposure ended, suggesting potential for tumor promotion and measurement discrimination.

This correspondence reports that using cantharidin on warts can result in lymphangitis, and dermatologists should consider all potential complications of treatments.

This study found that the activity of CD73, an enzyme expressed in the hair follicle epithelium, may regulate human hair growth by modulating adenosine production.

This study found that nanocapsules formulated as a dispersion and applied with massage may enhance follicular uptake of clobetasol propionate while minimizing its skin penetration, offering a potential improvement over conventional treatments for scalp diseases.

This study found that kaempferol increased the proliferation potential of basal epidermal cells in three-dimensional skin models by enhancing integrin expression and altering cell morphology.

This study found that hair follicle and interfollicular epidermis stem cells contribute differently to skin regeneration, with their persistence influenced by factors like spatial constraints and competition moderated by Notch suppression.

This study reports that mesotherapy for androgenetic alopecia may paradoxically lead to hair loss and scarring, highlighting the need for improved regulation and monitoring of this treatment.

This study found that TPA was significantly more effective than mezerein in inducing dark basal keratinocytes in mouse skin, which may be important in early tumor promotion stages.

In this study, subcutaneous platelet-rich plasma injections improved hair density and histological markers of hair growth in hairless rats without causing local toxicity.

PRP injection therapy shows promise for treating hair loss, increasing hair count and thickness with minimal side effects.

This study found that α3β1-integrin is crucial for maintaining normal hair follicle morphology in mice, as its deficiency leads to severe abnormalities despite not affecting interfollicular epidermal differentiation.

This study shows that BMP2 and BMP7 play complex, necessary roles in feather development by regulating dermal condensation formation, with BMP7 acting early as a chemoattractant and BMP2 halting cell migration.

This study suggests that human dermal fibroblasts can be converted into dermal papilla cell-like cells using microencapsulation, which may facilitate hair follicle regeneration in mice without chemical or genetic reprogramming.

This study observed that alopecia areata can be induced and serially transferred in C3H/HeJ mice using skin grafts, providing a useful model for studying the disease in humans.

Finasteride helps induce ovulation in nonresponder PCOS women.
