This study found that extracts from the fungus YL161, Agaricus blazei, and the bark of Camptotheca cuminata promoted dermal papilla cell growth more effectively than pentadecanoic acid, suggesting potential for stimulating hair growth.

In this study on fine-wool sheep, researchers found that overexpressing the TGFBR1 gene decreased proliferation of dermal papilla cells by influencing multiple signaling pathways, suggesting TGFBR1 as a negative regulator in hair follicle development.

This study found that overexpressing FGF22 in dermal papilla cells enhanced hair follicle stem cell proliferation and viability, while its knockout reduced these attributes, indicating its role in hair follicle regeneration.

This study found that Ang1 improved survival and proliferation in human follicle dermal papilla cells under DHT-induced stress, suggesting potential as a therapeutic candidate for androgenetic alopecia.

In this case report, researchers detailed a giant proliferating pilomatrixoma in a 36-year-old woman, emphasizing the importance of complete excision to prevent recurrence or potential malignant transformation, distinguishing it from malignancies like angiosarcoma or melanoma.

This study found that downregulating miR-30a-5p levels inhibits apoptosis and promotes proliferation in hair follicle stem cells, which is associated with the activation of the Wnt/β-catenin signaling pathway.

This case study reports a near-complete response of a proliferating trichilemmal tumor to neoadjuvant radiotherapy in a 79-year-old woman, highlighting radiotherapy's role in managing this condition when patients are unsuitable for surgery.

This study suggests that the transcription factors SP1 and KROX20 regulate CUX1 gene's effect on the proliferation of ovine dermal papilla cells in vitro.

This study found that N,N-dimethylglycine sodium salt promoted proliferation and migration of cultured human epidermal keratinocytes and had anti-inflammatory and antioxidant effects in vitro.

This case report described a facial hairline tumor initially diagnosed as a sebaceous cyst but ultimately confirmed as a rare Proliferating Pilar Tumor with focal malignancies upon histopathological examination.

LED light helps human hair root cells grow and move by activating certain cell pathways.

This study found that hair follicle stem cells can proliferate and differentiate into keratinocytes on chitosan skin-engineered templates, suggesting potential applications in regenerative medicine.

This report presents the first known case of a proliferating hybrid cyst containing both epidermoid and trichilemmal components on the scrotum of a 44-year-old man.

This report describes an unusual case of proliferating trichilemmal cyst with trichoepitheliomatous change in a young woman, differing from its typical presentation in elderly women.

This study found that topical application of 17 alpha-propylmesterolone significantly increased proliferative activity in hair matrix cells in men with androgenetic alopecia.

This study found that small proline-rich proteins modify the biomechanical properties of cornified cell envelopes in rodent forestomachs, potentially affecting the tissue's ability to withstand mechanical stress.

Minoxidil slows fibroblast growth and collagen production, potentially treating keloids, hypertrophic scars, and connective tissue disorders.

This study found that the circadian clock in mouse skin regulates cell proliferation and affects sensitivity to UVB-induced DNA damage, with potential implications for understanding human skin cancer risk.

In this mouse study, researchers found that dermal Wnt signaling/β-catenin activity is essential for fibroblast proliferation and initiating hair follicle formation by interacting with epidermal Wnt ligands.

This study demonstrated that stress inhibited hair growth in mice, likely through substance P-dependent activation of immune cells, highlighting a brain-hair follicle connection.

Caspase-3 helps control cell growth and organ size by activating YAP.

This study discovered that a network controlled by the gene p63 is crucial for keratinocyte differentiation and is linked to MYC through cell adhesion-related pathways.

This study found that caffeine enhanced hair growth and keratinocyte proliferation in human hair follicles, with female follicles showing greater sensitivity than male ones.

This study identified altered expression of MMP-19 in the skin's epidermal layers during diseases like psoriasis and eczema, implying a role in disease processes.

Growth factors can either promote or inhibit hair follicle cell growth and collagen breakdown.

This study found that IGF-1 injections increased hair follicle number and growth phase duration in wild-type mice, suggesting potential for baldness treatment.

EGFR signaling is essential for ear cell regeneration in both birds and mammals.

This study found that ablating centrosomes in developing epidermis alters keratinocyte division without majorly affecting differentiation, suggesting early epidermal development is driven by high proliferation and cell delamination.

This study found that 1,25-dihydroxyvitamin D3/VDR inhibits β-catenin's role in keratinocyte proliferation but enhances its role in hair follicle differentiation.

This study found that LED light irradiation induced proliferation and migration of human outer root sheath cells, potentially through the stimulation of the Wnt/β-catenin and ERK signaling pathways.
