This study reports that the β-catenin inhibitor tegatrabetan reduced hair growth and hair follicle numbers in mice, suggesting its potential as a model for developing new hair growth materials.

This study found that Dab2 conditional knockout mice experienced delayed hair follicle cycles and reduced hair follicle stem cell activity, suggesting Dab2's crucial role in regulating stem cell activation and anti-aging process in hair follicles.

This study found that epidermal growth factor treatment in male mice delayed normal skin development, inhibiting hair growth and follicle development by maintaining birth-level cell proliferation and differentiation for several days.

Intermittent fasting slows hair growth by damaging hair follicle cells.

This study found that leachate from crownvetch seeds drastically inhibited the growth of shoots and roots in various plant species, despite the osmotic pressure being too low to account for these effects.

In this study, researchers found that girls aged 4-8 years with isolated premature thelarche had significantly advanced bone age, with obesity and elevated serum IGF-1 SDS and DHEAS SDS being key independent risk factors.

In this study, rice straw-derived smoke water enhanced root growth in rice plants by increasing root meristem size and cell proliferation, reducing superoxide accumulation under phosphorus deficiency, and altering internal phosphorus partitioning, although it suppressed root hair elongation, which affected phosphate uptake.

This study observed telogenic defluvium and dystrophic hair loss in patients with nutritional deficits, with reversible damage when diet improves and stress is alleviated.

STAT5 is crucial for hair growth in 3D cultured human dermal papilla cells.

This case report describes a 4-year-old girl with Rapunzel syndrome, presenting with severe anemia and a contained perforation, who underwent successful surgical removal of a large gastric trichobezoar.

A 19-year-old male with delayed puberty was successfully treated for a condition that prevents normal hormone production.

This study found that a lack of fat tissues in the hair root during the telogen phase might indicate hair loss, potentially providing a standard for identifying hair conditions and the impact of cytotoxic drugs.

In this study with mice, simultaneous inactivation of Smad4 and PTEN genes led to rapid development of invasive forestomach squamous cell carcinomas, mirroring human esophageal SCCs.

This study found that manipulating SIMK expression in alfalfa affects root hair growth, infection thread and nodule formation, and overall plant biomass, highlighting its potential biotechnological applications.

In a pilot study with 21 patients, the niostem device increased hair counts and density and enhanced testers’ self-perception of hair growth at 6 months without reported adverse effects, suggesting potential benefits for androgenetic alopecia.

This case report describes a 3-year-old girl with short hair since birth, showing normal hair density with many vellus and intermediate hairs, and no hair shaft abnormalities.

In this study, the deletion of Smad4 and PTEN genes in mice was associated with rapid and invasive squamous cell carcinoma formation in the forestomach, modeling human esophageal cancer progression.

This study suggests that patients with STSD show a different pattern in androgen activation compared to healthy controls, potentially due to increased 5α-reductase activity and absent prepubertal serum DHEA surge.

This study found that knocking down the gene SFRP1 in human hair follicles ex vivo prolonged the hair growth phase and increased keratinocyte proliferation, suggesting potential as a therapeutic target for maintaining hair growth in male pattern baldness, while DKK1 knockdown showed no effect.

This study found that young host mice rejuvenated aged hair follicles after transplantation, while aged host mice did not support hair growth from transplanted follicles.

In this study, the degradation of HHK scaffold particles was linked to the activation and proliferation of satellite cells, which may contribute to new muscle fiber formation.

This study found that transplanted hair follicle-associated pluripotent stem cells in mice differentiated into keratinocytes and stimulated hair growth by producing mature hair shafts.

This study found that epidermal growth factor decreased hair growth rate and altered hair characteristics in neonatal mice, with some effects persisting into subsequent hair generations.

This study provides evidence that root hairs significantly enhance phosphorus uptake in barley when phosphorus availability is limited in the root zone.

In this study, researchers found that proteins derived from stressed mesenchymal stem cells, stimulated using the root extract of Atalantia monophylla, successfully promoted hair growth and activated hair follicle stem cells in a mouse model of androgenetic alopecia through the Wnt and TGF-β pathways.

This study describes a 4-year-old boy who exhibits a rare, synchronized pattern of hair growth and shedding, unlike the typical asynchronous pattern seen in humans.

This study found that girls with isolated premature thelarche, confirmed by GnRH stimulation test, aged 4-8 years, may have significantly advanced bone age, with obesity and serum IGF-1 and DHEAS levels being key risk factors.

This case study reported that growth hormone therapy dramatically improved rickets symptoms and growth in three children with vitamin-D dependent rickets type 2 who had not responded to standard treatments.

This study identified a key Arabidopsis thaliana gene, TIP1, whose product is involved in S-acylation crucial for normal plant cell growth, particularly affecting root hair development.
