This review discusses the cyclical phases of hair follicle transformation and the various factors that regulate hair growth, reporting no new clinical results.

This study found that transplanted microencapsulated dermal papilla cells in rat footpads can regenerate hair follicles and sebaceous gland structures, suggesting a potential substitute for fresh dermal papillae cells.

This study found that a stochastic follicular automaton model replicates hair follicle cycle fluctuations, with deterministic simulations aligning with steady-state levels as follicle numbers increase.

This study found that the volume of a hair follicle's dermal papilla is strongly correlated with its size, primarily due to the number of cells it contains and the volume of extracellular matrix.

This study found that human dermal papilla cells are surrounded by a basement membrane-like extracellular matrix, which maintains their aggregated structure without strong cell‒cell contacts.

This article mentions that the slot correction technique by Dr. Patrick Frechet has been a valuable tool in the author's 100% hair restoration surgery practice but does not provide new clinical results.

This study observed that isoproterenol directs hair-follicle-associated pluripotent stem cells to differentiate into cardiac muscle cells in large numbers, forming tissue sheets of beating heart muscle cells in culture.

This case report describes a hybrid cyst in a Sprague-Dawley rat, showing both infundibular and matrical differentiation similar to different parts of normal hair follicles.

In this study, the researchers found that using a core-shell assembly of adipose-derived stem cells and dermal papilla cells reconstructed hair follicle cellular arrangements more effectively than mixed assemblies, enhancing hair formation in vivo.

Women with pituitary adenomas often have reproductive issues, like irregular periods and trouble getting pregnant, but not always breast milk production without pregnancy.

This study found that injury affects the behavior of hair follicle dermal stem cells, steering them towards recruitment into the dermal papilla, a shift influenced by the hair cycle stage.

This review discusses techniques for analyzing the cell cycle, highlighting emerging tools for measuring cell cycle speed at single-cell resolution in live animals, and reports no new results.

This study found that dermal papilla cells can induce hair follicle regeneration and maintain growth in vitro and in vivo, with higher ET-1 and SCF expression enhancing this ability.

This study discovered that key genes like KAP3-1 and KRTAPs are closely linked to the growth cycle of cashmere in Inner Mongolian goats, identifying March as the primary cycle's onset.

This research observed that dermal papilla cells have the potential to regenerate hair bulbs under preferred environmental conditions when associated with dermal sheath cells or exposed to specific growth factors.

This article details laboratory methods for isolating and culturing human dermal papilla cells but provides no new experimental results.

This study used single-cell and spatial transcriptomic profiling to identify specific molecular markers in human follicular dermal papilla cells, enhancing understanding of their role in hair follicle development.

In this study, researchers developed a custom-designed 3D-printed microscope stage insert for inverted confocal microscopes, enhancing the accessibility of long-term intravital imaging of live cell dynamics in live transgenic mice, particularly in the skin.

In this study, researchers developed non-invasive methods to monitor hair shaft, melanin, and collagen dynamics in C57BL/6 mice across different hair follicle cycle phases, supporting non-invasive research in hair loss treatment development.

This study found that dermal papilla cells cultured in vitro can promote hair follicle regeneration and maintain hair growth, with stronger ET-1 and SCF expression enhancing this regenerative ability.

This research observed that during the catagen phase, the inner root sheath of hair follicles becomes an early target, highlighting its potential role in maintaining hair follicle homeostasis.

This study found that cultured papilla cells can induce follicle formation and hair growth when combined with different epidermal and dermal cells, highlighting their powerful inductive properties and potential for dermatological applications.

This letter details 11 cases of scalp pseudocyst treated primarily with intralesional triamcinolone, resulting in complete hair regrowth in eight patients and self-resolution in some instances.

This study demonstrated that injecting reconstructed dermal papilla-like tissues in mice led to new hair growth, suggesting potential future applications in hair transplantation and baldness treatment.

This study observed that, in mouse ear epidermal stem cells, a cell-autonomous size control mechanism involving the RB pathway dictates S phase entry timing based on cell size, despite external environmental variations affecting growth rates.

This case report highlights the successful use of the Bardach modification of the curved tripod flap for repairing cicatricial pressure alopecia, offering a natural appearance and effective tension distribution in scalp reconstruction.

The study reports that Fgf18 and Tgf-β2 signaling pathways in hair follicle stem cells have opposing effects on the timing of hair cycle transitions, influencing the shift from telogen to anagen phases.

In this case report, the authors describe a rare cystic panfolliculoma in an 84-year-old man's right conchal bowl, noting its potential to mimic other tumors like basal cell carcinoma, which complicates diagnosis.

This study found that a 3D Matrigel culture technique for dermal papilla cell spheroids can enhance hair follicle inductivity and induce hair-like fiber differentiation in vitro, even with high-passage cells.
