A Novel Approach to Pattern Dermal Papilla Spheroids in Dermal–Epidermal Composites Using Non-Adherent Microwell Arrays

Bioengineering
Bioengineered dermal–epidermal composites (DECs) have demonstrated promise initiating skin regeneration and hair follicle neogenesis after injury. DECs in our work comprise a collagen matrix embedded with human dermal papilla cells (HDPCs) overlaid with ...

Vascular Endothelial Growth Factor Is an Autocrine Growth Factor for Hair Dermal Papilla Cells [PDF]

, 1996
The transition of the late anagen to the catagen phase is concomitant with the disappearance of perifollicular capillaries, and therefore cyclical hair growth might depend on the ability of the dermal papilla to synthesize and release soluble growth and ...

Nanoplastics: Methods, Exposure and Effects on Domestic, Farm and Wild Animals

Journal of Applied Toxicology, EarlyView.
ABSTRACT Nanoplastics (NPs) are synthetic polymer particles ranging in size from 1 nm to 1 μm that have been identified as a major concern for ecosystems and organisms due to their plethora of negative effects. The aim of this review is to provide a comprehensive overview of the knowledge relating to exposure and effects of NPs in domestic (i.e., farm ...

Hair Follicle Dermal Stem Cells Regenerate the Dermal Sheath, Repopulate the Dermal Papilla, and Modulate Hair Type [PDF]

, 2014
SummaryThe dermal papilla (DP) provide instructive signals required to activate epithelial progenitors and initiate hair follicle regeneration. DP cell numbers fluctuate over the hair cycle, and hair loss is associated with gradual depletion/atrophy of ...

Comparison of Continuous‐Time Random Walk and Fractional Order Calculus Diffusion Models for Preoperative Breast Lesion Characterization: Diagnosis, Biomarker Prediction and Molecular Subtyping

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Accurate preoperative characterization of breast lesions is important for individualized management. The conventional monoexponential (Mono) model has limited ability to capture the complex microstructure of lesions. Non‐Gaussian diffusion models, including continuous‐time random walk (CTRW) and fractional‐order calculus (FROC), may

Twenty‐four month clinical outcomes of modified coronally advanced tunnel technique with leukocyte‐ and platelet‐rich fibrin–functionalized porcine dermal matrix for single/multiple gingival recessions

Journal of Periodontology, EarlyView.
Abstract Background To report 24‐month clinical and 3D outcomes of single and multiple RT1 and RT2 gingival recessions treated with the modified coronally advanced tunnel (MCAT) technique and an L‐PRF‐functionalized porcine dermal matrix (PDM), as long‐term data on PDM in root coverage are scarce.

Reconstruction of human dermal papilla-like tissue in vitro

, 2009
Dermal papilla (DP) plays an important role in the development and growth of hair follicles through epithelial–mesenchymal interactions. In animal studies, removal of lower hair follicles, including dermal papilla, resulted in discontinued hair growth

Effect of Androgens on the Growth of Cultured Human Dermal Papilla Cells Derived from Beard and Scalp Hair Follicles [PDF]

, 1991
Androgens stimulate hair growth in some areas, e.g., beard, but may cause regression and baldness on the scalp. The mesenchyme-derived dermal papilla is believed to regulate many aspects of hair growth. It is probable that androgens exert their effect on

Characterization of hair follicle development in engineered skin substitutes.

PLoS ONE, 2013
Generation of skin appendages in engineered skin substitutes has been limited by lack of trichogenic potency in cultured postnatal cells. To investigate the feasibility and the limitation of hair regeneration, engineered skin substitutes were prepared ...

LC‐OCT Features in Vitiligo: A Preliminary Report

JEADV Clinical Practice, EarlyView.
ABSTRACT Background Vitiligo is a chronic depigmenting disorder characterized by the selective loss of melanocytes, leading to the progressive development of hypopigmented macules and patches. Line‐field confocal optical coherence tomography (LC‐OCT) is a novel imaging technique that combines the advantages of optical coherence tomography (OCT) and ...
