270-300 / 1000+ resultsresearch Seborrheic karatosis, a tumor of the infundibular and isthmus of hair follicles: Identification of hair sheath keratins and histopathological features suggesting hair follicle origin.
Seborrheic keratosis likely originates from the upper regions of hair follicles.
research Alopecia areata with lymphocytic mural folliculitis affecting the isthmus in a thoroughbred mare
The horse had a rare type of hair loss caused by immune cells attacking hair follicles.
research Epithelial stem cells and implications for wound repair
Different types of stem cells in hair follicles play unique roles in wound healing and hair growth, with some stem cells not originating from existing hair follicles but from non-hair follicle cells. WNT signaling and the Lhx2 factor are key in creating new hair follicles.
research Developmental timing of hair follicle and dorsal skin innervation in mice
Nerve growth in mouse skin and hair follicles happens in stages and is closely linked to hair development.
research Morphometric Analysis of the Human Scalp Hair Follicle: Practical Implications for the Hair Transplant Surgeon and Hair Regeneration Studies
The research provides specific measurements for hair follicles that can improve hair transplant and regeneration techniques.
research The Transverse Anatomy of Androgenic Alopecia
The study found that horizontal sections of scalp biopsies are better for analyzing hair loss, showing fewer hairs and more fine hairs in balding areas.
research Localization of Merkel cells at hairless and hairy human skin sites using keratin 18
Merkel cells are more densely found in hairless skin areas like palms and soles.
research The Arrector Pili Muscle and the Follicular Unit of the Scalp: A Microscopic Anatomy Study
The study found that hair follicles are above muscle connections in the scalp, which may help protect stem cell areas.
research Evaluation of perifollicular inflammation of donor area during hair transplantation in androgenetic alopecia and its comparison with controls
Inflammation around hair follicles may worsen hair loss; evaluating and treating it can improve transplant results.
research Matriptase Expression and Zymogen Activation in Human Pilosebaceous Unit
Matriptase is highly active in hair follicles and sebaceous glands, especially during hair growth phases.
research Fibrosing Alopecia in a Pattern Distribution Localized on Alopecia Androgenetica Areas and Unaffected Scalp
A man with hair loss developed a condition causing scarring and inflammation in both bald and non-bald areas of his scalp.
research Expression pattern of human hair keratin basic 1 (hHbl) in hair follicle and pilomatricoma
hHbl gene is active in hair shaft cells and some pilomatricomas.
research [An immunohistochemical study on cell differentiation in the outer root sheath of the normal human anagen hair follicles with antikeratin monoclonal antibodies].
Keratinocytes in hair follicles differentiate similarly to skin cells, with specific patterns in different regions.
research Adipose Infiltration of the Dermis, Involving the Arrector Pili Muscle, and Dermal Displacement of Eccrine Sweat Coils: New Histologic Observations in Frontal Fibrosing Alopecia
The conclusion is that fat tissue in the skin is a new finding in Frontal fibrosing alopecia and may contribute to hair follicle and muscle degeneration.
research The Arrector Pili Muscle and the Follicular Unit of the Scalp
Each group of hair follicles on the scalp shares one muscle that helps control hair movement.
research Lichen planus pigmentosus (LPP) and lichen planus pigmentosus: 35 cases in Armenia, Colombia
Lichen planus pigmentosus and fibrosing frontal alopecia in Colombia are likely different stages of the same disease.
research 1388 Clinicopathological characteristics of fibrosing alopecia in a pattern distribution: A single-center, retrospective study
The study suggests fibrosing alopecia in a pattern distribution has distinct features and may vary by race.
research Dermpath Quiz: Which alopecia does the patient have?
The patient has frontal fibrosing alopecia (FFA).
research The Morphological Structure of Female Telogen Effluvium and Alopecia Areata Hairs According to Curriculum Contents of Beauty Art Department
