The study found that conditioned medium from placental cells and sub-cultured placental tissue promoted angiogenesis in HUVECs, with early pregnancy cells showing more significant effects than those from full-term pregnancy.

This case report highlighted two atypical childhood alopecia cases: congenital atrichia without papules and Bjornstad syndrome with alopecia areata; emphasizing diagnostic challenges, notably the absence of keratotic papules usually associated with congenital atrichia and the presence of alopecia areata in Bjornstad syndrome.

Immunocompromised patients can develop skin and hair issues due to a virus.

This study describes a system for generating hair follicles from dissociated cells in mice, suggesting that successful development requires a foundational epithelial platform.

This study found that trichohyalin is expressed in various normal and pathological epithelia beyond hair follicle cells, where it is uniquely associated with filaggrin, suggesting a specific role in aggregating K6/K16-containing intermediate filaments.

This study reviewed the usefulness of trichoscopy in diagnosing and monitoring alopecia areata, noting that the technique identifies specific hair features like yellow and black dots, which are linked to the disease's chronic nature and treatment response.

In this study, a rare case of a trichilemmal cyst in a 6-year-old's upper eyelid was observed; it was identified through histopathological examination after excision, highlighting the importance of considering trichilemmal cysts in atypical pediatric eyelid swellings.

This review discusses the use of trichoscopy as a valuable diagnostic and prognostic tool for various hair and scalp disorders, reporting no new clinical results.

This article reviews trichoscopic techniques for diagnosing common hair loss conditions and presents a revised algorithm for identifying specific features of cicatricial and noncicatricial alopecia, but reports no new clinical results.

This article reviews the complexities and challenges in hair transplant procedures, emphasizing the role of micro-inflammation and the usefulness of trichoscopy for detecting complications, and reports no new clinical results.

This study found that trichoscopic examination can effectively differentiate between alopecia areata and trichotillomania, as specific features such as black dots and exclamation marks favor alopecia areata while hair breaking at various lengths and several unique patterns are exclusive to trichotillomania.

This article reports no new clinical findings but discusses two rare dermatological conditions, trichostasis spinulosa and eruptive vellus hair cysts, and their simultaneous occurrence.

In this study, hair shafts from trichothiodystrophy patients with ERCC2 mutations revealed abnormal cuticle structures and protein imbalances compared to normal hair shafts.

In this study, researchers documented several trichoscopic features that were statistically significant indicators of alopecia and scalp disorders compared to healthy controls.

This study found that human trichohyalin has a unique protein sequence potentially contributing to at least three important functions in hair follicle and epidermal cells.

TCHHL1 is a protein important for hair growth, found in hair follicles.

This study found that trichoscopy is a useful tool in differentiating between alopecia areta and trichotillomania on the eyebrows based on distinct hair and follicle features.

This study concluded that trichoscopy is a reliable, non-invasive, and faster diagnostic method for ambiguous cases of alopecia.

This review discusses the usefulness of trichoscopy in diagnosing and managing scalp and hair disorders, reporting it as a valuable tool for linking clinical and histological findings.

This study observed that hair follicle cuticular cells undergoing keratinization were significantly thicker than those in a normal hair shaft, due to incomplete loss of cytosol.

This article reports an unprecedented case of trichofolliculoma in the gluteal area, previously unreported in English literature.

This study proposed that the tiger tail phenomenon in trichothiodystrophy hair is caused by regular undulations of hair fibers, altering the optical properties seen under polarized light.

In this study, a system was developed utilizing advanced image processing to analyze hair and scalp conditions, aiding professionals in diagnosing diseases like alopecia and monitoring treatment by extracting and comparing key parameters from microscopic images.

This study demonstrates that the trichohyalin gene is located at chromosomal region 1q21, where several other genes related to epidermal differentiation also map.

In this study, trichoscopy revealed hair shaft abnormalities similar to those seen in alopecia areata and chemotherapy-induced alopecia in patients over 12 months following hair restoration surgery.

This study documents that trichohyalin acts as a multi-functional cross-bridging protein in the inner root sheath of mouse hair follicles, enhancing mechanical strength by linking keratin filaments to the cell envelope.

This study in Chennai, India, found that while some trichoscopic patterns are specific, many overlap across different scalp dermatoses, highlighting the importance of dermatologists staying informed about the latest findings.

This review discusses the application of trichoscopy in diagnosing various hair and scalp diseases and reports no new clinical results; the authors emphasize its role as a non-invasive diagnostic tool.

This study suggests that pilomatricoma can differentiate towards various hair follicle structures, including hair matrix, hair cortex, follicular infundibulum, outer root sheath, and hair bulge.
