This study found that injecting thymus gland extracts into albino rats significantly accelerated growth and morphological differentiation across generations, including earlier sexual maturation and development of features like hair and teeth.

In this study, Sox13 was identified as a novel marker for early hair follicle development and differentiation in mice, though it appears to be dispensable for overall epidermal and adnexal development.

In this study, researchers used a hypospadiac rat model to demonstrate abnormal genital development, similar to human penoscrotal hypospadias, highlighting the model's value for studying penile growth and differentiation.

This study observed that undifferentiated matrix cells at the base of the hair follicle differentiate into the medulla, cortex, cuticle, and inner root sheath cell types through specific morphological changes.

This review introduces the morphological and molecular principles of hair follicle development but reports no new experimental results, focusing on recent insights and forming a working hypothesis.

This study found that the prenatal skin development in Red Sokoto goats undergoes significant morphological changes across gestational stages, which may be important for their adaptation and thermoregulation after birth.

This study found that the co-ablation of C/EBPalpha and C/EBPbeta in adult mouse skin disrupted sebocyte differentiation and epidermal homeostasis, highlighting their critical roles in these processes.

This study found that minoxidil concentrations at 1, 10, and 100 μg/ml inhibited the proliferation of cultured hair follicle cells without causing morphological changes.

This study found that differentiated airway epithelial cells can revert into functional stem cells in vivo, suggesting a more general role for this dedifferentiation process in tissue regeneration in higher vertebrates.

This study successfully improved methods for isolating, culturing, and purifying rat hair follicle stem cells, demonstrating their high purity, strong proliferation, and potential for adipogenic and osteogenic differentiation in vitro, which could support advancements in tissue engineering.

This study demonstrated that human dermal mesenchymal stem cells can be differentiated into cardiomyocytes using 5-azacytidine, suggesting potential future applications for treating myocardial infarction.

This study found that non-vitiliginous melanocyte stem cells from vitiligo patients were unaffected by the disease and could effectively differentiate into melanin-producing melanocytes, suggesting their potential for use in cellular therapy for vitiligo repigmentation.

This review synthesizes current knowledge on choriogenesis, the final stage of oogenesis in insects, by exploring the role of follicle cells, regulatory mechanisms of gene expression, and the biochemical makeup of the eggshell, while also highlighting structural diversity and adaptations across insect species.

This study found that the Nod factor from Rhizobium meliloti, particularly at concentrations of 10-8 and 10-7 M, induced specific membrane depolarization and root-hair deformation in Medicago sativa, depending on the stage of cell differentiation.

This study found distinct sex-based differences in the microscopic characteristics of scalp hair among a Nigerian population, providing valuable forensic data specific to this group.

In this study, researchers found that bulge cells cultured from rat hair follicles demonstrated stem cell characteristics and could differentiate into neural and glial lineages.

This study found that hair follicle stem cells from the bulge region in mice and humans can be isolated and cultured to maintain their phenotype and high proliferative capacity, suggesting their potential as an accessible source for tissue engineering and regenerative therapies.

This study found that overexpression of activin in transgenic mice led to enhanced granulation tissue formation after skin injury due to changes in keratinocyte proliferation and differentiation.

In this study, chick embryo extract enhanced neuronal differentiation and trophic factor expression in rat hair follicle stem cells, suggesting potential improvements for stem cell therapies in neurodegenerative diseases.

This study observed increased metallothionein expression in regenerating liver and hyperplastic mouse skin, suggesting a potential role in cellular proliferation and differentiation.

This study detailed the developmental stages of the buffalo mammary gland during prenatal growth, identifying key morphological features at various gestation lengths.

This study revisits and reproduces Felix Pinkus' concept of the vitreous membrane in hair follicles, suggesting these structures may play a role in differentiation or nutrition due to their location in metabolically dynamic regions.

This study found that trichoscopy is highly effective for diagnosing different types of alopecia, showing an average diagnostic accuracy of 90–95%, with specific features aiding in differentiating forms like androgenetic alopecia and alopecia areata. New technologies and AI improve interpretation objectivity, suggesting expanded clinical integration.

This study found that hair germ and epidermal basal cells differ in keratin expressions in rat hair tissues, with hair-specific keratins appearing after the differentiation of each layer.

In this study, LC-OCT imaging was found to noninvasively identify specific features of cicatricial alopecia due to lupus erythematosus, such as hyperreflective collagen fibers, which may aid in distinguishing it from other types of scarring alopecia.
