This study found that Gelatinase A activity is linked to the absence of type VII collagen during human fetal skin development, indicating its role in remodeling the basement membrane zone.

African hair is more fragile due to its unique shape and internal structure.

This study examined the unique structural features of sinus hair follicles in the shrew Sorex unguiculatus, which suggest a specialization for vibration sensing.

This study introduces the term "hair matrix cyst" for a cyst with both pilomatricoma and epidermal cyst characteristics, highlighting its potential for misdiagnosis among similar skin conditions.

This review discusses the roles of tissue-specific and mesenchymal stromal cells in tissue repair and reparative disorders, highlighting potential therapeutic targets for muscle, heart, and lung tissues.

This study found that generating pluripotent stem cell-derived skin organoids in a 3D bioprinted hydrogel device improved keratinocyte differentiation and hair follicle formation while reducing necrosis.

This study observed that Merkel cells and their associated somatosensory axons in mouse skin exhibit significant plasticity, remodeling dynamically to maintain homeostasis. Axonal branching patterns were notably influenced by Merkel cells, suggesting epithelial-neural interactions play a key role in axonal plasticity and patterning.

This study demonstrated that in a mouse melanoma wound model, the MQ Microneedles effectively managed ROS levels to inhibit tumor growth and promote wound healing through light-controlled release.

This review explores the convergence of functional biomaterials, biosensing, and AI technologies in bioengineering, highlighting applications in cancer modeling and regenerative medicine, while addressing challenges like biofouling and dataset integration.

This study found that the NuMA protein's microtubule-binding domain is essential for proper spindle orientation and differentiation in keratinocytes, affecting skin and hair development in mice.

This study found that pen-type microwells enhanced hair follicle germ formation by promoting cell assembly, suggesting microwell array geometry significantly influences in vitro hair follicle development.

This study describes the structural composition of the skin's dermis in experimental animals, highlighting the arrangement of collagen, elastic, and reticular fibers as well as associated glands and muscles.

This study observed that increasing the γ-kerateine content in meta-kerateine materials led to reduced elasticity, solidity, and hydrolytic stability, and decreased hepatocyte attachment support.

This study found that medullary cell content in mammal hair evolves from an amorphous form to a biphasic phase, with human and anthropoid hair containing both macrofibrils and microfibrils.

In this study, mouse models of 22q11.2 deletion syndrome showed that growth issues in small embryonic thymuses were linked to mesenchymal cells, which could be corrected by substituting with normal mesenchyme.

This study developed thermo-reversible glycol chitosan hydrogels that effectively form and maintain 3D cell spheroids within one day, offering a simplified method for creating biologically realistic cultures for tissue regeneration and drug screening applications.

This study found that a silk fibroin/sodium alginate scaffold effectively delivers human umbilical mesenchymal stem cells to promote scarless wound healing and hair follicle regeneration in vivo by inducing specific cellular processes and mitigating endoplasmic reticulum stress.

This study observed that human hair keratin showed distinct morphological features depending on the dissolution speed, which could have potential applications in clinical settings for developing self-tendons.

This study demonstrated that a mechanical-assisted post-bioprinting strategy significantly increased cell numbers and enhanced regenerative capabilities in hollow hydrogel-based scaffolds for bone defect repair in vivo.

This review reports that combining adipose-derived stem cells with decellularized extracellular matrix enhances tissue repair by improving scaffold biological activity and promoting angiogenesis, integration, and functional regeneration across various tissues, while addressing challenges in traditional transplantation methods.

In this study, researchers found that the expression of vimentin, desmin, and laminin in rat skin contributes to cell structure and tissue integrity, with varying reactions across different cell types.

This study suggests that MMP-9 plays a significant role in extracellular matrix remodeling during hair canal formation in mice, as indicated by delayed hair shaft emergence and hair canal development in MMP-9 knockout mice.

This study found that fibronectin nanofiber dressings, made using rotary jet spinning, accelerated wound healing and improved tissue restoration in a full-thickness wound mouse model.

This study found that ossification in trichilemmal cysts may be more common than previously thought, often associated with cyst wall rupture, and reports a novel case of ossifying TC with extramedullary hematopoiesis.

In this study, NuMA's microtubule-binding domain was found to be crucial for correct spindle orientation and skin differentiation, with its loss leading to neonatal lethality in mice.

This study by Bansaccal et al. found that skin with higher levels of type I collagen density and elasticity in the dermis can inhibit basal cell carcinoma development and spread by acting as a natural barrier against cell reprogramming in mice.

In this study, highly dynamic remodeling was observed in mouse somatosensory axons and Merkel cells, indicating that epithelial-neural interactions help maintain homeostatic remodeling, with additional intrinsic neural mechanisms contributing to axonal plasticity.
