This study reported that hydrogels created from keratins extracted from human hair exhibit antibacterial properties and enhance tissue regeneration, suggesting their potential use in full-thickness skin repair, as demonstrated by increased collagen production and improved healing in vivo.

In this study, researchers developed injectable micropore-forming hydrogels that enhance tissue adhesion strength and promote wound healing by allowing better cell infiltration and inducing hair follicle regeneration in skin incision wound models.

This study found that high-concentration cell-free adipose extract effectively reduced collagen deposition and blood vessel formation in a rabbit ear model, showing promise for preventing and treating hypertrophic scars.

This study found that subcutaneous adipose tissue-derived extracellular vesicles (AT-EVs) protect skin from photodamage by enhancing fibroblast proliferation and reducing oxidative stress compared to those from adipose-derived stem cells.

This study found that inadequate thickness of deep dermal tissue in pigs is a key factor leading to fibrosis, with fibrosis likely serving a compensatory function for skin thickness.

This study found that dysregulation of the DNA damage response in stem cells is a common factor of aging, affecting tissues like the skin, brain, kidneys, and intestine.

Early-stage skin substitutes improve wound healing and skin structure.

This study found that microencapsulated dermal papilla cells in hyaluronic acid/collagen hydrogel retained their ability to initiate hair follicle regeneration, suggesting potential for alopecia treatment.

African spiny mice can regenerate skin and hair after wounds due to specific tissue mechanics.

This study found that an injectable hair material showed good biocompatibility in micropigs and effectively promoted dermal thickening, suggesting its potential as a new soft tissue filler.

This study found that an injectable material derived from hair shows good biocompatibility and promotes dermal thickness in pigs, suggesting potential as a new soft tissue filling agent.

This study observed that the mechanical connection between hair follicles and connective tissue in human fetal scalp skin is weaker than in the corresponding skin components, reflecting dynamic processes in hair growth.

This study observed that mink dermal collagen fibrils undergo structural changes during the hair cycle, with increased fiber thickness and bundle density as minks grow.

This study reported detailed three-dimensional ultrastructural observations of human hair and hair follicles using a modified preparation method, including morphological differences in hair bulb cell layers and surface projections on root sheath cells.

This review discusses strategies for regenerating cutaneous nerve function in burn patients and highlights the potential role of autologous skin-derived adult stem cells in improving sensory recovery, but reports no new experimental findings.

This study concludes that fetal skin cells can significantly enhance wound healing and reduce scarring when used to treat severe burns and various wounds in children.

In this study, ultrasound was found to alter the distribution of fibronectin in collagen hydrogels, leading to enhanced microtissue formation, suggesting potential applications in tissue engineering.

This study found that topical application of TGF-β mimic promoted enhanced wound healing and tissue regeneration in mice, suggesting its potential as a therapeutic option for improving wound healing.

This review discusses the impact of menopause-related oestrogen deficiency on skin ageing and suggests that oestrogen use may improve collagen and skin elasticity, but it reports no clinical trial results.

This review outlines the various processes activated by the peptide GHK-Cu in tissue remodeling and reports improvements in skin and wound healing but notes a need for further study to fully understand these mechanisms.

This review discusses the modern approach of skin tissue engineering for chronic wound treatment, focusing on bioengineered artificial skin substitutes and assessing innovations in biomaterials and cell use; it reports no new clinical results.

This study found that macrophages are crucial for skin regeneration during tissue expansion, as their depletion in rats led to inhibited skin growth and reduced secretion of key growth factors.

This review discusses the effects of oestrogen on skin ageing and highlights the need for large-scale clinical trials to evaluate postmenopausal oestrogen use, reporting no new findings.

This study found that "micro skin tissue columns" improved wound healing by enhancing re-epithelialization, collagen deposition, dermal remodeling, and reducing inflammation without causing long-term donor site morbidity.

This study demonstrated that using a perfusion culture bioreactor and 3D spheroid culture can enhance corneal endothelial cell expansion and support the construction of tissue-engineered corneal endothelial layers in vitro.

This study concluded that early-stage tissue-engineered skin substitutes, developed using skin progenitor cells, had a better graft efficiency and supported hair follicle formation, which may improve wound healing outcomes.

This study found that a single X-radiation treatment in rat skin reduced collagen concentration over multiple hair-cycles by diminishing the fibroblasts' capacity for proline hydroxylation, potentially contributing to delayed skin lesions.

This review discusses the role of tissue mechanics and extracellular matrix in skin aging processes and highlights potential therapeutic strategies, but reports no new clinical results.

This study found that combining TIMP-1 with graphene oxide promoted skin tissue regeneration in rats and provided sustained release of TIMP-1 over 40 days.

This report introduces a tissue-engineered nerve conduit combining hfNCSCs-derived neurons and acellular nerve grafts to potentially repair long-distance peripheral nerve injuries.
