This study reports that follicular cells isolated from murine skin can regenerate hair follicles after being injected into nude mouse skin, with the regeneration process relying on cell interactions, recipient sites, and cell numbers.

This review highlights the therapeutic potential of various skin stem cell populations for tissue repair and regenerative medicine, but presents no new clinical findings.

People with acne have more CD4+ immune cells in their skin than healthy people.

In this study, researchers used single-cell RNA sequencing to define and locate three distinct cell states of melanocytes in mouse skin development, potentially aiding the understanding of abnormal melanocyte differentiation.

This study observed that patients with different types of alopecia exhibited variable epidermal thickness and consistent dermal changes, including hair follicle destruction and lymphohistiocytic infiltrates, which may suggest inflammation.

This study found that the lipid composition of the epidermis varies significantly throughout the hair growth cycle and after applying methylcholanthrene, with notable differences observed between hyperplastic and carcinomatous conditions.

This review outlines the various fibroblast subsets in the skin dermis, their origins, and their influence on epidermal stem cell behavior, highlighting the role of the local dermal niche in stem cell plasticity.

This study demonstrated that a c-Kit-CreER-driven mouse model confirms melanocyte stem cells as a genuine source of melanoma, paralleling human melanoma in heterogeneity and gene signatures.

This review discusses various methods for processing and separating human skin samples for research purposes, evaluating factors like processing time and cell viability, but reports no new experimental findings.

In this study, researchers found that wound healing in mouse skin recruits diverse fibroblasts, including myeloid-derived cells, which contribute to regenerating adipocytes.

This study found that adult mouse dermis can be reprogrammed by epidermal cues to resemble neonatal dermis, with changes in fibroblast proliferation and extracellular matrix composition.

This study found that human adipose-derived stem cells co-cultured on a collagen sponge scaffold showed increased differentiation into keratinocytes, suggesting potential for improved skin wound healing.

Sca-1+ cells in newborn mouse skin may become fat cells.

Early stage bald spots are linked to skin inflammation and damage to the upper part of the hair follicle.

This study developed microfluidic-assisted GelMA-MSC/HAD-EPC microspheres that efficiently generated hair follicles in nude mice, suggesting a promising strategy for advancing hair-regenerative medicine.

This study found that fibronectin-attached cell sheets significantly improved wound healing in vivo by increasing wound closure rates, reducing inflammation, and promoting tissue regeneration compared to conventional cell sheets.

Adult hair follicle cells can create new hair follicles from corneal cells with the right support.

This study found that murine epidermal stem cells implanted subcutaneously in a biodegradable carrier could survive and differentiate into structures resembling native dermis without significant rejection in recipient mice.

This study found that topical mesenchymal stem cell conditioned medium improved skin structure by increasing collagen fiber density, hair follicles, and blood vessel number in a mouse model of skin aging.

This study found that in alopecia areata, hair bulbs are blocked in an early growth stage due to impaired metabolic function in the surrounding connective tissue, hindering hair growth.

This study found that tissue-engineered skin using mouse fibroblasts successfully supported hair growth after grafting, but similar success was not observed using human fibroblast-derived tissue.

This study found that in skin blister healing, hair follicle development is compromised as stem cells repair wounds at the expense of morphogenesis gene expression.

This study developed a biomimetic 3D skin model with vascularization potential to assess the impact of nano-zinc oxide (nano-ZnO), finding that nano-ZnO significantly influenced genes related to apoptosis, inflammation, and oxidative stress in skin cells.

New methods for growing skin cells can improve skin grafts by building blood vessels within them.

This study reports that extracellular microvesicles isolated from stimulated dermal fibroblasts enhanced hair follicle growth ex vivo and identified norrin as a novel modulator in hair regeneration processes.

In this study, neonatal mouse mesenchymal cells showed hair-inducing capabilities, which were lost during in vitro propagation but could be partially restored through specific high-density culture methods.

This study used multi-scale hybrid models to explore how signaling factors affect skin wound healing and embryo development, suggesting that different levels of fibrin clot density influence scar formation.
