This study found that knocking out the integrin β1 subunit in induced pluripotent stem cells enhanced their migration and improved their wound-healing effects in a mouse model.

This study found that adipose-derived stem cells from adult guinea pigs can differentiate into hair cell-like cells in vitro, suggesting potential use in tissue engineering.

This review discusses the potential of secretome derived from stem cells for treating alopecia areata and reports no new clinical results; the authors suggest the need for further human trials.

This study found that hair follicle stem cells in the hairpoor mouse, a model for Marie-Unna hypotrichosis, lose their quiescent state, leading to a disordered hair cycle and contributing to alopecia.

This review discusses the characteristics and potential applications of epidermal stem cells in dermatology, without providing new clinical results.

This review discusses advancements and challenges in laboratory-based tissue-expansion and transplantation techniques for facial wound healing, noting potential for stem cell therapies but highlighting the ongoing absence of skin features like hair follicles in cultured grafts.

In this study, researchers evaluated hair follicle transplantation techniques and reported that challenges such as limited follicle supply and low follicle survival rates often limit patient satisfaction, but advances in regenerative medicine may offer promising new solutions.

This article provides industry updates on stem cell research and regenerative medicine from December 2019 and reports no new research findings.

This review discusses the potential of stem cell therapies for regenerating hair in nonautoimmune hair loss and calls for more studies to evaluate their efficacy.

Fat-derived stem cell therapies can potentially increase hair growth and thickness in people with hair loss.

Fat-derived stem cell therapies can potentially increase hair growth and thickness in people with hair loss.

This review article discusses recent advances in stem cell-based therapies for Alopecia Areata, noting preliminary clinical trials show significant hair regrowth, but emphasizes the need for thorough evaluation of long-term safety and efficacy.

In this study, the authors reported that combining PMSC-secretome and Wnt10b in a GelMA hydrogel scaffold promoted effective hair follicle biofabrication and hair growth in a small in vivo experiment. They emphasized the need for larger studies to confirm these results.

This study found that exosomes from human umbilical cord mesenchymal stem cells significantly promoted hair follicle growth and enhanced the transition to the growth phase in a model of androgenetic alopecia, by enriching specific microRNAs that activate key pathways involved in hair regeneration.

The researchers reported that disrupting ATRA signaling by deleting RDHE genes in the hair follicle led to altered hair follicle cycles, composition, and gene expression, indicating RDHEs' role in hair follicle signaling coordination.

This study found that conditioned medium from human dental pulp stem cells (particularly under hypoxic conditions) improved keratinocyte survival and hair regrowth in a chemotherapy-induced alopecia mouse model and did not promote tumor growth, suggesting potential for safe therapeutic use.

This systematic review found that both cellular and acellular stem cell-based therapies are safe and able to improve hair regeneration and density in patients with androgenic alopecia, although some results may be temporary.

This study using human and animal models found that adipose-derived stem cell exosomes promoted hair growth and counteracted dihydrotestosterone's inhibitory effects, suggesting potential therapeutic applications for androgenetic alopecia.

This study found that increased expression of the stem cell factor receptor c-kit was associated with alopecia areata and androgenic alopecia, suggesting it may have a predictive role in progression among high-risk patients.

This study found that canine hair follicle stem cells in vitro expressed markers associated with multipotency, suggesting their potential role in the hair cycle.

In this study, researchers demonstrated that the Id2 gene acts as a direct target and effector of BMP signaling, playing a key role in maintaining quiescence in hair follicle stem cells in vivo.

This review suggests that stem cells might be a promising addition or alternative to standard treatments for androgenic alopecia, but larger studies are needed to confirm these findings.

The conclusion is that the dermal papilla is crucial for hair follicle regrowth, and hair follicles undergo significant structural changes in addition to cell division during regeneration.

This study reported that disrupting ephrin-Eph interactions in adult mouse skin doubled cell proliferation in the hair follicle and epidermis, suggesting ephrins as negative regulators of proliferation.

In this study, researchers found that glycan profiles in epidermal stem cells differed between young and old mice, suggesting these changes may serve as molecular markers for aging.

This review discusses the diverse roles and characteristics of epidermal and dermal stem cells in skin regeneration and aging, highlighting their potential applications in regenerative medicine and reports no new clinical results.

This study found that Lgr5 and Lgr6 stem cells both activated wound-healing genes, but only Lgr5 stem cells changed their identity to contribute to new skin formation during wound repair.

This study found that squamous cell carcinomas from hair follicle stem cells are more prone to epithelial to mesenchymal transition and metastasis than those from interfollicular epidermis, due to distinct chromatin landscapes.

In this study, researchers successfully derived skin organoids from mouse pluripotent stem cells that spontaneously produce hair follicles, potentially aiding in hair growth research and in vitro drug testing.

This review discusses advancements in plant cell culture technology for producing potent natural cosmetic ingredients and reports no new experimental results.
