This study found that the CD44(+) ALDH(+) population of neonatal human keratinocytes exhibited enhanced stem cell properties, including significantly increased long-term epidermal regeneration and multipotency, compared to unfractionated cells.

This study identified specific markers that can distinguish between stem cells in different regions of human scalp hair follicles, offering potential strategies for cell sorting and purification based on these markers.

This review covers recent developments in inner ear therapeutics and gene delivery methods but reports no new clinical results; it highlights potential strategies for treating hearing and balance disorders.

This review discusses the paracrine properties of cardiac stem cells and pericytes in regenerative medicine for ischaemic diseases and reports no new clinical results.

In this randomized clinical trial, the authors reported that adipose-derived stem cell constituent extract topical solution increased hair density and thickness in patients with androgenetic alopecia over 16 weeks compared to placebo.

This review suggests that PRP injections may be effective in promoting hair regrowth, reducing hair loss, and increasing hair thickness in patients with androgenic alopecia.

This study achieved a first by successfully forming large quantities of dermal papilla spheroidal microtissues, which retained their hair induction potential, using a micropatterned culture system.

In this study, researchers observed that African spiny mice, Acomys cahirinus, are capable of regenerating skeletal muscle in dermal wound sites, unlike common mice, Mus musculus.

This study demonstrated that a 3D air–liquid culture system using Wnt-CM-treated cells can induce hair regeneration in nude mice and may facilitate large-scale preparation for hair loss treatment.

In this study, CD109 overexpression in transgenic mice led to reduced inflammation and improved collagen organization during wound healing without affecting wound closure.

This review discusses the latest understanding of androgenetic alopecia, including stem cell niches in hair follicles, and highlights emerging treatments like growth factors and platelet-rich plasma without new clinical findings.

This study found that human umbilical cord blood mesenchymal stem cells promoted hair growth by advancing anagen onset and increasing hair follicle regeneration in an in vivo model.

This study found that deleting the Hes1 gene disrupts hair regeneration by delaying anagen initiation and shortening the anagen phase, suggesting it's crucial for maintaining hair cycle homeostasis.

This source reviews Japan's extensive 2014 reforms and investments in regenerative medicine, exploring the government's initiatives to accelerate stem cell research while maintaining safety and efficacy.

This study suggests that miRNAs, particularly miR-195-5p, may regulate the loss of hair follicle inductivity in cultured dermal papilla cells by suppressing the Wnt/β-catenin pathway.

This study found that both allogeneic and xenogeneic small extracellular vesicles from adipose tissue similarly enhanced soft tissue regeneration and wound healing in rat models, implying similar therapeutic effects across species.

The researchers reported that minor salivary gland stem cells exhibit stem cell characteristics and respond to tobacco-derived carcinogens, implicating the transforming growth factor beta pathway in their maintenance.

This article discusses the importance of clinical biopreservation for cells and tissues in hair transplantation and regenerative medicine, reporting no new empirical findings.

This study found that neural crest-derived hair follicle cells in mice can differentiate into osteoblast-like cells, suggesting a potential application for bone regenerative therapies.

This review examines the recent progress in using bioactive molecules for skin regenerative medicine and reports no new clinical results; the authors suggest this method could become a promising strategy for in situ skin regeneration.

In this study, the researchers found that the effectiveness of a 1,550-nm fractional laser in promoting hair growth in mice depends on the specific combination of beam energy and density, with inappropriate settings potentially causing ulcers or hair follicle injury.

This study demonstrated that customized microneedle arrays can precisely induce targeted hair regeneration and improve hair quality in mice, potentially offering a personalized treatment approach for hair loss.

This study found that forming spheroids using silicone micro-wells improved the viability and neural differentiation potential of human adipose-derived stem cells after thawing.

This study reported that Indian hedgehog (Ihh) signaling plays a crucial role in regulating tumor progression and metastasis in epithelial cancers, with Ihh deficiency leading to increased malignancy and metastasis in mice.

This study found that SA-MS hydrogel released Mo4+ ions which promoted healing of disease-impaired wounds by enhancing cell proliferation and angiogenesis, and through its photothermal effects addressed skin cancer-impaired wounds in mice.

This study reported that a single local subcutaneous infusion of mesenchymal stromal cells from the human umbilical cord promoted wound healing, improved blood circulation, and reduced wound size in patients with chronic wounds without significant adverse effects over one year.

This study suggests that the secretome from amniotic fluid-derived mesenchymal stem cells overexpressing Nanog could stimulate hair growth and increase follicle density, potentially aiding in alopecia treatment.

This study found that while autonomous Sema3A expression limited keratinocyte migration and delayed wound healing, non-autonomous application of recombinant Sema3A with EGF enhanced wound repair in mice.
