This scoping review explores devices that mechanically process lipoaspirate for cell-based therapies but finds insufficient evidence to determine their clinical effectiveness due to lack of standardization and data variability.

Stem cells compete for space using cell adhesion, and mutations can affect their competitive success, with implications for tissue health and disease.

This study concluded that the receptor-like kinase ERULUS, regulated by auxin, is crucial for modulating cell wall composition and pectin dynamics during root hair growth in Arabidopsis.

In this study, transgenic male mice over-expressing the androgen receptor in mesenchymal stem cells showed reduced fat mass and improved glucose clearance, suggesting enhanced androgen sensitivity may alter body composition.

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 reported that depleting the pro-apoptotic protein Bax in hair follicle stem cells enables these cells to kill nearby viable cells by sequestering TNFα, which increases the stem cell pool and accelerates tissue regeneration, suggesting potential implications for therapies targeting tissue repair and cancer.

This study reveals an antagonistic competition between BMP and Wnt signaling within stem cells, influencing their fate towards hair germ characteristics based on the BMP/Wnt activity ratio.

This study found that injury-induced proliferation of wild-type cells can suppress oncogenic growth in Ras-mosaic skin.

This review discusses the role of BMP/Wnt signaling in regulating stem cell homeostasis and activation but reports no new experimental findings.

This study found that γδ T cells play a role in regulating stromal behavior, influencing the composition and vascularity of fibrotic tissues during the foreign body response.

Aged skin heals slower due to more inflammation and disrupted cell communication.

This study explores the role of cell competition in maintaining genomic quality in epidermal stem cells and proposes that this process might influence cancer development in skin tissues.

This review synthesizes current knowledge on choriogenesis, the final stage of oogenesis in insects, by exploring the role of follicle cells, regulatory mechanisms of gene expression, and the biochemical makeup of the eggshell, while also highlighting structural diversity and adaptations across insect species.

Lustre mutant sheep have normal hair structure and proteins but differ in felting properties.

Skin organoids can mimic human skin responses to injury and inflammation, making them useful for studying skin diseases and testing treatments.

This review highlights emerging evidence that biophysical and metabolic cues, such as oxygen levels and tissue mechanics, significantly influence skin stem cell behavior, which is crucial for developing advanced wound healing therapies beyond traditional infection and inflammation control.

This study found that in mice, low-dose irradiation causes stem cells in hair follicles to undergo chromatin alterations, which may eventually lead to long-term functional loss in tissues or organs.

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 discusses the use of platelet-rich plasma therapy in aesthetic anti-aging treatment, highlighting its reported safety and effectiveness in skin regeneration, but presents no original clinical results.

This study found that Runx1 in hair follicle stem cells modulates lipid metabolism, impacting membrane organization and enhancing signal transduction for cell proliferation in both normal and cancer epithelial cells.

In this study, hair follicle-derived mesenchymal stromal cells showed potential for immunomodulation, with equivalent or superior responses compared to those from adipose tissue, suggesting a promising alternative cell source.

In this study, researchers demonstrated that the expression of the oncogene SmoM2 leads to basal cell carcinoma in the ear epidermis of mice but not in the back skin, with differences in susceptibility linked to the composition of the extracellular matrix.

This study found that hair follicle and interfollicular epidermis stem cells contribute differently to skin regeneration, with their persistence influenced by factors like spatial constraints and competition moderated by Notch suppression.

This review explains the mechanical composition and molecular interactions that determine hair's mechanical properties, without providing any new experimental findings.

In this animal study, researchers found that the simultaneous deletion of ERBB2 and ERBB3 in mice results in impaired skin differentiation, inflammation, and sebaceous gland alteration, leading to skin lesions, while highlighting potential side effects in cancer therapies targeting these receptors.

This study explored the carbohydrate composition of plasma cell membranes in human embryonic epidermis over various gestational ages and found specific patterns that may inform future diagnostic and therapeutic approaches for dermatoses.

This study identified four hub genes that are closely linked to the causative factors of androgenetic alopecia, suggesting potential diagnostic and therapeutic targets.

This study found that epithelial cells in the skin of live mice regulate the density and spatial organization of immune cells, which actively maintain their position despite constant cell turnover.

This chapter reviews the clinical effects of androgens like testosterone and its metabolites on various body systems and life stages, but reports no new results.

In this clinical study of 98 patients with focal alopecia, combined laser therapy, which included laser plasma therapy and percutaneous laser irradiation of blood, was reported to alleviate inflammation, promote hair growth, and restore trace elements in affected areas.
