This study reported that canine dermal papilla cells showed a distinct growth pattern and strong collagen IV and laminin staining compared to dermal fibroblasts.

This study successfully established a transgenic sheep fibroblast cell line expressing the spider dragline silk protein gene, laying groundwork for developing transgenic sheep with this capability in hair follicles.

In this study, myofibroblasts in rat cutaneous fibrosis were characterized by expressions of vimentin, α-SMA, and Thy-1, and may derive from pericytes or perifollicular dermal sheath cells.

This study found that DPP4 is significantly involved in matrix deposition and fibrosis in human skin fibroblasts, although the exact functions of DPP4 remain unclear.

This study found that selective adhesion to type IV collagen successfully enriched human hair follicle stem cells based on distinct adhesion properties and marker expressions.

Reactive lipids from aging cells change the extracellular matrix, affecting cell function and inflammation.

This study discusses the effects of collagen hydrolysates and the dipeptide Pro-Hyp on gene expression related to hair and epidermis development in mouse skin and reports no new clinical results.

This study found that COL17 plays a key role in regulating epidermal keratinocyte differentiation and proliferation, influencing the expression of differentiation markers and cellular growth in specific conditions.

This study found that in mice, type XVII collagen is essential for controlling epidermal cell proliferation through Wnt signaling, with its deficiency or altered distribution leading to skin hyperproliferation and aging-like changes.

Fibroblasts are crucial in scar formation and wound healing, with potential therapies aiming for scarless healing.

This study identified novel biomarkers through gene expression differences between keratinocytes and fibroblasts in newborn mice, which may aid in developing therapies for skin conditions.

This study found that fibroblasts from mature skin showed significantly reduced mechanical force production compared to young skin fibroblasts, suggesting age-related changes in cellular mechanical properties.

CCCA may be a fibroproliferative disorder, and anti-fibrotic therapies could help.

This animal study found that transparent porcine-derived Type I atelocollagen increases skin thickness and regenerates elastic fibers in aged mice, suggesting its potential as a skin booster for rejuvenation.

This study observed that 67 kDa keratin was expressed homogeneously only in epidermis derived from hair follicle explants, differing from other culture methods where expression was delayed and patchy.

In this study, researchers analyzing human fetal skin fibroblasts found eight distinct populations with developmental stage-specific abundance, identifying markers linked to fibroblast functions in blood vessel development, dermal layers, and hair follicle maturation.

This study found that TNC + fibroblasts are crucial in neuro-immune interactions in various skin diseases, particularly inflammation and tumors, by engaging extensively with immune cells and overexpressing inflammatory genes, suggesting their significant role in skin abnormalities.

This study found that TGF-β2 may enhance collagen expression and spheroid formation in human dermal papilla cells, which could improve their hair inductivity and maintenance.

This article reviews how aging affects skin and stem cells, but it contains no new research findings.

This study reported that plant-produced basic fibroblast growth factor effectively promoted cell proliferation and collagen production in vitro, suggesting potential applications in cosmetics for antiaging and hair growth.

This study found that dermal hair papilla and sheath cells have lower collagen secretion than fibroblasts, suggesting different functions, and that routine culture medium supports their optimal growth and proliferation.

This study found that oral collagen peptides increased expression of genes associated with epidermis development and the hair cycle in hairless mice, providing insights into their potential skin benefits.

This study found that in murine dermis, fibroblast state switching between proliferation and ECM deposition plays a crucial role in tissue architecture and wound healing.

This review discusses the development, lineages, functions, and roles of fibroblasts in fibrosis across four organs, highlighting their capabilities in tissue repair and contributions to fibrotic disorders when aberrantly activated, but it reports no new experimental findings.

This study found that in a rat skin model, fat cells inhibited the proliferation of organoid hair follicle cells and fibroblasts but may have accelerated hair follicle cell differentiation.

This study found that dermal papilla and dermal sheath cells from human scalp tissue differ from interstitial dermal fibroblasts in morphology and produce varying levels of TGF-beta 2.

This review explores the physiological roles of collagen XVII in the epidermis, its involvement in stem cell maintenance, and its connections with signaling pathways, but it reports no new results.
