Abstract:
Glycosaminoglycans (GAGs) and associated proteoglycans have important functions in homeostatic maintenance and regenerative processes (e.g., wound repair) of the skin. However, little is known about the role of these molecules in the regulation of the hair follicle cycle. Here we report that growing human hair follicles ex vivo in a defined GAG hydrogel mimicking the dermal matrix strongly promotes sustained cell survival and maintenance of a highly proliferative phenotype in the hair bulb and suprabulbar regions. This significant effect is associated with the activation of WNT/β-catenin signa

Abstract:
Acne-prone skin is associated with dysbiosis involving Cutibacterium acnes (C. acnes) and Staphylococcus epidermidis (S. epidermidis) causing increased seborrhea in sebaceous glands (SG) and inflammation. Human primary sebocytes were cultivated using 1.106 UFC/mL C. acnes Type IA (facial acne, ATCC6919) and/or 1.105 UFC/mL S. epidermidis (unknown origin, ATCC12228) for 48 h in our SEB4GLN-optimized media without antibiotics. Bacteria and sebocytes were enumerated and assessed to determine their viability. Lipid production was imaged and quantified via Nile Red staining. SG with hair follicles

Abstract:
The growth of solid tumors is greatly influenced by stromal components including cancer-associated fibroblasts (CAFs) and desmoplastic matrix through both immune-dependent and immune-independent mechanisms. Fibroblast activation protein (FAP) is a stromal cell target that is selectively expressed at high levels on the cell surface of CAFs. We previously established an ex vivo retroviral-transduced CAR T cell approach to target FAP+ CAFs that resulted in depletion of FAP+ stromal cells, disruption of desmoplastic matrix, enhanced immune infiltration, and inhibition of tumor growth.

Abstract:
We report for the first time the successful maintenance and growth of human hair follicles in vitro. Human anagen hair follicles were isolated by microdissection from human scalp skin. Isolation of the hair follicles was achieved by cutting the follicle at the dermo-subcutaneous fat interface using a scalpel blade. Intact hair follicles were then removed from the fat using watchmakers' forceps. Isolated hair follicles maintained free-floating in supplemented Williams E medium in individual wells of 24-well multiwell plates showed a significant increase in length over 4 days.

Abstract:
Hirsutism is an unpleasant condition that affects a large number of women. Hirsutism can make females feel exceedingly self-conscious, jeopardizing their sense of femininity as well as their self-esteem. They are employing established treatments without evaluating their negative consequences, necessitating the development of new procedures. EFH loaded solid lipid microparticles (EFH-SLM) were manufactured using the solvent evaporation technique using polymers. Hair regrowth investigations in healthy Swiss albino female mice were carried out ex-vivo. Animals treated with EFH-Cream and EFH-SLM-C

Allium tuberosum Rottler ex Spreng(ATRES) has been used as a traditional medicine for the treatment of abdominal pain, diarrhea, and asthma. In this study, we investigated the hair growth promoting activities of ATRES on telogenic C57BL6/N mice. Hair growth was significantly increased in the dorsal skin of ethanol extract of ATRES treated mouse group compared with the control mouse group. To enrich the hair promoting activity, an ethanol-insoluble fraction was further extracted in sequence withn-hexane, dichloromethane, ethyl acetate,n-butanol, and distilled water.

Abstract:
Hair loss, often called alopecia, is characterized by excessive hair loss. One way to treat hair loss is to use hair tonic preparation. This study aimed to determine the effect of a combination of hair tonic cinnamon essential oil and candlenut essential oil on hair growth. The research method used included physical evaluation of the hair tonic preparation formulation by examining the physical quality, homogeneity, pH, viscosity, and stability of the hair tonic preparation. The effectiveness of hair growth was evaluated in vivo in rabbits. Its effectiveness measures hair growth and weight. Bas

Abstract:
Plakoglobin regulates cell adhesion by providing a modulatable connection between both classical and desmosomal cadherins and their respective cytoskeletal linker proteins. Both plakoglobin and the related protein β-catenin are posttranscriptionally upregulated in response to Wnt-1 in cultured cells. Upregulation of β-catenin has been implicated in potentiating hyperproliferation and tumor formation. To investigate the role of plakoglobin in these functions we expressed a full-length (PG) and an NH2-terminally truncated form of plakoglobin (ΔN80PG) in mouse epidermis and hair follicles, tissue

Alopecia, a prevalent yet challenging condition with limited FDA-approved treatments which is accompanied by notable side effects, necessitates the exploration of natural alternatives. This study elucidated the hair growth properties of Gynostemma pentaphyllum leaf hydrodistillate (GPHD) both in vitro and in vivo. Furthermore, damulin B, a major component of GPHD, demonstrated hair growth-promoting properties in vitro. Beyond its established anti-diabetic, anti-obesity, and anti-inflammatory attributes, GPHD exhibited hair growth induction in mice parallel to minoxidil. Moreover, it upregulate

The aim of this study was to investigate the effect of Sargassum fusiforme extract (SFE) on melanogenesis and its mechanism both in vitro and ex vivo. The melanogenic-inducing effect of SFE was evaluated using a melanin contents assay and a cellular tyrosinase activity assay. To investigate whether SFE could protect melanocytes against oxidative stress, hydrogen peroxidase was used. The molecular mechanism underlying the effect of SFE on melanogenesis was determined via Western blot analysis of tyrosinase, a microphthalmia-associated transcription factor (MITF), and a phosphorylated cAMP respo
