Abstract
BACKGROUND Photoaging is a degenerative biological process that affects the quality of life. It is caused by environmental factors including ultraviolet radiation (UVR), deep skin burns, smoking, active oxygen, chemical substances, and trauma. Among them, UVR plays a vital role in the aging process. AIM With the continuous development of modern medicine, clinical researchers have investigated novel approaches to treat aging. In particular, mesenchymal stem cells (MSCs), non-coding RNAs are involved in various physiological processes have broad clinical application as they have the advantages of convenient samples, abundant sources, and avoidable ethical issues. METHODS This article reviews research progress on five types of stem cell, exosomes, non-coding RNA in the context of photoaging treatment: adipose-derived stem cell, human umbilical cord MSCs, epidermal progenitor cells, keratinocyte stem cells, and hair follicle stem cells (HFSCs). It also includes stem cell related exosomes and their non-coding RNA research. RESULTS The results have clinical guiding significance for prevention and control of the onset and development of photoaging. It is found that stem cells secrete cytokines, cell growth factors, non-coding RNA, exosomes and proteins to repair aging skin tissues and achieve skin rejuvenation. In particular, stem cell exosomes and non-coding RNA are found to have significant research potential, as they possess the benefits of their source cells without the disadvantages which include immune rejection and granuloma formation.

Exosomes derived from human adipose-derived stem cells alleviate hepatic ischemia-reperfusion (I/R) injury through the miR-183/ALOX5 axis. FASEB J 2023; 37:e22782. [PMID: 36786721 DOI: 10.1096/fj.202200277r] [Citation(s) in RCA: 8] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2022] [Revised: 11/10/2022] [Accepted: 01/09/2023] [Indexed: 02/15/2023]
Abstract
Ischemia-reperfusion (I/R) injury is a crucial factor causing liver injury in the clinic. Recent research has confirmed that human adipose-derived stem cells (ADSCs) can differentiate into functional hepatocytes. However, the mechanism of the effects of ADSCs in the treatment of liver injury remains unclear. The characteristics of ADSCs were first identified, and exosome-derived ADSCs were isolated and characterized. The function and mechanism of action of miR-183 and arachidonate 5-lipoxygenase (ALOX5) were investigated by functional experiments in HL-7702 cells with I/R injury and in I/R rats. Our data disclosed that exosome release from ADSCs induced proliferation and inhibited apoptosis in HL-7702 cells with I/R injury. The effect of miR-183 was similar to that of exosomes derived from ADSCs. In addition, ALOX5, as a target gene of miR-183, was involved in the related functions of miR-183. Moreover, in vivo experiments confirmed that miR-183 and exosomes from ADSCs could improve liver injury in rats and inhibit the MAPK and NF-κB pathways. All of these findings demonstrate that exosomes derived from ADSCs have a significant protective effect on hepatic I/R injury by regulating the miR-183/ALOX5 axis, which might provide a therapeutic strategy for liver injury.

Abstract
BACKGROUND An increasing number of studies have reported that exosomes from adipose-derived stem cells (ADSCs) have antioxidant and anti-inflammatory properties. In the present study, we aimed at elucidating the potential therapeutic mechanism underlying ADSC exosomes in ultraviolet B-light (UVB)-induced skin injury. METHODS We isolated the exosomes from ADSCs and hypoxia-pretreated ADSCs. High-throughput sequencing was applied to identify differential circRNA expression. Then, a UV-induced murine skin injury model was constructed and the therapeutic effect of exosomes was determined using immunofluorescence and ELISA. The regulatory mechanism was demonstrated using luciferase reporter analysis and an in vitro experiment. RESULTS Exosomes from hypoxia-pretreated ADSCs inhibited UVB light-induced vascular injury by reversing ROS and inflammatory factor expression. High-throughput sequencing showed that exosomes from hypoxia-pretreated ADSCs (HExo) improved UV-induced skin damage via delivery of circ-Ash1l. Downregulation of circ-Ash1l inhibited the therapeutic effect of HExo on UV-induced skin damage. It was further shown that GPX4 and miR-700-5p were circ-Ash1l downstream targets. MiR-700-5p overexpression or GPX4 downregulation inhibited the circ-Ash1l protective effects of UV-induced endothelial progenitor cell (EPC) damage. CONCLUSION Thus, exosomes from hypoxia-pretreated ADSCs attenuated UV light-induced skin injury via circ-Ash1l delivery and ferroptosis inhibition.

Stem Cell Res Ther 2022; 13:435. [PMID: 36056394 PMCID: PMC9438153 DOI: 10.1186/s13287-022-03137-y] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2022] [Accepted: 08/14/2022] [Indexed: 01/10/2023] Open
Abstract
Background Skin ageing caused by long-term ultraviolet (UV) irradiation is a complex biological process that involves multiple signalling pathways. Stem cell-conditioned media is believed to have anti-ageing effects on the skin. The purpose of this study was to explore the biological effects of UVB irradiation and anti-photoaging effects of human umbilical cord mesenchymal stem cell-conditioned medium (hUC-MSC-CM) on HaCaT cells using multi-omics analysis with a novel cellular photoaging model.
Methods A cellular model of photoaging was constructed by irradiating serum-starved HaCaT cells with 20 mJ/cm2 UVB. Transcriptomics and proteomics analyses were used to explore the biological effects of UVB irradiation on photoaged HaCaT cells. Changes in cell proliferation, apoptosis, and migration, the cell cycle, and expression of senescence genes and proteins were measured to assess the protective effects of hUC-MSC-CM in the cellular photoaging model. Results The results of the multi-omics analysis revealed that UVB irradiation affected various biological functions of cells, including cell proliferation and the cell cycle, and induced a senescence-associated secretory phenotype. hUC-MSC-CM treatment reduced cell apoptosis, inhibited G1 phase arrest in the cell cycle, reduced the production of reactive oxygen species, and promoted cell motility. The qRT-PCR results indicated that MYC, IL-8, FGF-1, and EREG were key genes involved in the anti-photoaging effects of hUC-MSC-CM. The western blotting results demonstrated that C-FOS, C-JUN, TGFβ, p53, FGF-1, and cyclin A2 were key proteins involved in the anti-photoaging effects of hUC-MSC-CM. Conclusion Serum-starved HaCaT cells irradiated with 20 mJ/cm2 UVB were used to generate an innovative cellular photoaging model, and hUC-MSC-CM demonstrates potential as an anti-photoaging treatment for skin.

A dopamine-methacrylated hyaluronic acid hydrogel as an effective carrier for stem cells in skin regeneration therapy. Cell Death Dis 2022; 13:738.

Abstract
Adipose-derived stem cells (ADSCs) show potential in skin regeneration research. A previous study reported the failure of full-thickness skin self-repair in an injury area exceeding 4 cm in diameter. Stem cell therapies have shown promise in accelerating skin regeneration; however, the low survival rate of transplanted cells due to the lack of protection during and after transplantation leads to low efficacy. Hence, effective biomaterials for the delivery and retention of ADSCs are urgently needed for skin regeneration purposes. Here, we covalently crosslinked hyaluronic acid with methacrylic anhydride and then covalently crosslinked the product with dopamine to engineer dopamine-methacrylated hyaluronic acid (DA-MeHA). Our experiments suggested that the DA-MeHA hydrogel firmly adhered to the skin wound defect and promoted cell proliferation in vitro and skin defect regeneration in vivo. Mechanistic analyses revealed that the beneficial effect of the DA-MeHA hydrogel combined with ADSCs on skin defect repair may be closely related to the Notch signaling pathway. The ADSCs from the DA-MeHA hydrogel secrete high levels of growth factors and are thus highly efficacious for promoting skin wound healing. This DA-MeHA hydrogel may be used as an effective potential carrier for stem cells as it enhances the efficacy of ADSCs in skin regeneration.

Abstract
Skin is a natural barrier of human body and a visual indicator of aging process. Exposure to ultraviolet (UV) radiation in the sunlight may injure the skin tissues and cause local damage. Besides, it is reported that repetitive or long-term exposure to UV radiation may reduce the collagen production, change the normal skin structure and cause premature skin aging. This is termed "photoaging". The classical symptoms of photoaging include increased roughness, wrinkle formation, mottled pigmentation or even precancerous changes. Mesenchymal stem cells (MSCs) are a kind of cells with the ability of self-renewal and multidirectional differentiation into many types of cells, like adipocytes, osteoblasts and chondrocytes. Researchers have explored diverse pharmacological actions of MSCs because of their migratory activity, paracrine actions and immunoregulation effects. In recent years, the huge potential of MSCs in preventing skin from photoaging has gained wide attention. MSCs exert their beneficial effects on skin photoaging via antioxidant effect, anti-apoptotic/anti-inflammatory effect, reduction of matrix metalloproteinases (MMPs) and activation of dermal fibroblasts proliferation. MSCs and MSC related products have demonstrated huge potential in the treatment of skin photoaging. This narrative review concisely sums up the recent research developments on the roles of MSCs in protection against photoaging and highlights the enormous potential of MSCs in skin photoaging treatment.

Abstract
Interventions for extrinsic aging can be implemented, but these must address photoaging, which is the primary cause of extrinsic aging. Pigmentation due to photoaging depends on the duration and intensity of sun exposure. This study investigated the relationship between adipose-derived mesenchymal stem cells (ASCs) and photoaging pigmentation, and the underlying mechanism of action by establishing a photoaging pigmentation model using various treatments and exposure options in a guinea pigs. The energy dose of each UVB irradiation was 120 mJ/cm2 and the total dose of irradiation was 360 mJ/cm2. After successfully establishing the photoaging model, ASCs (1×106) in an balanced salt solution (0.9 ml), balanced salt solution (0.9 ml), and bFGF (9 μg) mixed with an balanced salt solution (0.9 ml) were injected intradermally in ten guinea pigs. ELISA, macroscopic skin and histological observations, and Masson-Fontana staining were done. At 2 and 4 weeks post-injection, noticeable changes were observed. Guinea pigs receiving ASCs injections displayed significantly lower visible skin scores while the melanin content continued to decrease. Somewhat improved histopathological morphology, including epidermal thinning, dermal thickening, and little inflammatory cell infiltration was observed immediately after and up to 4 weeks of ASCs injection. Melanocortin 1 receptor (MC1R) and alpha-melanocyte test hormone (alpha-MSH) levels reduced significantly, and basic fibroblast growth factor (bFGF) levels increased significantly immediately after and up to 4 weeks of ASCs injection. The MC1R and alpha-MSH levels reduced significantly immediately after and up to 4 weeks of bFGF injection. Briefly, intradermal ASCs injection can notably eliminate pigmentation in a guinea pig photoaging pigmentation model. This may be related to the fact that bFGF secreted by ASCs lowers MC1R and alpha-MSH levels, blocks the cAMP signalling pathway, and inhibits melanin synthesis. This finding may present new options for treating photoaging pigmentation.Level of Evidence: N/A.

Abstract
Skin is the outmost layer of human and sustains most of the external UVB irradiation, which possibly causes the skin photoaging. As a natural antioxidant, marine natural products have been paid more and more attention to their positive effects on photoaging. 6,6'-bieckol is a phlorotanin isolated from Ecklonia cava, while its antiphotoaging bioactivity and mechanism have not been clear yet. This study proves that 6,6'-bieckol enhances cells viability and decreases the level of ROS in UVB-induced human immortalized keratinocytes (HaCaT) cells. It also resulted in significant downregulation of matrix metalloproteinases (MMPs), p-c-Fos, phosphorylated JNK, p38, IκB and p65. In addition, molecular docking also showed that 6,6'-bieckol could bind to MMP-1, MMP-3 and MMP-9. Finally, it was proved that 6,6'-bieckol acts on MMPs through the MAPK/AP-1 and NF-κB pathways to reduce UVB-induced oxidative stress damage in HaCaT cells. Therefore, 6,6'-bieckol is a functional food and skin care ingredient with great potential in preventing photoaging.

Abstract
Ischemic stroke affects many people in the world, but the underlying mechanism is not completely understood. In this study, we investigated the effect of microRNA (miR)-31 on ischemic stroke. We also determined downstream signaling pathway of miR-31 in recovery of neurological function in ischemic stroke. Middle cerebral artery occlusion (MCAO) in mice was used to mimic human stroke. Foot fault test and mNSS were used to evaluate neurological deficits in mice after stroke. TTC staining in brain tissues was used for determining infarct volume. We extracted and identified extracellular vesicles (EVs) derived from adipose-derived stem cells (ADSCs) to study the impact of miR-31 and TRAF6 by miR-31 overexpression or TRAF6 knockdown on stroke recovery. Primary mouse neuron exposed to oxygen-glucose deprivation (OGD) was used to mimic neuronal ischemic injury. RT-qPCR and Western blot analysis were used for determination of mRNA and protein expression, respectively. MTT assay was used for studying cell survival. TUNEL staining was sued for neuron apoptosis. Starbase website and dual luciferase reporter gene assay were utilized to predicted and verify binding relationship between miR-31 and TRAF6. Neurological functions were improved by miR-31 from ADSC-derived EVs, as suggested by improved foot fault and mNSS. miR-31 from ADSC-derived EVs also reduced infarct volume and neuronal cell apoptosis after stroke in mice. Similarly, in neuronal cell culture, miR-31 from ADSC-derived EVs reduced the expression of apoptosis-related factors cleaved caspase-3 and Bax, increased the survival, and reduced apoptosis of neuronal cells after OGD. miR-31 was found to downregulate the expression of TRAF6 by binding to the 3'-untranslated region (3'-UTR) of TRAF6, which in turn upregulated IRF5 expression. Increased expression of IRF5 led to increased neuron apoptosis after OGD. In conclusion, miR-31 from ADSC-derived EVs can downregulate expression of TRAF6 and IRF5, leading to reduced neuronal damage induced by ischemic stroke.

Abstract
Photoaging is mainly induced by continuous exposure to sun light, causing multiple unwanted skin characters and accelerating skin aging. Adipose-derived stem cells(ADSCs) are promising in supporting skin repair because of their significant antioxidant capacity and strong proliferation, differentiation, and migration ability, as well as their enriched secretome containing various growth factors and cytokines. The identification of the mechanisms by which ADSCs perform these functions for photoaging has great potential to explore therapeutic applications and combat skin aging. We also review the basic mechanisms of UV-induced skin aging and recent improvement in pre-clinical applications of ADSCs associated with photoaging. Results showed that ADSCs are potential to address photoaging problem and might treat skin cancer. Compared with ADSCs alone, the secretome-based approaches and different preconditionings of ADSCs are more promising to overcome the current limitations and enhance the anti-photoaging capacity.

Abstract
Currently, many extracts from natural sources are added to cosmetic products for reducing facial aging and wrinkles. This study investigated the antiwrinkle activity of enriched extract of Isatidis Folium used for a novel antiwrinkle cream product. The result demonstrated that this enriched extract has excellent antiwrinkle activity by significantly inhibiting mRNA expression of matrix metalloproteinase-1, matrix metalloproteinase-3, and pro-inflammatory cytokines IL-1β and upregulating the mRNA expression of IL-4 and procollagen. Additionally, to implement effective quality control of the entire manufacturing process of antiwrinkle cream products based on the enriched extract of Isatidis Folium, the main chemical constituents of the enriched extract of Isatidis Folium was evaluated by high-performance liquid chromatography-photodiode array-tandem mass spectrometry (HPLC-PDA-ESI-MS/MS), five constituents were undisputedly confirmed. An HPLC-UV method in 15-min analysis time for quality assessment of the entire manufacturing process of antiwrinkle cream products was proposed and validated. The optimal conditions for extracting TMCA (3,4,5-trimethoxycinnamic acid) from the developed antiwrinkle cream products were determined using response surface methodology based on central composite design. The established HPLC method and optimal extract condition are suitable for routinely analyzing this novel antiwrinkle cream product.
