Project description:Gene expression profile of treatment with FABP4 or FABP5 in ADSC and 233A cells was examined. ADSC or 233A cells were treated with and without 1 µM recombinant FABP4 or FABP5.
Project description:Analysis of 20S proteasome in various tissue, adipose derived stem cells(ADSC) or HeLa cells treated with interferon-gamma. This results are compared with LC-SRM results obtained on the same samples. Global proteomics on ADSC amplified in 5% or 20% O2.
Project description:Transcriptional activity was identified in all categories of genes expressed by ADSC, including collagens, ECM and basement membrane constituents, adhesion molecules involved in cell-cell and cell-matrix interactions, and proteases involved in degradation of the ECM and their inhibitors. Importantly, it was observed that ADSC synthesize and secrete all three collagen VI chains, suggesting suitability of ADSC for collagen VI congenital muscular dytrophy treatment. We developed a procedure for isolation of human stem cells from adipose layer of neonatal foreskin skin. The adipose-derived stem cells (ADSC) were examined for expression of extracellular matrix (ECM) and related genes using gene expression array analysis.
Project description:Adipose-derived stem cells (ADSCs) demonstrated potential in tissue repair, and their extracellular vesicles (ADSC-EVs) show more safety in clinical translation. This study aims to investigate the protective effects of ADSC-EVs on rat POI models and to explore the potential therapeutic mechanisms. Whole-transcriptome sequencing of ADSC-EVs were performed to identify bioactive molecules.
Project description:The aim of this study is to characterize how the extracellular matrix secreted by adipose-derived stem cells (ADSC) during osteogenesis affects the differentiation process. Specifically, ADSC undergo osteogenesis by following similar maturational phases as bone marrow-derived stem cells. However, it is unclear how the differentiation process is the same and how it differs. We first focused on ADSC behavior by analyzing whole transcriptome changes in response to osteogenic media supplements added into the tissue culture medium. We then developed osteogenic differentiation expression profiles for the ADSC and identify key genes and pathways that serve as an osteogenesis signature. This expression signature acted as a template for comparison of how extracellular matrix (ECM) affected ADSC differentiation. We studied ADSC induced to differentiate on ECM isolated from day 16 in the differentiation process (the midpoint in osteogenesis) as well as ECM from day 11 in the differentiation process. Ultimately, we aim to dissect the relationship between cells grown on ECM as an in vitro growth substrate and cells grown on tissue culture plastic; both in the presence of osteogenic supplements. This study, will allow us to determine the extent to which ECM affects the differentiation process.
Project description:Diabetes is a significant global chronic disease characterized by elevated mortality and disability rates due to persistent infections resulting from refractory wounds. Currently, effective treatment strategies are lacking. Adipose-derived stem cell extracellular vesicles (ADSC-EVs) have been shown to promote skin wound healing; however, their clinical application is impeded by low yield and heterogeneity. We successfully isolated high-yield extruded nanovesicles from adipose stem cells (ADSC-NVs), achieving yields over 30 times greater than those of ADSC-EVs while maintaining similar morphological characteristics. Our findings indicate that ADSC-NVs exhibit a dose-dependent enhancement of proliferation and migration in primary human dermal fibroblasts (HDF) in vitro. Notably, the expression levels of proliferating cell nuclear antigen (PCNA), collagen type I (COL-I), and collagen type III (COL-III) were significantly upregulated in HDF following treatment with ADSC-NVs. RNA-seq analysis further revealed that the differentially expressed genes (DEGs) shared between the ADSC-NVs group and control group were predominantly enriched in the Wnt signaling pathway. Consistently, ADSC-NVs facilitate efficient diabetic wound healing while promoting proliferation and inhibiting inflammation via the Wnt/beta-catenin signaling pathway. In summary, high-yield ADSC-NVs represent a promising alternative to ADSC-EVs for enhancing diabetic wound healing, providing novel insights and methodologies for improving therapeutic outcomes.
Project description:Alveolar macrophages (AMs) are crucial for pulmonary defense and immune regulation. Exosomes from adipose-derived mesenchymal stem cells (ADSC-Exos) have emerged as a promising therapy for inflammatory lung diseases by modulating immune responses. This study investigates the ability of ADSC-Exos to alleviate inflammation in acute lunag injury (ALI), a condition often triggered by sepsis and characterized by lung permeability and respiratory failure.
Project description:We have used RNA-sequencing on six different proliferating cell lines consisting of normal human dermal fibroblasts (NHDF), normal human epidermal keratinocytes (NHEK), pericytes (PC), human microvADSCular blood endothelial cells (HMEC), lymphatic endothelial cells (LEC) and adipose derived stem cells (ADSC), subjected to different doses of radiotherapy.
Project description:The aim of this study was to elucidate the role of the adipose tissue-derived stem cell (ADSC) secretome on NK cell activity. To elucidate the molecular mechanisms involved, we used mRNA sequencing to profile the transcriptional expression of human blood NK cells from 6 donors.
