Gene expression in FIH-1 silenced human nucleus pulposus cells

ABSTRACT: To evaluate the effect of Hypoxia-inducible factor 1-alpha inhibitor (HIF-1) in nucleus pulposus (NP) cells, human NP cells were lentivirally transduced with either control or FIH-1 targeted shRNA. Gene expression changes between samples from control and FIH-1 silenced cells were evaluated using a microarray. Primary NP cells were isolated from human discs and grown in culture. Cells were transduced with either control or FIH-1 targeting shRNA constructs. Silencing of FIH-1 was confirmed for each set using qRT-PCR and Western blot. Total RNA from NP cells was used for RNA extraction and hybridization on the Affymetrix microarray. Control samples: C1, C2, and C3 and FIH-1-silenced samples: E1, E2, and E3.

Transcription profiling of human nucleus pulposus vs articular cartilage cell types

Project description:The aim of this study was threefold: Firstly, to carry out microarray hybridisations using human AC and NP cells to identify NP and AC specific markers. Secondly, to further investigate their ability to characterise adult derived stem cells differentiating towards an NP phenotype using an in vitro differentiation system and thirdly, in their application to compare the suitability of BMSC and ADRCs as a stem cell source for tissue engineering of the IVD. Using microarray technology we have identified several novel human AC and NP markers and have demonstrated that these markers are capable of identifying the differentiation of adult derived stem cells towards an NP rather than an AC phenotype. In addition these markers suggest that ADRCs provide a more suitable cell source for tissue engineering of the intervertebral disc.

Expression data from synovium, bone marrow and nucleus pulposus

Project description:Synovial and bone marrow mesenchymal stem cells after intradiscally injection show regenerative effects of nucleus pulposus. Microarray analyses of rats were performed to investigate the closeness of the gene profiles between the nucleus pulposus cells and the synovial or bone marrow mesenchymal stem cells. To investigate interaction between synovial mesenchymal stem cells and nucleus pulposus cells, human synovial mesenchymal stem cells and rat nucleus pulposus cells were co-cultured, and species specific microarray were performed. Synovium of knee joints, bone marrow and nucleus pulposus were harvested from rat or human, and cells were isolated for RNA extraction and hybridization on Affymetrix microarrays. To compare the gene profiles each other, isolated cells were mono-cultured respectively, and human synovial mesenchymal stem cells and rat nucleus pulposus cells were co-cultured.

Proteomic analysis of filaggrin insufficient keratinocytes and secreted exosomes.

Project description:Filaggrin (FLG) is a key structural protein expressed in epidermal keratinocytes. Mutations in the filaggrin gene (FLG) are strongly linked to atopic dermatitis (AD) and allergic inflammation occurring later in life at distant body locations in AD patients. Keratinocytes secrete exosomes, small, lipid-rich membrane vesicles to communicate with distant cells, including within the immune system. The FLG gene was silenced in the HaCaT keratinocyte cell line by shRNA delivered using a lentiviral vector. HaCaT cells transduced with scrambled shRNA were used as a control.

An Organ Culture System to Model Early Degenerative Changes of the Intervertebral Disc: II Profiling Global Gene Expression Changes

Project description:To mimic a degenerative insult, rat intervertebral discs were cultured in the presence of TNF-alpha, IL-1beta and serum limiting conditions. Gene expression analysis was performed using a microarray to identify differential gene expression between experimental and control groups. The discs were collected and the annulus fibrosus (AF) was separated from the nucleus pulposus (NP). Total RNA from NP was used for RNA extraction and hybridization on Affymetrix microarrays: Control group - Ctr-1, Ctr-2, Ctr-3, Ctr-4 and Experimental group-Exp-1, Exp-2, Exp-3, Exp-4.

Human iPS cell-derived cartilage spatially and functionally replaces nucleus pulposus

Project description:Single cell RNA sequencing (scRNA-seq) analysis identified notochordal nucleus pulposus (NP) cells and chondrocyte-like NP cells in NP. Cells in human induced pluripotent stem cell-derived cartilage (hiPS-Cart) corresponded to chondrocyte-like NP cells but not to notochordal NP cells. hiPS-Cart cells changed their profile after implantation into intervertebral disks of nude rats, differentiating into two lineages that are metabolically distinct from each other. However, post-implanted hiPS-Cart cells corresponded to chondrocyte-like NP cells only and did not develop into notochordal NP cells.
