Project description:To examine the effects of recombinant granulin on human mammary stromal fibroblasts, we cultured normal human mammary fibroblasts in the presence of recombinant human granulin (1ug/ml) or PBS every 24h for 6 days. We cultured normal human mammary fibroblasts in the presence human granulin (1ug/ml) or PBS control every 24h for 6 days. The analysis showen are for 3 control (control) and 3 granulin-treated (PGRN) fibrobast cultures.
Project description:To examine the effects of recombinant granulin on human mammary stromal fibroblasts, we cultured immortalized GFP+ normal human mammary fibroblasts in the presence of recombinant human granulin (1ug/ml) or PBS every 24h for 6 days. To generate GRN-independent CAFs, we injected immortalized GFP+ human mammary fibroblasts, MCF7Ras human breast carcinoma cells, and 20% Matrigel subcutaneously into nude mice. Tumors were allowed to form for a period of 45 days. GFP+ fibroblasts were isolated from tumors by mincing the tumors, dissociating, and culturing in the presence of 1 ug/ml puromycin for ~3-4 weeks. CAF purity was confirmed by ensuring that 100% of the population was GFP-positive.

Project description:Gene expression profiling of immortalized human mesenchymal stem cells with hTERT/E6/E7 transfected MSCs. hTERT may change gene expression in MSCs. Goal was to determine the gene expressions of immortalized MSCs.
Project description:Transcriptional profiling of human mesenchymal stem cells comparing normoxic MSCs cells with hypoxic MSCs cells. Hypoxia may inhibit senescence of MSCs during expansion. Goal was to determine the effects of hypoxia on global MSCs gene expression.
Project description:To understand the molecular mechanisms that underpin pro-tumourigenic functions of cancer-associated fibroblasts (CAFs) we compared the proteome, acetylome, phosphoproteome of human immortalised breast cancer CAFs with those of the normal mammary fibroblasts that they were generated from. Based on the results obtained, we have also analysed proteome changes when CAFs were treated with the P300/CBP inhibitor c646.
