Project description:Tumors can occur in many sites in the body, but how tissues at different anatomical sites affect tumor microenvironments and their subsequent response to therapy is not known. Here we show that different tissues can cause the same tumor to develop fundamentally different microenvironments resulting in dramatic changes in responses to immunotherapy. Whereas established subcutaneous tumors could be eradicated in the majority of mice using a combination of three agonist antibodies, tumors in visceral organs responded much less. Orthotopic kidney tumors had a microenvironment with a higher frequency of alternatively-activated macrophages and their associated molecules. Neutralizing the CCL2 chemokine or IL-13 cytokine, important in macrophage biology led to a greatly improved therapeutic effect. Importantly, a significantly reduced therapeutic response of subcutaneous tumors was observed when visceral tumors were simultaneously present in the same mice. In this study we sought to compare gene expression of mouse renal cell carcinoma cells growing in the kidney to cells growing subcutaneously. Renca is a renal cell carcinoma cell line (Murphy and Hrushesky, 1973). To produce subcutaneous tumors, mice received 2 x 10^5 Renca. Orthotopic tumors were established by first surgically isolating the organ and then injecting 2 x 10^5 Renca cells intrakidney (IK) into the outer cortex of the kidney in 20 ul of PBS. Tumors were removed from mice 12 days after implantation, when approximately 20-30 mm2. Tumors were snap frozen on liquid nitrogen prior to processing for total RNA followed by analysis on Mouse Gene 1.0 chips. Kidney Renca tumors were excised from 3 BALB/c mice and subcutaneous Renca tumors were excised from another 3 BALB/c mice. cDNA was prepared and hybridized to Mouse Gene 1.0 ST chips.

Project description:Owing to the risk of insertional mutagenesis, viral transduction has been increasingly replaced by nonviral methods to generate induced pluripotent stem (iPS) cells. We report the use of ‘minicircle’ DNA, a vector type that is free of bacterial DNA and capable of high expression in cells. Here we use a single minicircle vector to generate transgene-free iPSCs from adult human adipose stem cells. (Note: Our Nature Methods publication included analysis of array data from GSM374067 and GSM374068 in conjunction with this series).

Project description:To understand the invasive microenvironment of head and neck squamous cell carcinomas (HNSCCs) at a single-cell resolution, we performed single-cell RNA-sequencing (scRNA-seq) using cells derived from calvaria of tumor-free control mice and tumor-excised calvarial tissues from pre-invasive stage（scratch-negative）and invasive stage（scratch-positive）groups 1 week after the implantation of C57BL/6-derived HNSCC cell line HNM007 cells.

Project description:Mouse extended pluripotent stem (EPS) cells have demonstrated significant potential for generating embryo models in vitro. However, their limited capacity for extraembryonic trophoblast development has hindered their use in constructing whole embryo models, particularly post-implantation embryoids. Here, we establish a stepwise induction protocol to generate trophectoderm-like cells from mouse EPS cells. These cells retain trophectoderm-specific transcriptomic features and can differentiate into trophoblast lineages in vivo. Moreover, combining these trophectoderm-like cells with EPS cell-derived primitive endoderm/epiblast bilineage structures enabled the robust generation of post-implantation embryoids in a transgene-free manner. EPS-derived embryoids recapitulate key developmental events of post-implantation mouse embryos, including the formation of the pro-amniotic cavity, anterior-posterior axis, primitive streak, gastrulation, and complex extraembryonic tissues. Notably, single-cell transcriptomic analysis revealed a high degree of transcriptional similarity between EPS-derived embryoids at day 6 and natural E7.5 mouse embryos. Our study presents a novel platform for modeling post-implantation mouse embryogenesis in vitro.

Project description:Human endometrial epithelium (EE) is composed of a multitude of proteins, amongst which those localized on the plasma membrane (plasma membrane proteins-PMPs) are of critical relevance in early stages of implantation. Evidences support the key role of few PMPs in implantation. However, many remain unidentified, as efforts have not been made till date to generate the plasma membrane proteome of human EE cells, using a gel-free approach. This study presents a protein catalogue of the PMP enriched fraction of Ishikawa cell line; often used as an in vitro model for embryo-adhesive EE. Liquid Chromatography with tandem mass spectrometry identified 3598 proteins. Of these, 1963 proteins were annotated for their membrane localization. Of 1963 proteins, 1321 were found to have transmembrane domain and 43 proteins had GPI anchor. Extensive data mining revealed endometrial expression of 943 proteins reported in human and/or rodents. Further, quantitative alterations were observed in the plasma membrane proteome on perturbation of intracellular trafficking. Silencing of Rab11a (known for its role in plasma membrane organization) expression caused alteration in the abundance of 74 proteins. Caveolin-1 and EpCAM levels were reduced whereas Rab4a abundance increased in the PMP extracts of Rab11a-deficient cells, compared to control cells. Briefly, the study reports the identity of several novel plasma membrane-localized proteins. A major spin-off of the study is the identification of novel proteins trafficked by Rab11a to the plasma membrane. Targeted analysis of novel PMPs may reveal their specific roles in endometrial receptivity and implantation.
