DRG-CSC co-culture tissue engineered model, CSCs monoculture model and DRG monoculture model

ABSTRACT: In this study, we constructed a tissue-engineered DRG-CSC (corneal stromal cells) co-cultured model (DS model), a CSC monoculture model (S model), and a DRG monoculture model (D model). Chicken DRGs were extracted from E7-E10 chicken embryo. Human CSCs were extracted in stromal lenticules from small incision lenticule extraction (SMILE). Transcriptional profiling of DRG in the DS model (DS-D), DRG in the D model(D-D), CSCs in the DS model (DS-S), CSCs in the S model (S-S) was analyzed. After 7 days of culture, RNA of each group was extracted.

A Phase I/II Study of Active Immunotherapy With Cancer Stem Cells Vaccine for Colorectal Cancer

Project description:Most studies of cancer stem cells (CSC) involve the inoculation of cells from human tumors into immunosuppressed mice, preventing an assessment on the immunologic interactions and effects of CSCs. In this study, the investigators examined the vaccination effects produced by CSC-enriched populations from histologically distinct murine tumors after their inoculation into different syngeneic immunocompetent hosts. Enriched CSCs were immunogenic and more effective as an antigen source than unselected tumor cells in inducing protective antitumor immunity.Immune sera from CSC-vaccinated hosts contained high levels of IgG which bound to CSCs, resulting in CSC lysis in the presence of complement.CTLs generated from peripheral blood mononuclear cells or splenocytes harvested from CSC-vaccinated hosts were capable of killing CSCs in vitro. Mechanistic investigations established that CSC-primed antibodies and T cells were capable of selective targeting CSCs and conferring anti-tumor immunity.

Expression profiling of DRG from L5 spinal nerve ligation model of neuropathic pain in the rat

Project description:DRG samples were extracted at 28 and 50 days from L5 spinal nerve ligated rats and sham operated rats. Samples were pooled for each time point per group and hybridised to duplicate to RG_u34 genchips (A, B and C chips). Keywords: Disease state analysis

Gene expression changes in a breast cancer stem cell model.

Project description:Epithelial to mesenchymal transition (EMT) is activated during cancer invasion and metastasis, enriches for cancer stem cells (CSCs), and contributes to therapeutic resistance and disease recurrence. The epithelial cell line MCF7, can be induced to undergo EMT with the induction of PKC by PMA. 5-10% of the resulting cells have a CSC phenotype. This study looks at the transcriptome of these cells and how it differs from cells with a non-CSC phenotype.

Mouse DRG RNA-Seq

Project description:Multiple myeloma (MM) is a neoplasia of B plasma cells that often induces bone pain. However, the mechanisms underlying myeloma-induced bone (MIBP) pain are mostly unknown. Using a localized MM mouse model, we investigated MM induced gene expression changes in the dorsal root ganglia (DRG) innervating the MM-bearing bone and found alterations in pathways associated with cell cycle, immune response and neuronal signalling. The MM transcriptional signature was consistent with metastatic MM infiltration to the DRG, a never-before described feature of the disease that we further demonstrated histologically. In the DRG, MM cells caused loss of vascularization and neuronal injury, which may contribute to late-stage MIBP.

Human myocardial ischemia/reperfusion injury model to study cardiac stem cells activation and regeneration mechanisms

Project description:The importance of regenerative potential of cardiac stem/progenitor cells (CSCs) after acute myocardial infarction (AMI) has been emphasized in the last decade. Several studies have demonstrated that this cell population has a relevant role in myocardial repair, supported by the establishment of a paracrine cross-talk between CSCs and the injured tissue. However, the majority of current in vitro strategies to study these cells fails to include important modulators of CSC activity, such as the paracrine effect of cardiomyocytes (CMs) and the physicochemical changes occurring in tissue during Ischemia/Reperfusion (I/R) injury. In this work, we established the first human in vitro heterotypic model of myocardial I/R injury with human CSCs (hCSCs) and human induced pluripotent cell-derived cardiomyocytes (hiPSC-CMs) using transwell inserts. hCSCs response to I/R was characterized using advanced whole proteomic mass spectrometry-based tools that allowed us to propose new pathways in hCSCs regenerative process, including: cell cycle regulation inhibition, proliferation through EGF signaling, gluthathione-mediated reactive oxygen species detoxification, and signaling through several paracrine growth factors. The model established in this work contributes with new insights regarding hCSC biology in response to AMI and provides an important tool to study and modulate molecular mechanisms involved in the regenerative potential of CSCs.

Transcription profiling of wild type dorsal root ganglia (DRG) taken from mice 10-12 weeks, DRG taken from NT-4 -/- mice of 4-5 weeks, NT-4 -/- mice of 12 weeks

Project description:Gene expression profiling was carried out to compare labeled cRNA derived from 3 experimental groups. Group 1 was mRNA extracted from wild type dorsal root ganglia (DRG) taken from mice 10-12 weeks of age, Group 2 was mRNA extracted from DRG taken from NT-4 -/- mice of 4-5 weeks of age. Group 3 was mRNA extracted from DRGs taken from NT-4 -/- mice of 12 weeks of age. In all cases mRNA was extracted from 6-10 mice per group. The experiment was carried out a total of three times.

Mouse DRG incision injury versus sham_DIA-MS

Project description:Acute pain after surgery is still managed insufficiently. One major need is, therefore, the identification of new targets specifically relevant for postoperative pain to develop effective and non-addictive analgesics. To this end, we have used the plantar incision model in male mice and DIA-MS to reveal unprecedented insights into proteome dynamics in dorsal root ganglia (DRG) 24 hours after incision.

Expression profiles of CD24-/CD44+/ESA+ population in MDA-MB-231 and its highly metastatic variants.

Project description:Breast cancer is a curable disease if it is diagnosed at an early stage. However, only little options are left once the tumor is metastasized to distant organs, and more than 90% of breast cancer death is attributed to metastatic disease. The process of metastasis is highly complex and involves many steps for successful colonization of tumor cells at a target organ. According to the cancer stem cell (CSC) theory, which still remains a hypothesis, these metastatic cells must have stem cell-like capability for their self-renewal in addition to their invasive ability. Therefore, it has been predicted that a “metastatic stem cell”, which is distinct from a cancer stem cell, must exist in the primary tumor mass. To identify genes that are involved in metastasis of CSCs, we isolated CSC populations from a well-established model cell line of breast cancer, MDA-MB231, and that of highly metastatic variants, 231BoM-1833 and 231BrM-2a, using CD24, CD44 and EpCAM (ESA), which have been identified as surface markers for CSCs in breast cancers. Overall yield of CSCs from these cells ranged from 2% to 4%. We then performed global expression profile analysis for these CSCs using the Affymetrix Human Gene 1.0ST array. CSC populations (CD24-/CD44+/ESA+) from MDA-MB231, 231BoM-1833 and 231BrM-2a were isolated by magnetic-activated cell sorting (MACS) using specific antibodies to these surface markers. The total RNA was isolated from the CSC populations using the RNeasy RNA isolation kit (Qiagen). The RNA was then converted to cDNA and they were hybridized to the Human Gene 1.0ST chip (Affymetrix). The data was normalized using the RMA algorithm of the Expression Console software (Affymetrix). A comparison of transcriptional profiles was then performed in CSCs of highly metastatic cell lines (231BoM-1833 and 231BrM-2a) compared to the CSCs of MDA-MB-231.
