Affymetrix Murine Genome U74A Version 2 Array (mgu74av2)
Description
Succinate semialdehyde dehydrogenase (SSADH) deficiency is a rare autosomal recessive disorder effecting approximately 350 people around the world. Patients suffering from SSADH deficiency experience language acquisition failure, memory deficiencies, autism, increased aggressive behaviors, and seizures. There is a chemical buildup of both gamma-aminobutyric acid (GABA) and gamma-hydroxybutyric acid (GHB) in the neurological system of these patients. The Aldh5a1-/- knock out mouse model of SSADH deficiency shows the same chemical imbalances as the human disease, with additional fatal tonic-clonic seizures at three weeks of age. The elucidation of seizure causing pathways will facilitate treatment of seizure phenotypes in diseases with related epilepsy.

Description
The immortalized human urothelial cell line, UROtsa, was transformed in six parallel cultures with continual passaging in1 M Cd+2 until the cells were able to attain the ability to form colonies in soft agar and subcutaneous tumors in nude mice. The gene expression profiles between cadmium-transformed and control samples were compared and the differentially expressed genes were identified.

- Affymetrix Human Gene 1.1 ST Array (hugene11st)
Description
Mesenchymal stromal cells (MSCs) sense and modulate inflammation and represent potential clinical treatment for immune disorders. However, many details of the bidirectional interaction between MSCs and the innate immune comaprtment are still unsolved. Here we describe an unconventional but functional interaction between pro-inflammatory classically activated macrophages (M1M) and MSCs, with CD54 playing a central role. CD54 was upregulated and enriched specifically at the contact area between M1M and MSCs. Moreover, the specific interaction induced calcium signaling and increased the immunosuppressive capacities of MSCs dependent on CD54 mediation. Our data demonstrate that MSCs can detect an inflammatory microenvironment via a direct and physical interaction with innate immune cells. This finding opens new perspectives for MSC-based cell therapy.

Description
Bone-marrow mesenchymal stem cells (MSCs) are plastic adherent cells that can differentiate into various tissue lineages, including osteoblasts, adipocytes and chondrocytes. However, this progenitor property is not shared by all cells within the MSC population. In addition, MSCs vary in their proliferation capacities and expression of markers. Because of heterogeneity of CD146 expression in the MSC population, we compared CD146-/Low and CD146High cells under clonal and non-clonal (sorted MSCs) conditions to determine whether this expression is associated with specific functions. CD146-/Low and CD146High MSCs did not differ in colony-forming unit-fibroblast number, osteogenic and adipogenic differentiation or in vitro hematopoietic supportive activity. However, CD146-/Low clones proliferated slightly but significantly faster than did CD146High clones. In addition, a strong expression of CD146 molecule was associated with a commitment towards a vascular smooth muscle cell lineage with upregulation of calponin-1 expression. Thus, within a bone-marrow MSC population, certain subpopulations characterized by high expression of CD146, are committed toward a vascular smooth muscle cell lineage.

Data accompaning to van Gurp et al. Development 2019. single-cell sequencing of the developing mouse pancreas followed by Seurat analysis to discover genes important for alpha and beta cell differentiation. Overall design: Single-cells from mouse embryonic pancreas at E12.5, E13.5, E14.5, E15.5 and E18.5 were isolated and enriched for MIP-GFP and sorted into 384-well plates. Afterwards, SORT-seq was performed and single-cell transcriptomics profiles were obtained.

Description
Macrophage aging is pathogenic in numerous diseases, including age-related macular degeneration. Although prior studies have explored the functional consequences of macrophage aging, less is known about its cellular basis or what defines the transition from physiologic aging to disease. The purpose of this experiment was to characterize the transcriptomic changes associated with macrophage aging.

Description
We have studied the plasma membrane protein phenotype of human culture-amplified and native Bone Marrow Mesenchymal Stem Cells (BM MSCs). We have found, using microarrays and flow cytometry, that cultured cells express specifically 113 transcripts and 17 proteins that were not detected in hematopoietic cells. These antigens define a lineage-homogenous cell population of mesenchymal cells, clearly distinct from the hematopoietic lineages, and distinguishable from other cultured skeletal mesenchymal cells (periosteal cells and synovial fibroblasts). Among the specific membrane proteins present on cultured MSCs, 9 allowed the isolation from BM mononuclear cells of a minute population of native MSCs. The enrichment in Colony-Forming Units-Fibroblasts was low for CD49b, CD90 and CD105, but high for CD73, CD130, CD146, CD200 and integrin alphaV/beta5. Additionally, the expression of CD73, CD146 and CD200 was down-regulated in differentiated cells. The new marker CD200, because of its specificity and immunomodulatory properties, deserves further in depth studies.
