Description
The thymus is extremely sensitive to damage but also has a remarkable ability to repair itself. However, the mechanisms underlying this endogenous regeneration remain poorly understood and this capacity diminishes considerably with age. To identify alternate regeneration pathways in the thymus, we performed an unbiased transcriptome analysis of the non-hematopoietic (CD45-) stromal cell compartment of the thymus, which is less sensitive to thymic damage compared to the CD45+ hematopoietic compartment.
Publication Title
Production of BMP4 by endothelial cells is crucial for endogenous thymic regeneration.

Description
This data series was used for two separate studies. The initial study was aimed to idenify expression changes brought about by the Cecr2Gt45Bic mutation during neural closure. The study included two different strains, BALB/cCrl in which Cecr2GT45Bic shows a neural tube defect phenotype and FVB/N in which Cecr2Gt45Bic does not manifest neural closure defects. The second was to idenify strain specific expression differences present during neural closure of the mouse embryo between BALB/cCrl and FVB/N in order to identify candidate modifiers of the Cecr2Gt45Bic neural tube defect. Relevant abstracts are included below.

Background and Aims: In the interleukin-10-deficient (Il10-/-) mouse model of IBD, 10 quantitative trait loci (QTL) have been shown to be associated with colitis susceptibility by linkage analyses on experimental crosses of highly susceptible C3H/HeJBir (C3Bir)-Il10-/- and partially resistant C57BL/6J (B6)-Il10-/- mice. The strongest locus (C3Bir-derived cytokine deficiency-induced colitis susceptibility [Cdcs]1 on Chromosome [Chr] 3) controlled multiple colitogenic subphenotypes and contributed the vast majority to the phenotypic variance in cecum and colon. This was demonstrated by interval-specific Chr 3 congenic mice wherein defined regions of Cdcs1 from C3Bir or B6 were bred into the IL-10-deficient reciprocal background and altered the susceptible or resistant phenotype. Furthermore, this locus likely acts by inducing innate hypo- and adaptive hyperresponsiveness, associated with impaired NFB responses of macrophages. The aim of the present study was to dissect the complexity of Cdcs1 by further development and characterization of reciprocal Cdcs1 congenic strains and to identify potential candidate genes in the congenic interval. Material and Methods: In total, 15 reciprocal congenic strains were generated from Il10-/- mice of either C3H/HeJBir or C57BL/6J backgrounds by 10 cycles of backcrossing. Colitis activity was monitored by histological grading. Candidate genes were identified by fine mapping of congenic intervals, sequencing, microarray analysis and a high-throughput real-time RT-PCR approach using bone marrow-derived macrophages. Results: Within the originally identified Cdcs1-interval, three independent regions were detected that likely contain susceptibility-determining genetic factors (Cdcs1.1, Cdcs1.2, and Cdcs1.3). Combining results of candidate gene approaches revealed Fcgr1, Cnn3, Larp7, and Alpk1 as highly attractive candidate genes with polymorphisms in coding or regulatory regions and expression differences between susceptible and resistant mouse strains. Conclusions: Subcongenic analysis of the major susceptibility locus Cdcs1 on mouse chromosome 3 revealed a complex genetic structure. Candidate gene approaches revealed attractive genes within the identified regions with homologs that are located in human susceptibility regions for IBD.

Down syndrome is the most common form of genetic mental retardation. How Trisomy 21 causes mental retardation remains unclear and its effects on adult neurogenesis have not been addressed. To gain insight into the mechanisms causing mental retardation we used microarrays to investigate gene expression differences between Ts1Cje (a mouse model of Down syndrome) and C57BL/6 littermate control neurospheres. The neurospheres were generated from neural stem cells and progenitors isolated from the lateral walls of the lateral ventricles from adult mice.

Description
Myelodysplastic syndrome (MDS) is considered a disease of hematopoietic stem cell (HSC) origin. To begin to unravel the molecular mechanisms underlying the deregulation of HSCs in MDS, we performed comparative gene expression profiling on Crebbp+/- and wild type HSCs. We chose to isolate HSCs from the fetal liver (FLHSC) because at this stage there were no differences in cell number between Crebbp+/- and wild type fetal livers, suggesting no overt hematopoietic differences. Thus, any change in gene expression found in Crebbp+/- FLHSCs is likely to reflect the initially compromised genetic program of HSC regulation, as opposed to that of Crebbp+/- HSCs in adult bone marrow, where secondary changes in gene expression may also occur as compensatory mechanisms for a compromised or failing hematopoietic system. We used day 14.5 post coitus FLHSC (Sca-1+,Lin-,AA4.1+,c-Kit++) from wild type (wt) and Crebbp heterozygous (ht) embryos to examine changes in gene expression before overt myelodysplastic disease manifestation.
