Description
Interstitial cells of Cajal (ICC) are electrical pacemakers and mediators of neuromuscular neurotransmission in the gastrointestinal tract. Studies in organotypic cultures of intact gastric muscular wall tissues identified Kit(low)Cd44(+)Cd34(+)Insr(+)Igf1r(+) cells as local ICC progenitors (Lorincz et al., Gastroenterology 2008;134:1083-1093). Subsequently, conditionally immortalized Kit(low)Cd34(+) cells were isolated by immunomagnetic and fluorescent cell sorting and serial cloning from the gastric muscular wall of homozygous, 14-day-old H-2Kb-tsA58 mice and shown to share other phenotypic characteristics with in-situ ICC precursors (2xSCS70 cells; Bardsley et al., Gastroenterology 2010;139:942-952). 2xSCS70 cells were also found to express the ICC marker Ano1, be able to extensively self-renew in the absence of the SV40 tsA58-TAg when cultured in NeuroCult Neural Stem Cell Proliferation Medium (NSCPM; STEMCELL Technologies) and differentiate into Kit(+) ICC both in vitro and in vivo. Wild-type cells with Kit(low)Ano1(+)Cd44(+)Cd34(+)Insr(+)Igf1r(+) phenotype (2xSCS2F10 cells) were prospectively isolated from primary cultures of dissociated gastric muscular wall tissues from 7-day-old C57BL/6J mice by serial cloning following 150-day expansion in NSCPM containing 5% cell-free chick embryo extract (CEE; Accurate Chemical). Long-term culturing of both cell lines was associated with further decline in Kit expression while expression of Ano1 and other markers of ICC precursors was maintained. Following spontaneous transformation, both 2xSCS70 and 2xSCS2F10 cells grafted into nude mice gave rise to tumors containing Kit(+)cells and otherwise resembling gastrointestinal stromal tumors (GIST), which originate from the ICC lineage (Bardsley et al., Gastroenterology 2010;139:942-952).

We performed miRNA and mRNA profiling at postnatal day 14 and day 29 to compare hyperoxia-induced bronchopulmonary dysplasia and wild type. We built potential miRNA-mRNA interaction networks specific to brochopulmonary dysplasia.

Description
Primordial genomic challenge compromises embryonic development and survival, and surveillance of deployed transcriptional programs may provide an early opportunity to forecast phenotype abnormalities. Here, comparisons between wild-type and calreticulin-ablated embryonic stem cells revealed transcriptome shifts precipitated by calreticulin loss. Bioinformatic analysis identified down and up-regulation in 1187 and 418 genes, respectively. Cardiovascular development precedes other organogenic programs, and examination of cardiogenic genes revealed a map of calreticulin-calibrated expression profiles that encompass the developmental regulators, Ccnd1, Ccnd2 and Notch1. Interrogation of primary function in the resolved network forecasted abnormalities during myocardial development. Whole embryo magnetic resonance imaging, verified by pathoanatomical analysis, diagnosed prominent ventricular septal defect. Correlation clustering and network resolution of probesets associated with protein folding/chaperoning and calcium handling demonstrated 14 and 19 genes, respectively, modulated by calreticulin deficiency. Calreticulin deletion provoked ontological re-prioritization of gene expression, molecular transport and protein trafficking that translated into multiple subcellular functional outcomes. Individual stem cell-derived cardiomyocytes lacking calreticulin demonstrated a disorganized contractile apparatus with mitochondrial paucity and architectural aberrations. Thus, bioinformatic deconvolution of primordial embryonic stem cell transcriptomes enables predictive phenotyping of defective developmental networks that coalesce from complex systems biology hierarchies.

Description
A dual biomarker signature extracted a stage-specific cytotype according to cell surface expression of CXCR4/FLK-1 after 5 days of spontaneous differentiation from pluripotent stem cells. Genome-wide microarray analysis revealed a high degree of similarity between CXCR4+/FLK-1+ and CXCR4-/FLK-1- subpopulations at day 5, yet the divergent gene expression profile represents more than 700 unique transcripts. Functional analysis of the 294 up-regulated and 440 down-regulated transcripts that distinguished CXCR4+/Flk-1+ from CXCR4-/Flk-1- subpopulations identified an overt ontologic prioritization of Cardiovascular Development-IPA 7.0, 2009.Thus, a biomarker-selected subpopulation from spontaneously differentiated pluripotent stem cells identifies a pool of genes that non-stochastically integrate into a blueprint providing instructions for cardiac lineage-specification.
