Description
Growth restriction, craniofacial dysmorphology and central nervous system defects are the main diagnostic features of fetal alcohol syndrome. Studies in humans and mice have reported that the growth restriction can be prenatal and/or postnatal, but the underlying mechanisms remain unknown. We recently described a mouse model of moderate gestational ethanol exposure that produces measurable phenotypes in line with fetal alcohol syndrome, e.g. craniofacial changes and growth restriction in adolescent mice. Here we further characterize the growth restriction phenotype by measuring body weight at gestational day 16.5, cross-fostering from birth to weaning, and extending our observations into adulthood. Furthermore, in an attempt to unravel the molecular events contributing to the growth phenotype, we have compared gene expression patterns in the liver and kidney of non-fostered ethanol-exposed and control mice at postnatal day 28. We find that the ethanol-induced growth phenotype is not detectable prior to birth, but is present at weaning, even in mice that have been cross-fostered to unexposed dams. This suggests a postnatal growth restriction phenotype that is not due to deficient postpartum care by dams that drank ethanol, but rather a physiological result of ethanol exposure in utero. We also find that, despite some catch-up growth after five weeks of age, the effect extends into adulthood, consistent with longitudinal studies in humans. Genome-wide gene expression analysis revealed interesting ethanol-induced changes in the liver, including genes involved in the metabolism of exogenous and endogenous compounds, iron homeostasis and lipid metabolism.

Description
Human adipose stem cells (ASCs) have been shown, in pre-clinical studies, to have therapeutic applicability in diverse fields, but a standard expansion method for clinical applications remains yet to be established. Isolated ASCs are typically expanded in medium containing fetal bovine serum (FBS). However, sera and other animal-derived culture reagents stage numerous safety issues in clinical therapy, including possible infections and severe immune reactions. By expanding the ASCs in medium containing human serum (HS), the problem can be eliminated.
Publication Title
Differential gene expression in adipose stem cells cultured in allogeneic human serum versus fetal bovine serum.

Description
Respiratory viral infections follow an unpredictable clinical course in young children ranging from a common cold to respiratory failure. The transition from mild to severe disease occurs rapidly and is difficult to predict. The pathophysiology underlying disease severity has remained elusive. There is an urgent need to better understand the immune response in this disease to come up with biomarkers that may aid clinical decision making. In a prospective study, flow cytometric and genome-wide gene expression analyses were performed on blood samples of 26 children with a diagnosis of severe, moderate or mild Respiratory Syncytial Virus (RSV) infection. Differentially expressed genes were validated using Q-PCR in a second cohort of 80 children during three consecutive winter seasons. FACS analyses were also performed in the second cohort and on recovery samples of severe cases in the first cohort. Severe RSV infection was associated with a transient but marked decrease in CD4+ T, CD8+ T, and NK cells in peripheral blood. Gene expression analyses in both cohorts identified Olfactomedin4 (OLFM4) as a fully discriminative marker between children with mild and severe RSV infection, giving a PAM cross-validation error of 0%. Patients with an OLFM4 gene expression level above -7.5 were 6 times more likely to develop severe disease, after correction for age at hospitalization and gestational age. In conclusion, by combining genome-wide expression profiling of blood cell subsets with clinically well-annotated samples, OLFM4 was identified as a biomarker for severity of pediatric RSV infection.
