9.9. Co-transplantation of mesenchymal stem cells improves spermatogonial stem cell transplantation efficiency in mice

P Kadam , E Ntemou , Y Baert , S Van Laere , D Van Saen , E Goossens

To read the full abstract: Stem Cell Res Ther. 2018 Nov 21; 9 (1):317Spermatogonial stem cell transplantation (SSCT) could become a fertility restoration tool for childhood cancer survivors. However, the colonization efficiency of transplanted spermatogonial stem cells (SSCs) in animal models is about 12%, and the effectiveness of this procedure needs to be improved before clinical imple...

1.3 Hypothalamic stem cells control ageing speed partly through exosomal miRNAs

Y Zhang , MS Kim , B Jia , J Yan , JP Zuniga-Hertz , C Han , D Cai

To read the full abstract: Nature 2017;548:52-57The central nervous system contributes to ageing. The hypothalamus seems to be particularly important in this process. Recent studies have demonstrated a link between ageing and a decrease of neurogenesis in the hippocampus and the subventricular zone of the lateral ventricle in the brain. Neural stem/progenitor cells (NSC) reside in those regions in ...

11.9 Neural correlates of familial obesity risk and overweight in adolescence

S Carnell , L Benson , KY Chang , Z Wang , Y Huo , A Geliebter , BS Peterson

To read the full abstract: NeuroImage 2017; 159: 236-247The results of this study suggest that, compared to adolescents with a low risk, lean adolescents with a high familial obesity risk show a weaker activation of neural systems subserving attentional self-regulation in response to food-denoting words. These same changes were found in overweight or obese adolescents. It is interestin...

VM Breinholt , PH Mygind , ED Christoffersen , Y Zhang , S Ota , R Will Charlton , D Viuff

In Brief: This phase 1 study in healthy adults assessed the safety and feasibility of transcon-CNP, a novel prodrug that releases native C-type natriuretic peptide (CNP). The novel drug was well tolerated and CNP remained in systemic circulation for >7 days following a single dose.Commentary: Achondroplasia is caused by autosomal activating mutation in the fibroblast growth factor receptor 3 gene (FGFR3) resulting in constitutive receptor ac...

J Clin Endocrinol Metab. 2020 Jun 1;105(6):dgaa131. doi: 10.1210/clinem/dgaa131. PMID: 32170311Genetic control of height has been widely explored using genome-wide association studies (GWAS) in multi-ethnic populations (1-4). Although familial short stature (FSS) is the most common type of short stature, its genetic profile and impact on bone metabolism remains to be investigated. This GWAS...
