DRAG in situ barcoding reveals an increased number of HSPCs contributing to myelopoiesis with age.

Project description:Ageing is associated with changes in the cellular composition of the immune system. During ageing, hematopoietic stem and progenitor cells (HSPCs) that produce immune cells are thought to decline in their regenerative capacity. However, HSPC function has been mostly assessed using transplantation assays, and it remains unclear how HSPCs age in the native bone marrow niche. To address this issue, we present an in situ single cell lineage tracing technology to quantify the clonal composition and cell production of single cells in their native niche. Our results demonstrate that a pool of HSPCs with unequal output maintains myelopoiesis through overlapping waves of cell production throughout adult life. During ageing, the increased frequency of myeloid cells is explained by greater numbers of HSPCs contributing to myelopoiesis rather than the increased myeloid output of individual HSPCs. Strikingly, the myeloid output of HSPCs remains constant over time despite accumulating significant transcriptomic changes throughout adulthood. Together, these results show that, unlike emergency myelopoiesis post-transplantation, aged HSPCs in their native microenvironment do not functionally decline in their regenerative capacity.

Ribosome profiling of NIH-3T3 cells infected with MCMV

Project description:NIH-3T3 cells were infected with wildtype MCMV at a multiplicity of infection (MOI) of 10. Ribosome profiling was performed at the indicated times of infection as described in Rutkowski et al., Nature Communications 2015.

Transcriptome of rNLS8 mice and controls injected with non-targeting control ASO

Project description:We asked how knockdown of genes associated with neurodegeneration using antisense oligonucleotides (ASO) affects disease phenotypes in an inducible TDP-43 transgenic mouse model (rNLS8, Walker et al., Acta Neuropathologica 2015) backcrossed to the C57BL/6 background. This dataset includes only the non-targeting control, which was also used as a replication cohort for transcriptional changes in rNLS8 mice (Rezaei et al., in revision at Nature Communications). We show cholesterol dysmetabolism and marker genes of disease-associated oligodendrocytes in the brain of rNLS8 mice. Data from mice receiving the targeting ASOs will be made available upon publication of the manuscript (Kocsis-Jutka et al, in preparation).

Gene expression in zebrafish following knockdown of pitx2 or tbx5

Project description:Key regulators of septum formation between the left and right ventricle in mammals, including the transcription factors TXB5 and PITX2, feature loss-of-function phenotypes that affect development of the two-chambered zebrafish heart, suggesting uncharacterized primordial functions of these septation regulators prior to the evolution of any physical boundaries between heart chambers. Data is as published in Mosimann & Panakova et al (Nature Communications, 2015)

Expression analysis of draculin (drl) expressing cells in embryonic zebrafish

Project description:drl expression initiates during gastrulation and condenses as a band of cells at the prospective lateral embryo margin. In late epiboly, drl:EGFP is detectable as a band of scattered EGFP-fluorescent cells; after gastrulation, drl:EGFP-positive cells coalesce at the embryo margin that then in somitogenesis break down into the anterior and posterior lateral plate with subsequent cell migrations that form the posterior vascular/hematopoietic stripes and the anterior cardiovascular and myeloid precursors. Data is as published in Mosimann & Panakova et al (Nature Communications, 2015)
