Project description:Gene expression profiling was performed of Pax5 wild type bone marrow subsets from common lymphoid progenitors through to Hardy stage F cells. These cells were obtained by flow sorting of bone marrow. Gene expression profiling was performed on 41 samples of RNA extracted from flow sorted B cell precursor populations from common lymphoid progenitor (CLP) through to Hardy stage F. Note that several of the genes expressed in normal mouse B cell progenitors are also involved by deletion/mutation in hypodiploid ALL.

Project description:In order to understand the developmental trajectories of early lymphocyte development it is crucial to prospectively isolate stage and lineage specific cells. It has become clear that early lymphoid progenitor compartments in the bone marrow are molecularly and functionally heterogeneous which warrants further investigation to refine the marker combinations used to isolate these progenitors. An initial antibody screen revealed extensive surface marker heterogeneity amongst early lymphoid progenitors. This heterogeneity was resolved using single cell gene expression assays and single cell in vitro differentiation assays, identifying marker combinations that isolate functionally distinct populations. In addition, using reporter transgenic mice we were able to identify a set of surface markers that can be used alone or in combination with classical targets to identify specific stages of B-cell development. B-cell stages based on transgene expression which were used for screening purposes were verified by RNASeq. The data provides a greater resolution of the complexity of the lymphoid progenitor compartment within the bone marrow than has been understood to date and provides novel tools for the further identification of cell populations in B-lineage development. qPCR gene expression profiling of mouse common lymphoid progenitors (CLPs). Four 96-well plates with pre-amplified single CLP bone marrow cell cDNA (with 10 and 20 cell controls) were loaded on to a 96.96 Dynamic Array Chip for Gene Expression. Samples Ids follow where SS<X> denotes well ID, and P<X>denoted the plate. Controls include well where no RT is performed (noRT) and 10 and 20 cell controls.

Project description:While most blood lineages are assumed to mature through a single cellular and developmental route downstream of hematopoietic stem cells (HSCs), dendritic cells (DCs) can be derived from both myeloid and lymphoid progenitors in vivo. To determine how distinct progenitors can generate similar downstream lineages, we examined the transcriptional changes that accompany loss of in vivo myeloid potential as common myeloid progenitors (CMPs) differentiate into common dendritic cell progenitors (CDPs), and as lymphoid-primed multipotent progenitors (LMPPs) differentiate into all lymphoid progenitors (ALPs). Microarray studies revealed that Interferon regulatory factor 8 (IRF-8) expression increased during each of these transitions. Competitive reconstitutions using Irf8-/- bone marrow demonstrated cell-intrinsic defects in the formation of CDPs and all splenic dendritic cell subsets. Irf8-/- CMPs and, unexpectedly, Irf8-/- ALPs produced more neutrophils in vivo than their wild type counterparts at the expense of DCs. Retroviral expression of IRF-8 in multiple progenitors led to reduced neutrophil production and increased numbers of DCs, even in the granulocyte-macrophage progenitor (GMP), which does not normally possess conventional DC potential. These data suggest that IRF-8 represses a neutrophil module of development and promotes convergent DC development from multiple lymphoid and myeloid progenitors autonomously of cellular context. CMP (Lineage-c-kithiSca-1-CD11c- CD34+ Flk2+CD16/32-CD115- ) or CDP (Lin-c-kitintSca-1-CD34+Flk2+CD16/32-CD115+) were double sorted from the bone marrow of wild type C57BL/6 mice. RNA was extracted from 10,000-30,000 sorted cells using Trizol (Invitrogen) and linear acrylamide (Ambion), amplified using Affymetrix Two-Cycle Amplification and IVT kits (Affymetrix), and hybridized to Affymetrix Mouse Genome 430 2.0 chips.

Project description:In order to understand the developmental trajectories of early lymphocyte differentiation it is crucial to identify linage-restricted progenitors. It has become clear that the classical early lymphoid progenitor compartments in the bone marrow are molecularly and functionally heterogeneous which warrants further investigation to refine the marker combinations used to isolate these progenitors. Herein, an initial antibody screen revealed extensive surface marker heterogeneity amongst early lymphoid progenitors. This heterogeneity was resolved using single cell gene expression assays and single cell in vitro differentiation assays, identifying marker combinations that isolate functionally distinct populations.
