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: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. In addition, surface markers that could be used alone or in combination with classical targets to capture specific stages of B-cell development were identified in the screen. 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.

Project description:Natural Killer (NK) cells at different developmental stages (common lymphoid progenitor (CLP), innate lymphoid cell progenitors (ILCP), and refined NK progenitor (NKP)) were collected from Vav1+iCre FOXO1,3flox/flox mice (C57BL/6 background). Total RNA was harvested and sequenced with a strand-specific paired-end RNA-seq protocol.

Project description:The transcription factor PU.1 is a central regulator of hematopoiesis, required for the normal differentiation of the myeloid and lymphoid lineages. Due to its essential role in early development and the importance of PU.1 in regulating several defining markers of lymphoid progenitors, its precise function in early lymphopoiesis has remained unclear. Using conditional mutagenesis and alternative lineage identification strategies, we demonstrate the developmental stage restricted function for PU.1 in early lymphopoiesis. PU.1 was required for efficient generation of “lymphoid primed multipotent progenitors (LMPPs)” from hematopoietic stem cells and was essential for the subsequent formation of “common lymphoid progenitors (CLPs)”. In contrast, further differentiation into the B cell lineage was independent of PU.1. The function of PU.1 was dosage sensitive as loss of one allele decreased all stages of early lymphopoiesis. PU.1 expression mirrored its functional role during lineage differentiation. PU.1 peaked at LMPPs and was maintained in CLPs, before being down regulated in committed pro-B cells. Examination of the transcriptional changes in PU.1 conditionally deficient LSK cells revealed that PU.1 activates lymphoid and dendritic cell associated genes in LMPPs, while repressing genes normally expressed in neutrophils. These data identify PU.1 as a critical regulator of lymphoid priming and the transition between LMPPs and CLPs.
