Description
The E2A transcription factors promote the development of thymus-seeding cells but it remains unknown whether these proteins play a role in T lymphocyte lineage specification or commitment. By examining E2A-dependent genes in developing T cells, we will address whether these proteins are involved in these processes.
Publication Title
E2A transcription factors limit expression of Gata3 to facilitate T lymphocyte lineage commitment.

Description
we have investigated molecular and functional properties in early B-lineage cells from Pax-5 deficient animals crossed to a B-lineage restricted reporter mouse. Gene expression analysis of ex vivo isolated progenitor cells revealed that Pax-5 deficiency has a minor impact on Bcell specification.By comparison of gene expression patterns in ex vivo isolated Pax-5 and Ebf-1 deficient progenitors, it was possible to identify a set of B-cell restricted genes dependent of Ebf-1 but not Pax-5, supporting the idea that B-cell specification and commitment is controlled by distinct regulatory networks.
Publication Title
Single-cell analysis of early B-lymphocyte development suggests independent regulation of lineage specification and commitment in vivo.

Description
Thymic iNKT cell development is divided into four stages (stage 0-3) that are characterised, in C57BL/6 mouse strain, by the differential expression of surface markers, such as CD24, CD44 and NK1.1. During transition from immature to mature iNKT cell subsets, gene expression is tightly regulated. Here, we used microarray analysis to detail the influence of the transcriptional regulator ID3 during iNKT cell maturation in the thymus.
Publication Title

Description
The E-protein transcription factors E2A and HEB play important roles at several stages of hematopoiesis. However, the exact mechanism for theire action and the main targets in the LY6D negative common lymphoid progentior (CLP) compartment remains unknown. By adressing this question, we will gain important infromation regarding the early events leading to B-cell specification.
Publication Title
The transcription factors E2A and HEB act in concert to induce the expression of FOXO1 in the common lymphoid progenitor.

Description
In order to investigate molecular events involved in the regulation of lymphoid lineage commitment, we crossed lamda5 reporter transgenic mice to mice where the GFP gene is inserted into the Rag1 locus. This allowed us to sub-fractionate common lymphoid progenitors (CLPs) and pre-pro-B cells into lamda5-Rag1low, lamda5-Rag1high and lamda5+Rag1high cells. Clonal in vitro differentiation analysis demonstrated that Rag1low cells gave rise to B/T and NK cells. Rag1high cells displayed reduced NK-cell potential with preserved capacity to generate B- and T-lineage cells while the lamda5+ cells were B-lineage restricted. Ebf1 and Pax5 expression was largely confined to the Rag1high populations. These cells also expressed a higher level of the surface protein LY6D providing an additional tool for the analysis of early lymphoid development. These data suggest that the classical CLP compartment composes a mixture of cells with more or less restricted lineage potentials opening new possibilities to investigate early hematopoiesis.

Description
Somatic stem cells mediate tissue maintenance for the lifetime of an organism. Despite the well-established longevity that is a prerequisite for such function, accumulating data argue for compromised stem cell function with age. Identifying the mechanisms underlying age-dependent stem cell dysfunction is therefore key to understand the aging process.
Publication Title
Accumulating mitochondrial DNA mutations drive premature hematopoietic aging phenotypes distinct from physiological stem cell aging.

Description
Loss of one allele of Ebf1 impairs pre-B cell (B220+CD19+CD43low/negIgM-) expansion. In order to better understand the underlying cause of the reduced pre-B cell compartment in Ebf1+/- mice, we sorted pro-B (B220+CD19+CD43highIgM- ) as well as pre-B cells from Wt and Ebf1 heterozygote mutant mice and performed Affymetrix based microarray gene expression analysis.
Publication Title
Early B-cell factor 1 regulates the expansion of B-cell progenitors in a dose-dependent manner.
