Description
Haematopoietic stem cells can differentiate into all blood cell types. In this process, cells become progressively restricted to a single cell type. The order in which differentiating cells loose lineage potential, and the prospective isolation of cells with a defined potential remains a long-standing question. We performed gene expression analysis of haematopoietic cells from Gata1-EGFP reporter mice, leading to a model for hematopoiesis where the initial lineage decision consists of a seperation of erythroid/megakaryocyte/mast cell/eosinophil potential from lymphopoietic/monocyte/neutrophil potential Overall design: Find unbiased heterogeneity in the preGM hematopoietic progenitor population

Description
LMP2A of Epstein-Barr virus is a receptor that mimics an activated B cell receptor, BCR. K1 and K15, related receptors of Kaposi sarcoma-associated herpes virus, KSHV, are expressed in virus-associated tumors but their functions are less obvious. We addressed this uncertainty with mutant EBVs encoding the KSHV genes K1 or K15 in lieu of LMP2A and infected primary human B cells with them. K1 and K15 encoded proteins appear to have noncomplementing redundant functions in this model but our findings suggest that both KSHV proteins can replace LMP2As key activities contributing to the survival, activation and proliferation of B cells.

Description
LEM Domain proteins are key components of the nuclear lamina. Mutations in LEM-D proteins cause dystrophic diseases associated with compromised adult stem cells, yet it remains unclear how LEM-D proteins support stem cell function. Studies described here use the homologue of the LEM-D protein emerin in Drosophila, Otefin (Ote) as a model to understand LEM-D protein function in adult stem cells. Loss of Ote causes female sterility due to a complex germline stem cell (GSC) phenotype that includes both an early block in germline differentiation followed by GSC death. In vivo cell cycle analysis revealed that ote mutant GSCs display a lengthened S phase.We find that loss of the DNA Damage Response (DDR) Chk2 is able to not only rescue the lengthened S phase, but also GSC death and the block in germline differentiation. Activation of detrimental checkpoint in absence of Ote is conserved in both male and female GSCs and surprisingly occurs independent of detectable canonical DDR triggers, including transposon de-repression and DNA damage. Two defects were found to occur upstream of Chk2 activation: nuclear lamina morphological defects and altered heterochromatin organization. Together, our data identify the primary cause for a compromised adult stem cell population in the absence of a LEM-D protein.
