Divisional history and pluripotency of human hematopoietic stem cellsM Punzel
Medizinische Poliklinik, University of Heidelberg, Hospital Str 3, 69115 Heidelberg, Germany
Ann N Y Acad Sci 938:72-81; discussion 81-2. 2001..In addition, the much more primitive Myeloid-Lymphoid Initiating Cells (ML-IC) are predominantly found in the PKH-bright population. Thus, primitive function of individual candidate HSCs closely related to their divisional behavior...
The microenvironment of AFT024 cells maintains primitive human hematopoiesis by counteracting contact mediated inhibition of proliferationMichael Punzel
Department of Medicine, Division of Hematology and Stem Cell Institute, University of Minnesota, Minneapolis, MN, USA
Cell Commun Adhes 9:149-59. 2002..In conclusion, AFT024 cells produce factor(s), that counteract contact induced growth inhibition of primitive human hematopoietic progenitors, leading to expansion of these cells in contact with the microenvironment...
Single adult human CD34(+)/Lin-/CD38(-) progenitors give rise to natural killer cells, B-lineage cells, dendritic cells, and myeloid cellsJ S Miller
Department of Medicine, University of Minnesota Cancer Center, Minneapolis, MN 55455, USA
Blood 93:96-106. 1999..This study provides new insights into the role of the microenvironment niche, which governs the earliest events in lymphoid development...
Functional analysis of initial cell divisions defines the subsequent fate of individual human CD34(+)CD38(-) cellsMichael Punzel
Department of Medicine V, University of Heidelberg, Heidelberg, Germany
Exp Hematol 30:464-72. 2002..Primitive ML-IC can be distinguished from committed CFC by initial quiescence or asymmetric divisions. Committed CFC cycle rapidly and symmetrically...
The symmetry of initial divisions of human hematopoietic progenitors is altered only by the cellular microenvironmentMichael Punzel
Department of Medicine V, University of Heidelberg, Heidelberg, Germany
Exp Hematol 31:339-47. 2003..Exposure to AFT024 cells also increased proliferation and asymmetric divisions of committed CFC. Hence direct communication between hematopoietic progenitors with stroma cells is required for maintaining self-renewal potential...
Hematopoietic stem cells: can old cells learn new tricks?Anthony D Ho
Department of Medicine V, University of Heidelberg, Germany
J Leukoc Biol 73:547-55. 2003....
Lineage development of hematopoietic stem and progenitor cellsBernd Giebel
Institute for Transplantation Diagnostics and Cellular Therapeutics, Heinrich Heine University, Dusseldorf, Germany
Biol Chem 389:813-24. 2008..Together with some phenotypic criteria that characterize different subsets of multipotent and lineage-restricted progenitor cells, we summarize these recent findings here...
Nucleofection, an efficient nonviral method to transfer genes into human hematopoietic stem and progenitor cellsGregor von Levetzow
Institute for Transplantation Diagnostics and Cell Therapeutics, , , Germany
Stem Cells Dev 15:278-85. 2006..Therefore, we conclude, the nucleofection method is a reliable and efficient method to manipulate primitive hematopoietic cells genetically...
The neurotransmitter GABA is a potent inhibitor of the stromal cell-derived factor-1alpha induced migration of adult CD133+ hematopoietic stem and progenitor cellsJeanette Seidel
Institute of Immunology, Witten Herdecke University, 58448 Witten, Germany
Stem Cells Dev 16:827-36. 2007..In summary, the neurotransmitter GABA is a potent blocker of the SDF-1alpha-induced migration of CD133(+) HSPCs from mobilized peripheral blood...
Relevance of C1 and C2 epitopes for hemopoietic stem cell transplantation: role for sequential acquisition of HLA-C-specific inhibitory killer Ig-like receptorJohannes C Fischer
Institute for Transplantation Diagnostics and Cell Therapeutics, Heinrich Heine University Dusseldorf, Moorenstrasse 5, D 40225 Dusseldorf, Germany
J Immunol 178:3918-23. 2007..These findings define a novel determinant for understanding the role of NK cells in clinical hemopoietic stem cell transplantation...
Primitive human hematopoietic cells give rise to differentially specified daughter cells upon their initial cell divisionBernd Giebel
Institute for Transplantation Diagnostics and Cell Therapeutics, , , Germany
Blood 107:2146-52. 2006..In addition, we describe a novel human hematopoietic progenitor cell that has the capacity to form natural killer (NK) cells as well as macrophages, but not cells of other myeloid lineages...
Cytokine combinations differentially influence the SDF-1alpha-dependent migratory activity of cultivated murine hematopoietic stem and progenitor cellsSusannah H Kassmer
Institute of Immunology, Witten Herdecke University, Stockumer Strasse 10, Witten, Germany
Biol Chem 389:863-72. 2008..This indicates that hematopoietic cytokines can have a significant impact on SDF-1alpha-stimulated migratory activity and the underlying intracellular signaling processes in cultivated HSPCs...
