Stem cell therapies hold tremendous potential for tissue and organ regeneration. Yet, there remains significant need for better ex vivo culture and manipulation methods. On the one hand, many tissue-specific stem cells cannot be propagated without causing ...
Hematopoietic stem cells (HSCs) are responsible for life-long production of all mature blood cells. This unique characteristic makes them an ideal candidate for cell-based therapies to treat various hematological malignancies. Their extensive use in the cl ...
The in vitro expansion of hematopoietic stem cells (HSC) for clinical applications is hampered by a rapid loss of HSC blood reconstitution capability in culture. While these rare cells can be stimulated to massively proliferate, cell divisions mostly resul ...
Regulated blood production is achieved through the hierarchical organization of dormant hematopoietic stem cell (HSC) subsets that differ in self-renewal potential and division frequency, with long-term (LT)-HSCs dividing the least. The molecular mechanism ...
A population of monocytes, known as Ly6C(lo) monocytes, patrol blood vessels by crawling along the vascular endothelium. Here we show that endothelial cells control their origin through Notch signalling. Using combinations of conditional genetic deletion s ...
Regulated transgene expression may improve the safety and efficacy of hematopoietic stem cell (HSC) gene therapy. Clinical trials for X-linked chronic granulomatous disease (X-CGD) employing gammaretroviral vectors were limited by insertional oncogenesis o ...
Tissue engineering scaffolds are the new approach to replace common bone grafts. The first aim of this project was to investigate whether bone progenitor cells used in previous studies can undergo osteogenic differentiation. In osteogenic staining experime ...
In a classical view of hematopoiesis, the various blood cell lineages arise via a hierarchical scheme starting with multipotent stem cells that become increasingly restricted in their differentiation potential through oligopotent and then unipotent progeni ...
Integrins play an important role in haematopoietic stem cell (HSC) maintenance in the bone marrow niche. Here, we demonstrate that Periostin (Postn) via interaction with Integrin-alpha v (Itgav) regulates HSC proliferation. Systemic deletion of Postn resul ...
Haematopoietic stem cells (HSCs) differ from their committed progeny by relying primarily on anaerobic glycolysis rather than mitochondrial oxidative phosphorylation for energy production. However, whether this change in the metabolic program is the cause ...
