Viability Assay and Osteogenic Induction of Bone Progenitor Cells

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 Vitro Pancreas Organogenesis from Dispersed Mouse Embryonic Progenitors

Filippo De Franceschi, Anne Grapin-Botton, Chiara Greggio

The pancreas is an essential organ that regulates glucose homeostasis and secretes digestive enzymes. Research on pancreas embryogenesis has led to the development of protocols to produce pancreatic cells from stem cells. The whole embryonic organ can be c ...

Amino-polyvinyl Alcohol Coated Superparamagnetic Iron Oxide Nanoparticles are Suitable for Monitoring of Human Mesenchymal Stromal Cells In Vivo

Heinrich Hofmann, Lionel André Maurizi

Mesenchymal stromal cells (MSCs) are promising candidates in regenerative cell-therapies. However, optimizing their number and route of delivery remains a critical issue, which can be addressed by monitoring the MSCs' bio-distribution in vivo using super-p ...

DL4-mediated Notch signaling is required for the development of fetal alpha beta and gamma delta T cells

Freddy Radtke, Ute Koch, Stéphanie Claudinot

T-cell development depends upon interactions between thymocytes and thymic epithelial cells (TECs). The engagement of delta-like 4 (DL4) on TECs by Notch1 expressed by blood-borne BM-derived precursors is essential for T-cell commitment in the adult thymus ...

Reciprocal interactions between endothelial cells and macrophages in angiogenic vascular niches

Michele De Palma, Mario Leonardo Squadrito

The ability of macrophages to promote vascular growth has been associated with the secretion and local delivery of classic proangiogenic factors (e.g., VEGF-A and proteases). More recently, a series of studies have also revealed that physical contact of ma ...

Regulation of innate and adaptive immunity by Notch

Freddy Radtke

Coordinated function of the innate and adaptive arms of the immune system in vertebrates is essential to promote protective immunity and to avoid immunopathology. The Notch signalling pathway, which was originally identified as a pleiotropic mediator of ce ...

Transcription factor ROR alpha is critical for nuocyte development

Freddy Radtke, Ute Koch

Nuocytes are essential in innate type 2 immunity and contribute to the exacerbation of asthma responses. Here we found that nuocytes arose in the bone marrow and differentiated from common lymphoid progenitors, which indicates they are distinct, previously ...

Planar Cell Polarity Controls Pancreatic Endocrine Differentiation

Cédric Cortijo

PCP proteins are restricted to progenitor cells in the embryonic pancreas. The PCP core components Celsr2/3 control endocrine cell differentiation. This effect is mediated by the JNK pathway ...

Molecular and Functional Characterization of Clonogenic Human Thymic Epithelial Cells

Melissa Maggioni

The thymus is a primary lymphoid organ where bone marrow derived T-cell progenitors come in contact with a unique microenvironment able to sustain their maturation into functional T-cells. This fundamental immunological function of the thymus is supported ...

Dual Lineage-Specific Expression of Sox17 During Mouse Embryogenesis

Marine Marie Kraus, Anne Grapin-Botton, Laurence Anne E Lemaire

Sox17 is essential for both endoderm development and fetal hematopoietic stem cell (HSC) maintenance. While endoderm-derived organs are well known to originate from Sox17-expressing cells, it is less certain whether fetal HSCs also originate from Sox17-exp ...
