The application of stem cells in drug screening and regenerative therapy has led to important advances in basic biology and biomedicine. Such strategies require high cell numbers and the efficient maturation into faithful functional organ or tissue units. ...
Functional analysis of primary tissue-specific stem cells is hampered by their rarity. Here we describe a greatly miniaturized microfluidic device for the multiplexed, quantitative analysis of the chemotactic properties of primary, bone marrow-derived mese ...
Stem cells play a key role in a wide range of biological processes, in large part due to their ability to self-renew or differentiate into specialized cell types in response to various biological cues. In vivo, stem cells reside in a complex microenvironme ...
First, it will be investigated if amino-polyvinyl alcohol-coated superparamagnetic iron oxide nanoparticles (A-PVA-SPIONs) are suitable for MRI contrast enhancement in bone marrow. Second, the impact of A-PVA-SPION exposure in vivo on the viability and key ...
The present invention relates to a specific marker for stem cells having long-term multi-lineage blood reconstitution capability and uses thereof for the preparation of cell composition in view of hematopoietic stem cell medicine and in particular regenera ...
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 ...
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 ...
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 ...
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 perivascular niche is a complex microenvironment containing mesenchymal stem cells (MSCs), among other perivascular cells, as well as temporally organized biochemical and biophysical gradients. Due to a lack of conclusive phenotypic markers, MSCs' iden ...
