BACKGROUND Human multipotent mesenchymal stromal cells (MSCs) are promising candidates for a growing spectrum of regenerative and immunomodulatory cellular therapies. Translation of auspicious experimental results into clinical applications has been limited by the dependence of MSC propagation from fetal bovine serum (FBS). STUDY DESIGN AND METHODS The(More)
Mesenchymal stromal cells (MSCs) are promising candidates for novel cell therapeutic applications. For clinical scale manufacturing, human factors from serum or platelets have been suggested as alternatives to fetal bovine serum (FBS). We have previously shown that pooled human serum (HS) and thrombin-activated platelet releasate in plasma (tPRP) support(More)
The generation of endothelial progenitor cells (EPCs) from blood monocytes has been propagated as a novel approach in the diagnosis and treatment of cardiovascular diseases. Low-density lipoprotein (LDL) uptake and lectin binding together with endothelial marker expression are commonly used to define these EPCs. Considerable controversy exists regarding(More)
Extracellular vesicles (EVs), such as exosomes and microvesicles, are released by different cell types and participate in physiological and pathophysiological processes. EVs mediate intercellular communication as cell-derived extracellular signalling organelles that transmit specific information from their cell of origin to their target cells. As a result(More)
In the last decade there has been a rapid expansion in clinical trials using mesenchymal stromal cells (MSCs) from a variety of tissues. However, despite similarities in morphology, immunophenotype, and differentiation behavior in vitro, MSCs sourced from distinct tissues do not necessarily have equivalent biological properties. We performed a genome-wide(More)
Vessel wall-derived somatic endothelial colony-forming progenitor cells (ECFCs) are key players in vascular homeostasis and regeneration. Due to their robust proliferative potential and profound vessel-forming capacity, ECFCs are considered to represent an attractive tool for vascular regenerative medicine and a promising target for antiangiogenic tumor(More)
Mesenchymal stromal cells (MSC) are currently tested in a large number of clinical trials and raise high hope in regenerative medicine. These cells have to be expanded in vitro before transplantation and several studies demonstrated that long-term culture evokes continuous changes in MSC: proliferation rate decays, the cell size increases, differentiation(More)
BACKGROUND Ex vivo expansion of multipotent mesenchymal stromal cells (MSCs) is a prerequisite for evaluating their therapeutic potential in ongoing clinical trials. Even large volumes of starting material and extended culture periods, however, do not necessarily produce 2 x 10(6) MSCs per kg per adult patient. A new two-step procedure has been devised to(More)
Stem cell-based therapies are a promising prospect for regenerative medicine. Particularly, human multipotent mesenchymal stromal cells (MSCs) are currently in focus regarding their regenerative and immune modulating capacities. An increasing number of clinical trials investigating MSC efficiency and safety are ongoing. Ex vivo propagation of human MSCs is(More)
Adult mesenchymal stem cells (MSCs) are considered as valuable mediators for tissue regeneration and cellular therapy. This study was performed to develop conditions for regularly propagating a clinical quantity of > 2 x 10(8) MSCs without animal serum from small bone marrow (BM) aspiration volumes within short time. We established optimized culture(More)
