Degenerative joint diseases caused by rheumatism, joint dysplasia or traumata are
particularly widespread in countries with high life expectation. Although there is no absolutely …

Introduction: In vitro expansion and differentiation of mesenchymal stem cells (MSC) rely on
specific environmental conditions, and investigations have demonstrated that one crucial …

Hematopoietic stem cells (HSCs) maintain the turnover of mature blood cells during steady
state and in response to systemic perturbations such as infections. Their function critically …

Background Hematopoiesis is a complex process involving different cell types and feedback
mechanisms mediated by cytokines. This complexity stimulated various models with …

Background In vitro cultivated stem cell populations are in general heterogeneous with
respect to their expression of differentiation markers. In hematopoietic progenitor populations, …

Ball bearings are commonly used in high speed turbomachinery and have a critical influence
on the rotordynamic behavior. Therefore, a simulation model of the bearing to predict the …

Adult stem cells persist lifelong in the organism, where they are responsible for tissue homeostasis
and repair. It is commonly assumed that their maintenance and function are facilitated …

The molecular mechanisms by which heterogeneity, a major characteristic of stem cells, is
achieved are yet unclear. We here study the expression of the membrane stem cell antigen-1 (…

The hematopoietic stem cell (HSC) niche provides essential microenvironmental cues for
the production and maintenance of HSCs within the bone marrow. During inflammation, …

Background The diagnosis of phaeochromocytoma is commonly performed by the
measurements of plasma‐free normetanephrine and metanephrine. Plasma‐deconjugated …
