We describe here the construction of a new version of the Escherichia coli-Streptomyces shuttle cloning vector pIJ6902, which carries the original thiostrepton-inducible PtipA as well as the integrative and cloning systems, but with the E. coil low copy nu ...
Image-based identification of cultured stem cells and noninvasive evaluation of their proliferative capacity advance cell therapy and stem cell research. Here we demonstrate that human keratinocyte stem cells can be identified in situ by analyzing cell mot ...
The goal of this thesis was to evaluate the use of artificial transposon systems for the generation of recombinant cell pools and cell lines with Chinese hamster ovary (CHO) cells as the production host. Transposons are naturally occurring genetic elements ...
Although urothelial progenitor-like cells have been described in the human urinary tract, the existence of stem cells remains to be proven. Using a culture system that favors clonogenic epithelial cell growth, we evaluated and characterized clonal human ur ...
Proteins are a ubiquitous and indispensable element for every living organism, from simple bacteria to mammals. Already in the simplest organisms, there exist some thousands of different protein species that take up a great variety of structures, and thus ...
Transplantation of donor cornea is widely performed with a high success rate to treat patients with impaired corneal transparency. However the limited number of donors has led scientists to search for new technologies and treatments, including stem cell th ...
Chinese hamster ovary (CHO) cells are a source of multi-ton quantities of protein pharmaceuticals. They are, however, immortalized cells, characterized by a high degree of genetic and phenotypic diversity. As is known for any biological system, this divers ...
