Furthermore, AP products have gained increasing importance as potential anti-cancer agents. However, the ingredients of the available products vary greatly with the origin, the type of production and processing, which could have significant consequences for their biological effects. Therefore, the composition and biological influence of five distinct AP powders, which were acquired commercially or produced at a public biotechnology institute, were investigated in regard to their endothelialization capacity using a cell impedance- (CI) based measurement method. The study revealed that the AP composition and especially the influence on HUVEC proliferation differed significantly between the five AP powders up to 109\%. Thus, it could be shown that the method used allows the reliable detection of quantitative differences in biological effects of different AP preparations.}, language = {en} } @misc{KruegerGengeSteinbrechtKuepperetal., author = {Kr{\"u}ger-Genge, Anne and Steinbrecht, Susanne and K{\"u}pper, Jan-Heiner and Lendlein, Andreas and Jung, Friedrich}, title = {Evidence for cytostatic effect of cyclophosphamide on human vein endothelial cells in cancer therapy: preliminary in vitro results.}, series = {Clinical Hemorheology and Microcirculation}, volume = {69}, journal = {Clinical Hemorheology and Microcirculation}, number = {1-2}, issn = {1875-8622}, doi = {10.3233/CH-189125}, pages = {267 -- 276}, language = {en} } @misc{JungJungKruegerGengeetal., author = {Jung, Friedrich and Jung, Conrad H.
