Effects of low oxygen culture on pluripotent stem cell differentiation and teratoma formation
Pluripotent stem cells (PSC) hold promise for the study of embryonic development and the treatment of many diseases. Most pluripotent cell research is performed in incubators with a gas-phase oxygen partial pressure (p02) of 142 mmHg. However, embryonic cells in early development are exposed to a …

An investigation of the molecular biology and genetics of Witches' Broom disease of Protea cynaroides
… culture, while more success was obtained with teratoma tissue. Attempts were made to transmit the disease but these were unsuccessful. Four strains of Agrobacterium tumefaciens were unable to induce tumours on P. cynaroides seedlings. Sections of vascular tissue from teratoma and healthy tissue …

Investigation of genetic PIK3CA activation in genome-edited human pluripotent stem cells
… self-sustained “stemness” in embryoid body and teratoma assays. In comparison, heterozygous mutants behaved similar to wild-type controls under all differentiation paradigms. Furthermore, evidence was obtained that strong activation of PI3K signalling is fully compatible with definitive endoderm …

Encapsulation as a 3D model for human embryonic stem cell propagation and differentiation
… potential for immune-isolation and prevention of teratoma formation by hESCs during transplantation. For the first time conditions were optimized for encapsulation of single cell population of the hESCs in alginate microcapsules with an extended proliferation. A 5-stage ontogeny-based protocol for …

Der Einfluss mechanischer Last auf das Potential multipotenter adulter Keimbahnstammzellen zur kardialen Regeneration
Im Rahmen der vorliegenden Arbeit wurden multipotente adulte Keimbahnstammzellen (maGSCs) der Maus in vivo und in vitro im Hinblick auf ihr Differenzierungspotential unter bestimmten Bedingungen untersucht. In vivo wurde gezeigt, dass sich undifferenzierte maGSCs in normalen Mausherzen ansiedeln …
