The pleiotropic cytokine interleukin-1β (IL-1β) can promote physiological cell migration, as well as cancer cell invasion and metastasis. Its role in human trophoblast invasion, however, has not been satisfactorily answered since direct, indirect as well as no effects on trophoblast motility have been published. Therefore, the role of IL-1β has been re-evaluated by exclusively using human primary...
Invasive, extravillous trophoblasts (EVT) of the human placenta are critically involved in successful pregnancy outcome since they remodel the uterine spiral arteries to increase blood flow and oxygen delivery to the placenta and the developing fetus. To gain more insights into their biological role different primary cell culture models are commonly utilised. However, access to early placental tissue...
The paper focuses on similarity-based texture classification and analysis techniques. A novel similarity measure is introduced in this context that takes also structural spatial information of the intensity distribution of the textured image into account which turns out to be advantageous compared to standard concepts as for example pixel-by-pixel based similarity measures like cross-correlation or...
Recent evidence from the literature suggested that hCG preparations purified from urine of pregnant women, which are widely used in in vitro studies and IVF programs, may contain contaminants such as EGF. To determine the putative biological effects of the contaminating growth factor, we here investigated distinct trophoblast differentiation processes in the presence of various hCG compounds. Western...
