Název v původním jazyce

Structured Surfaces Mimicking in vivo Tissue Architecture

Popis výsledku v původním jazyce

Tissue engineering depends on the availability of appropriate cells seeded on appropriate substrates. Human induced pluripotent stem cells (hiPSC) retain the ability to self-renew and differentiate into any somatic cells and their usage does not invoke any ethical controversy compared to human embryonic stem cells. Another advantage of hiPSC is that the patienťs own cells can be used for therapy and treatment. Therefore, they belong to the most appropriate lineages of tissue engineering testing. Another important aspect in tissue engineering is the kind of substrate on which cells grow. However, there is only limited information available on the impact of surface properties and structures on iPSC behavior. Thus, the influence of a hierarchically structured surface at the level of macro/meso/micro topography on the attachment and maturation of hiPSC-derived cardiomyocytes (hiPSC-CM) was investigated within this study. The structured substrates prepared here mimic the in vivo microenvironment They were tested in the context of their impact on the cardiomyogenesis of humaninduced stem cells. Both types of substrate were suitable for culturing induced cells and, in addition, were found not to inhibit the maturation of cardiomyocytes. The results provided a comprehensive view of the main parameters influencing celUmaterial interactions, with respect to substrate architecture and surface energy. The substrates prepared here offer a new possibility for the experimental set-up ofin vitro experiments.
