Genomics of Preaxostyla Flagellates Illuminates the Path Towards the Loss of Mitochondria

Shweta Vinodrai Pipaliya, Marek Elias

The notion that mitochondria cannot be lost was shattered with the report of an oxymonad Monocercomonoides exilis, the first eukaryote arguably without any mitochondrion. Yet, questions remain about whether this extends beyond the single species and how th ...

Bioinspired gradient scaffolds for osteochondral tissue engineering

Yang Liu

Repairing articular osteochondral defects present considerable challenges in self-repair due to the complex tissue structure and low proliferation of chondrocytes. Conventional clinical therapies have not shown significant efficacy, including microfracture ...

Extensive programmed centriole elimination unveiled in C. elegans embryos

Pierre Gönczy, Nils Kalbfuss

Centrioles are critical for fundamental cellular processes, including signaling, motility, and division. The extent to which centrioles are present after cell cycle exit in a developing organism is not known. The stereotypical lineage of Caenorhabditis ele ...

Primary data for EPFL thesis "Characterisation of conditional alleles of the Schizosaccharomyces pombe cytokinesis regulator byr4"

Michael Grüner Vindfeldt

Regulation of cytokinesis is essential for the cell during its division cycle. Failure to do so can lead to aneuploidy, which can be fatal and lead to senescence or cancer. A useful model organism for studying cytokinesis in eukaryotes is Schizosaccharomyc ...
