In vitro endoderm emergence and self-organisation in the absence of extraembryonic tissues and embryonic architecture

In humans, mice, and other mammals key internal organs such as the gut, the lungs, the pancreas, and the liver all derive from the same embryonic tissue: the endoderm. The development of all of these structures thus depends on a same set of early cells, an ...

Boundaries in animal genomes delimit contact domains with enhanced internal contact frequencies and have debated functions in limiting regulatory cross-talk between domains and guiding enhancers to target promoters. Most mammalian boundaries form by stalli ...

To regenerate or not to regenerate: Vertebrate model organisms of regeneration-competency and -incompetency

Can Aztekin

Why only certain species can regenerate their appendages (e.g. tails and limbs) remains one of the biggest mysteries of nature. Unlike anuran tadpoles and salamanders, humans and other mammals cannot regenerate their limbs, but can only regrow lost digit t ...

Generation of a Gal4-dependent gene recombination and illuminating mouse

Freddy Radtke

Cell labeling technologies, including the Cre/loxP system, are powerful tools in developmental biology. Although the conventional Cre/loxP system has been extensively used to label the expression of specific genes, it is less frequently used for labeling p ...

Classic microsurgical techniques, such as those used in the early 1900s by Mangold and Spemann, have been instrumental in advancing our understanding of embryonic development. However, these techniques are highly specialized, leading to issues of inter-ope ...

The CT-cube: A framework for the design and the assessment of computational thinking activities

Francesco Mondada, Alberto Piatti, Laila Abdelsalam El-Hamamsy

Computational thinking is a fundamental competence that is being introduced in K-12 and succeeding curricula worldwide. Despite this huge effort, many computational thinking models in the literature do not explicitly take into consideration the pupils’ age ...

Tissue morphogenesis, homoeostasis and repair require cells to constantly monitor their three-dimensional microenvironment and adapt their behaviours in response to local biochemical and mechanical cues. Yet the mechanical parameters of the cellular microe ...

Shaping embryonic tissues into their functional morphologies requires cells to control the physical state of the tissue in space and time. While regional variations in cellular forces or cell proliferation have been typically assumed to be the main physica ...

Appendage regeneration is context dependent at the cellular level

Can Aztekin

Species that can regrow their lost appendages have been studied with the ultimate aim of developing methods to enable human limb regeneration. These examinations highlight that appendage regeneration progresses through shared tissue stages and gene activit ...

Cancer Cells Retrace a Stepwise Differentiation Program during Malignant Progression

Douglas Hanahan, Krisztian Homicsko, Mohammad Sadegh Saghafinia, Stephan Wullschleger, Iacovos Michael, Giovanni Ciriello

Pancreatic neuroendocrine tumors (PanNET) comprise two molecular subtypes, relatively benign islet tumors (IT) and invasive, metastasis-like primary (MLP) tumors. Until now, the origin of aggressive MLP tumors has been obscure. Herein, using multi-omics ap ...
