Unravelling differential Hes1 dynamics during axis elongation of mouse embryos through single-cell tracking.

The intricate dynamics of Hes expression across diverse cell types in the developing vertebrate embryonic tail have remained elusive. To address this, we have developed an endogenously tagged Hes1-Achilles mouse line, enabling precise quantification of dynamics at the single-cell resolution across various tissues. Our findings reveal striking disparities in Hes1 dynamics between presomitic mesoderm (PSM) and preneural tube (pre-NT) cells.

Development in a Dish- Models of Mammalian Embryonic Development.

Despite decades of research, the complex processes of embryonic development are not fully understood. The study of mammalian development poses particular challenges such as low numbers of embryos, difficulties in culturing embryos , and the time to generate mutant lines. With new approaches we can now address questions that had to remain unanswered in the past.

Glioblastoma stem cells induce quiescence in surrounding neural stem cells via Notch signaling.

There is increasing evidence demonstrating that adult neural stem cells (NSCs) are a cell of origin of glioblastoma. Here we analyzed the interaction between transformed and wild-type NSCs isolated from the adult mouse subventricular zone niche. We found that transformed NSCs are refractory to quiescence-inducing signals.
