Developmental Biology: Tension at the Border [PDF]
Current Biology, 2009 A combination of biophysical measurements and computer simulation shows that a localised increase in cell bond tension prevents cell mixing at the anterior-posterior compartment boundary of Drosophila wing imaginal discs.

iScience, 2021 Summary: The mitochondrial unfolded protein response (UPRmt) is an organellar stress signaling pathway that functions to detect and restore disruption of mitochondrial proteostasis.

iScience, 2021 Summary: Epithelia form protective permeability barriers that selectively allow the exchange of material while maintaining tissue integrity under extreme mechanical, chemical, and bacterial loads. Here, we report in the Drosophila follicular epithelium a

Cancer Networks: A general theoretical and computational framework for understanding cancer [PDF]
arXiv, 2011 We present a general computational theory of cancer and its developmental dynamics. The theory is based on a theory of the architecture and function of developmental control networks which guide the formation of multicellular organisms. Cancer networks are special cases of developmental control networks.

Horizontal mtDNA transfer between cells is common during mouse development
iScience, 2022 Summary: Cells transmit their genomes vertically to daughter cells during cell divisions. Here, we demonstrate the occurrence and extent of horizontal mitochondrial (mt)DNA acquisition between cells that are not in a parent-offspring relationship ...

Robust and Irreversible Development in Cell Society as a General Consequence of Intra-Inter Dynamics [PDF]
, 1999 A dynamical systems scenario for developmental cell biology is proposed, based on numerical studies of a system with interacting units with internal dynamics and reproduction. Diversification, formation of discrete and recursive types, and rules for differentiation are found as a natural consequence of such a system.

Non-equilibrium statistical physics, transitory epigenetic landscapes, and cell fate decision dynamics [PDF]
arXiv, 2020 Statistical physics provides a useful perspective for the analysis of many complex systems; it allows us to relate microscopic fluctuations to macroscopic observations. Developmental biology, but also cell biology more generally, are examples where apparently robust behaviour emerges from highly complex and stochastic sub-cellular processes.
