Understanding how cell-scale mechanics give rise to tissue-scale phenomena remains challenging due to the inherent complexity of biological systems. This seminar presents a reductionist strategy using micropatterning to create minimal tissue models that isolate specific cellular processes for quantitative study. The first part addresses the mechanics of T1 transitions in tissues\, the neighbor exchange events driving tissue remodeling during morphogenesis. Using cell quadruplets on cross-shaped micropatterns\, we experimentally measured the effective energy landscape of T1 transitions and validated vertex model predictions\, revealing how geometric constraints set energy barriers that active forces must overcome. The second part turns to mechanical heterogeneity in tissues. While cell-to-cell variability is ubiquitous\, whether it functions as a driver of collective behavior or merely represents noise remains unclear. Using controlled mixtures of wild-type and vimentin-knockout glioblastoma cells\, we systematically investigate how the degree and spatial organization of mechanical heterogeneity shapes tissue mechanics.

We are particularly interested in the specification between epiblast cells (Epi) and primitive endoderm cells (PrE) which takes place during the first 3 days in mice\, corresponding to the first 6 days in humans. The Epi cells produce all the cells of the future individual and its descendants and are the source of the famous pluripotent ES cells. Epi and PrE cells are specified from Inner Cell Mass (ICM) cells\, and they express the transcription factors NANOG and GATA6\, respectively\, according to a salt and pepper pattern. How is this pattern is acquired has been the focus of our research\, which highlights a combination of stochastic and deterministic mechanisms.

Combining in toto cell lineage reconstruction and a custom whole-mount spatial transcriptomics —in the same animal- my work shows RB neurons possess extremely simple cell lineages and link them to dozens of transcription factors and somatosensory genes in space. Spatiotemporal analysis of RB subtype emergence reveals that it follows a staggered-layer logic\, with a ‘pan-RB program’ preceding a stochastic ‘hybrid neurotrophin receptor’ state that resolves into mutually-exclusive subclasses\, followed by specialized functional subtypes.  I also define the regulatory mechanism by transcription factors underlying the seemingly stochastic\, yet robust emergence of the observed neuronal subtypes across time. I also discuss this mechanism is likely conserved across Anamniotes. This work demonstrates that zebrafish RB neurons are an excellent model to study the precise molecular mechanisms underlying the development of neuron diversity at the single-cell level.
