Mechanical forces can affect the way tissue grows. Ideally, we want to characterize them without interfering with the processes we are studying. Is there a way to achieve this?

Speaking of time, @osvaldo-chara.bsky.social 's lab recently developed a new method, ForSys, that uses all available dynamic information. It also tracks the elements of the tissue over time and uses their movement to further inform the stress inference algorithm.

canaztekin.bsky.social canaztekin.bsky.social @canaztekin.bsky.social · Oct 21
🔬 Limb regeneration depends on regenerative signaling center cells — but how do these cells influence others to proliferate, migrate, or differentiate?
We’re recruiting PhD or Postdoc candidates to explore this with our collaborator @osvaldo-chara.bsky.social !
