Why the study?
Despite progress in understanding the molecular composition and structure of sarcomeres, the physical mechanisms underlying sarcomere assembly during development remain poorly understood.
This review proposes a new biophysical model for sarcomere self-assembly that integrates the pre-myofibril hypothesis, the stitching model, and tension-driven self-organization.
