Organ sculpting requires directed physical force generation. Force imbalances are primarily thought to arise from within cells. A new study, however, demonstrates that an extracellular-matrix-based stiffness gradient in the Drosophila egg chamber instructs tissue elongation.
器官塑形需要定向的物理力生成。力的失衡主要被认为是由细胞内部引起的。然而，一项新的研究表明，果蝇卵室中基于细胞外基质的硬度梯度指导组织伸长。
