During organismal growth, body parts expand proportionally with one another and with the body as a whole, but the signals mediating this scalar expansion have been elusive. In this issue of Developmental Cell, Ho and Treisman uncover a signal transduction pathway that coordinates muscle growth and neuromuscular junction expansion.

放眼全球，就地采取行动：扩大运动神经元的增长。

在有机体生长期间，身体各部分彼此之间以及与整个身体成比例地扩展，但是介导这种标量扩展的信号却难以捉摸。在本期《发育细胞》中，Ho和Treisman发现了一种信号转导途径，可协调肌肉生长和神经肌肉接头的扩展。
