Synchronized Temporal-spatial Analysis via Microscopy and Phoshoproteomics (STAMP) of Quiescence.

Tightly coordinated cell cycle regulation is essential for homeostasis. G , or quiescence, is especially crucial for cells to respond to extracellular stimuli. Little is known about the mechanisms that establish the G program, though the primary cilium (a key signaling hub formed only in G ) is the most widely recognized marker.
