Abstract
Abstract Cell growth during the cell cycle must be coordinated with genome replication and segregation, but the mechanisms underlying this coordination are poorly understood, particularly in mammalian cells. My lab is developing suspended microchannel resonators that can precisely measure the size of single cells – mass, volume and density – over time. Using a microfluidic system for culturing single cells over multiple generations while cell mass and cell cycle progression were continuously measured, we monitored over 1,000 hours of single cell growth from mouse lymphoblasts (L1210). I will present recent data from this system and discuss preliminary experiments where the precision cell sizing capabilities of the resonator are used for biomarker analysis.
