Introduction of a Geminin mScarlet Reporter into H2B-mTurq2 hiPSCs for Live-cell Imaging of Proliferation and Cell Cycling
Summary
We previously generated a doxycycline-inducible H2B-mTurq2 reporter in hiPSCs to track cells and study cell division and apoptosis. To improve visualization of cycling cells, we introduced a ubiquitously transcribed mScarletI-Geminin (GMMN) (1-110) into the previously untargeted second AAVS1 allele. Fusion to the N-terminal part of GMNN provided tightly controlled mScarletI expression during the cell cycle. mScarletI fluorescence increased gradually from the S-phase through the M-phase of the cell cycle and was lost at the metaphase-anaphase transition. The resulting hiPSC reporter line generated, which we named ProLiving, is a valuable tool to study cell division and cell cycle characteristics in living hiPSC-derived cells.
