Live cell isolation by laser microdissection with gravity transfer
Author(s): Oleg V. Podgorny

Paper Abstract

Laser microdissection by pulsing ultraviolet laser allows the isolation and recultivation of live cells based on morphological features or/and fluorescent labelling from adherent cell cultures. Previous investigations described only the use of the laser microdissection and pressure catapulting (LMPC) for live cell isolation. But LMPC requires complex manipulations and some skill. Furthermore, single-cell cloning using laser microdissection has not yet been demonstrated. The first evidence of successful application of laser microdissection with gravity transfer (LMDGT) for capturing and recultivation of live cells is presented. A new strategy for LMDGT is presented because of the failure to reproduce the manufacturer’s protocol. Using the new strategy, successful capturing and recultivation of circle-shaped samples from confluent monolayer of HeLa cells was demonstrated. It was found that LMDGT is easier than LMPC because it doesn’t require personal participation of investigator in transferring of isolated samples to final culture dishes. Moreover, for the first time, the generation of clonal colonies from single live cells isolated by laser microdissection was demonstrated. Data obtained in this study confirm that LMDGT is a reliable and high-yield method allowing isolation and expansion of both cell clusters and single cells from adherent cell cultures.
