Three Things to Know about the Cell Cycle: Interphase consists of three stages: G1 (first gap phase), S (synthesis, in which DNA replication occurs), and G2 (second gap phase). LCM can isolate homogeneous populations of normal or tumor cells, potentially resolving tissue into single cells (Assersohn et at., 2002; Emmert-Buck et at., 1996).
