title: Research advance in effects of weightlessness or simulated weightlessness on tumor cells.
abstract: Weightless environment is a rare phenomenon on the ground where the interactions among cells and internal cellular structures disappear or become weakened. Studies on the biological features and molecular expression of tumors cells in weightlessness condition may provide new clues to the tumor initiation, process, diagnosis, and therapy.
