Cancer stem cells (CSCs) escape from 5-aminolevulinic acid (5-ALA)-based photodynamic detection (PDD) (upper panel). An iron chelator deferoxamine (DFO) enhances accumulation in CSCs of PpIX from 5-ALA, which will facilitate the elimination …more Japanese researchers identify process to improve fluorescence detection of cancer stem cells, which are primarily responsible for brain tumor progression and recurrence...
