Trapping prostate cancer cells to keep them from spreading provides hope

When prostate cancer stem cells (CSCs) were enclosed in self-assembling nanomaterials made of peptides (SAP), the SAP stopped cancer stem cell colony formation and also stopped the division of cancer cells in laboratory cultures (in vitro). According to the international team of researchers who built and tested the nano-sized traps and published their results in a recent issue of Cell Transplantation (20:1), which is freely available on-line, the cancer cells grew and multiplied after they were "liberated" from their SAP prisons.
