Errors in stem cell division can give rise to tumours. By studying stem cells in the fruit fly, scientists at the Institute for Research in Biomedicine (IRB Barcelona) have identified one of the mechanisms that govern how these cells divide. The study appears this week in the scientific journal Developmental Cell.

Stem cells have the extraordinary capacity to divide producing two very distinct cells: one retains stem cell identity and continues to undergo asymmetric division, while the ...

Due to a lack of suitable studies, it is unclear whether patients with soft tissue sarcoma can benefit from autologous haematopoietic stem cell transplantation. With this type of therapy, some of the patient's own (autologous) stem cells are removed at a convenient time and generally re-implanted after a course of high-dose chemotherapy. At present, there is neither indication nor proof of additional benefit compared to conventional chemotherapy. Owing to current gaps in knowledge, autologous s...
