Tumours Spark Stem-cell Review

摘要

A report claiming that unregulated transplants of human fetal neural stem cells led to tumours in a boy's brain and spinal cord is being hotly discussed by stem-cell researchers. Although the procedure took place well outside the scientific mainstream, it underscores the need for caution as clinical trials involving stem-cell transplantation move forward.rn"This is the first documented case of tumours resulting from fetal-cell transplant," says Wise Young, a neurosurgeon at Rutgers University in Piscataway, New Jersey.
