As per a conference being held in Japan, it has been revealed that patients undergoing stem cell trial has shown some improvement. The research was being started in November 2010 and by a group of researchers from the Southern General Hospital, Glasgow.

The study researchers were of the view that it will be too early to confirm that improvement in patients' health is due to the clinical trial. One of the striking features of the study is that all men are taking part in the study, and that too those, who are above 60 years of age.

The trial has been started with an aim that stem cell treatment is able to provide second life to people, who have been affected by damaged brain tissues. The trial is expected to bring movements among patients.

Prof Keith Muir, who is actively involved in the research and is from Glasgow University, was of the view that they are not super-excited about the news and take it as normal news and not a dramatic one.

"We've been able to do with the technology is to grow cells from the original sample such that we don't have to source any further tissue", said Muir. He further affirmed that it will take another five years to predict the result.
