Stem Cell therapy cures uncureable disease...?

Hello friends....

I do not know where the most relevant place to post this is:

Dana white (millionaire fight promoter) goes to Germany, syas he goes through a minor surgery and cures himself of a debilitating disease that western docs couldn't cure...

Can anyone explain the Science behind this stuff or validate it?

THANKS!!
