"muscle stem cells" which would be more appropriate if what one wants to do is
produce muscle tissue for consumption. So there is some lack of accuracy
but perhaps not completely out of line since the general reading public knows
what "stem cells" are but probably don't know what "satellite cells" or
"myoblasts" are. (This problem will not be solved until everyone has a
hardwired (implanted) brain-to-web link with the first two options on the
"lookup menu" for unfamiliar words being Wikipedia and Google. I'd have
PubMed probably as #3 but your choices may vary.)<BR></DIV><BR>

<DIV><FONT face=Arial size=2>The OCR text in your link is scrambled. It
has, for instance, as units of length ( "run", and ~Lm)

up reading </FONT></DIV>
