[Histonet] size of pancreas beta cells on a mouse

[Diana McCaig]

Hi
I know this is a bit off topic but I had a  co-workers daughter ask me
to find the size of a beta cell of the pancreas on a mouse.  I work in a
hospital environment and do not have access to information on mice.  It
is for a school project.  She claims she can not find the size on the
internet.  I would appreciate it if someone in research could provide me
the information.
sincere thanks
Diana
