Isolating Osteoblasts or Osteoclasts from bone

I am looking for a protocol that would allow me to isolate both mature
osteoblasts and osteoclasts from mice bone (not the marrow).

I need to avoid cell culture altogether.

I've heard something about mincing up the bone (from which marrow has
been removed), treating it with collagenase to release cells, and then
using density gradient centrifugation on percoll gradients.  Does
anybody have any information on a more specific protocol, and the kinds
of results I might expect to get.

Additionally, has anyone used any other methods like Magnetic beads to
increase the purity?
