What's the difference between ossification and osteogen?
Ossification
Definition:
(n.) The formation of bone; the process, in the growth of an animal, by which inorganic material (mainly lime salts) is deposited in cartilage or membrane, forming bony tissue; ostosis.
(n.) The state of being changed into a bony substance; also, a mass or point of ossified tissue.

Osteogen
Definition:
(n.) The soft tissue, or substance, which, in developing bone, ultimately undergoes ossification.
