Chondroblasts create bone. Chondrocytes are matrue chondroblasts. The chondroblasts become chondrocytes once they enter lacunae and are surrounded by intercellular substance.
The cartilage doesn't turn into bone, the cartilage dies because it's extracellular matrix calcifies. Osteoblasts come in after to clear out the dead cartilage and create new bone. Just a clarification.
Mike I think you might mean "Osteoclasts". Since they release powerful lysosomal enzymes and acids they can breakdown bone. This process is called "resorption". This is a normal part of development , maintenance, and repair of bone.
Thanks!

Does phosphate and hydroxyapatite have to do with the ossification too of cartilage?

ok, so please help, trying to patch the gaps here.
1. reserve cartilage is made up of chondroblasts, but is there still a perichondrium?
2. proliferative cartilage is mitotically active chondroblasts forming cytes to enter the lacunae?
3. the hypertrophy layer is cytes? is that their only function? That they are now mature cells?
4. dark staining = osteogenic?
5. what is the zone of destruction/erosion? is this where osteoclasts are? why is it important? Thank you!

Don't chondroCLASTS clear away the GAG and proteoglycans from the old cartilage?
