Summary of immunochemical staining of the different tissue types in negative control group, positive control group and fibrous tissue with Collagen I and Collagen II
| Tissue type | Coll I | Coll II | ||||
|---|---|---|---|---|---|---|
| Bone | Cartilage | Fibrous tissue | Bone | Cartilage | Fibrous tissue | |
| Negative control | + | − | + | −/+ | +++ | + |
| Positive control | + | − | nm | − | +++ | nm |
| Periosteum flap | + | − | ++ | −/+ | +++ | ++ |
The original cartilage as well as the neo-cartilage show characteristic positive results for Coll II, but not for Coll I, which is slightly expressed in bone and strong in fibrous tissue (nm: non-measurable, as there is no fibrous tissue located in the positive control sections). Please see also the pictures (Figure5).
