Researchers are designing ‘dancing’ molecule meant to make it easier for cartilage damaged by osteoarthritis to regenerate. Image credit: adamkaz/Getty Images.
There isn't a version of that with cartilage replacement or regeneration, but then now imagine that pothole gets deeper and deeper so you get past the asphalt down into the dirt.
They reported a case study in which a full-thickness defect in the articular cartilage of a human knee was successfully repaired. [23] While the use of cultured mesenchymal stem cells has shown promising results, a more recent study using uncultured MSC's has resulted in full-thickness, histologically confirmed hyaline cartilage regrowth.
The process of the entire regeneration of the bone can depend on the angle of dislocation or fracture. While the bone formation usually spans the entire duration of the healing process, in some instances, bone marrow within the fracture has healed two or fewer weeks before the final remodelling phase.

Since articular cartilage does not have a blood supply and chondrocytes (cells in articular cartilage) have limited mobility, the articular cartilage has very limited ability to heal itself. If left untreated, the cartilage lesions will gradually worsen and the grade of the lesion or defect will increase. [5]
Because mesenchymal stem cells may regenerate cartilage, cartilage growth in human knees using autologous cultured mesenchymal stem cells is under research and preliminary clinical use, and appears to be safe as of 2016. [11] An advantage to this approach is that a person's own stem cells are used, avoiding tissue rejection by the immune system ...
Therefore, the ability to naturally regenerate the heart would have an enormous impact on modern healthcare. However, while several animals can regenerate heart damage (e.g. the axolotl), mammalian cardiomyocytes (heart muscle cells) cannot proliferate (multiply) and heart damage causes scarring and fibrosis.

The use of fish skin with its natural constituent of omega 3, has been developed by an Icelandic company Kereceis. [50] Omega 3 is a natural anti-inflammatory, and the fish skin material acts as a scaffold for cell regeneration. [51] [52] In 2016 their product Omega3 Wound was approved by the FDA for the treatment of chronic wounds and burns. [51]
