Regenerative cells are specific types of cells that can be activated in order to restore organs and tissues back to a pre-existing normal state.
- Stem cells are specific cells capable of generating new specialized types of cells, thereby allowing the regeneration of damaged tissues.
- For example, hematopoietic stem cells can be used to generate new red blood cells whose function is to transport oxygen in the bloodstream.
- Regenerative cells can be used in tissue engineering in order to restore the function and structure of damaged organs.
In conclusion, regenerative cells are specific types of cells that can be activated in order to restore organs and tissues back to a pre-existing normal state.

The rotator cuff tendons enclose the shoulder joint on all sides except on the bottom side, which partly explains the nature of most shoulder dislocations.
Rotator cuffs are a type of tendons that surround the shoulder and help in keeping the upper arm in its location and also attached to the shoulder joint. The upper arm is connected at the socket of the shoulder.
Shoulder dislocation is the injury where the upper arm is dislocated from its exact location of the socket of shoulder joint. This can also cause damage to the ligaments. Shoulder dislocation can be of three types: anterior, posterior and inferior.
