Tissue Injuries

Our body has a fantastic ability to heal itself! But some injuries are more than the body can handle. Doctors and scientists are working on regenerative medicine to help speed the body's natural healing ability.

Injuries and Healing

When areas of tissue in the body are damaged or destroyed, the body tries to replace them with new tissue by producing cells capable of creating new tissue. 

When a tissue like bone is broken, both its cells and its blood vessels may be injured. The body is prepared to heal minor injuries like these, so when trauma occurs the body works to stop any blood letting by clotting, and then starts producing new cells to replace the damaged ones. These new cells are produced in several places in the body, the main one being the marrow in the center of the bone.  They travel through the body to the damage site and become new tissue. Also, the body builds new thin blood vessels, called capillaries, to bring nutrients and oxygen to the new cells. 

When the damage is too extensive and there is a big gap of missing or dead tissue where no capillaries survive, new cells can’t come fill the area because there is no blood reaching them with nutrients and oxygen. Some tissues like the bone and the skin are easier to heal than others. Other tissues in the body, such as skin and heart muscle, can't heal as well and form scars in the places where they were mended.

When the body can't heal the tissue well, it forms scar tissue which is a weaker and more disorganized tissue than the healthy one.

This is where Regenerative Medicine steps in!...
The basic principles are supplying new cells with STEM CELLS and providing structure with SCAFFOLDS!!!
