<span>When a bone breaks your body immediately begins working to heal it. Within the first hours of a fracture a blood clot forms around the break and special cells call phagocytes begin cleaning germs from the bone fragments. Then, a soft callus composed of collagen is created around the break. Next, a hard callus forms as osteoblast cells work to create new bone to aid in the reconstruction process. After all is said and done the bone is remodeled by cells called osteoclasts. The bone will be completely rebuilt in 3-9 years.</span>

We use cell membranes to treat disease because the cell membrane is one of the main barriers that pathogens need to overcome, hindering their replication.
<h3>What is the cell membrane?</h3>
The cell membrane is a thin lipoprotein film formed by phospholipids and proteins delimiting the cytoplasm of all types of cells. They prevent invading microorganisms from attaching to the cell and replicating.
Then, using the concepts of cell membrane, we can use them to prevent viral diseases from occurring since the virus cannot fix itself to replicate. So in this case, the cell membrane is one of the main barriers that pathogens need to overcome, hindering their replication.
