What are the limitations of stem cell therapy?
Even though cells have the chemical capacity to detect damaged tissue, there might be a physical obstruction (like a blocked artery) that will not allow these stem cells to “travel” to damaged areas. If the cause of the obstruction is not eradicated, there will be poor, slow, or no tissue regeneration.

What are two disadvantages of using stem cells?
A disadvantage of most adult stem cells is that they are pre-specialized , for instance, blood stem cells make only blood, and brain stem cells make only brain cells. These are derived from embryos that are not a patient’s own and the patient’s body may reject them.
Which is better PRP or stem cell therapy?
For example, if tissue around joints needs to be rejuvenated or infused with healthy cells, stem cell therapy may be the better option. However, if you have soft tissues that are healing slowly, PRP may be the recommended treatment.
