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.

Is stem cell therapy safe and effective?
Some bone, skin and corneal (eye) injuries and diseases can be treated by grafting or implanting tissues, and the healing process relies on stem cells within this implanted tissue. These
procedures are widely accepted as safe and effective by the medical community
.

What is the average cost of stem cell therapy? The average cost of stem cell therapy ranges from
under $5,000 to over $25,000
, depending the type and sources of the stem cells, the patient’s medical condition, and the number of treatments required.

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.
