Regenerative Medicine Q&A

What is regenerative medicine?

Regenerative medicine uses cells found in various areas of your body that regenerate into just about any other type of cell. They are like “blank slates,” meaning stem cells don’t contain a specific type of DNA. Stem cells and PRP enhance healing by regenerating cells near areas of damaged tissue and enhancing your body’s natural ability to heal itself.

Where do stem cells come from?

Stem cells are found throughout the human body. Your provider harvests them from one or more of the following areas:

  • Bone marrow
  • Blood
  • Brain tissue
  • Muscle tissue
  • Other organs
  • Placental tissue
  • Umbilical cord tissue

Stem cells are sourced from your body or donated placental or umbilical cord tissue from healthy pregnancies. Donated stem cells are tested for quality and purity. However, you might feel at ease knowing stem cells used for your therapy are your own. Your doctor lets you know which type of stem cells are right for you.

Where is PRP sourced from?

Your provider obtains PRP, or platelet-rich plasma, from your own blood. They take a small blood sample from your arm, spin it in a centrifuge, and isolate platelets containing special healing capabilities from the plasma. 

What is regenerative medicine used for?

Your doctor uses regenerative medicine to treat various diseases, injuries, and chronic pain. Examples include:

  • Arthritis pain
  • Joint problems
  • Degenerative joint disease
  • Temporomandibular joint (TMJ) disorders
  • Bone fractures
  • Ligament and muscle injuries
  • Damaged cartilage
  • Other sports-related injuries

Injecting stem cells or PRP into injured areas helps repair tissue, reduce inflammation, and stimulate blood flow. It also facilitates healing, improves mobility, restores numerous body functions, and relieves pain.

What should I expect during treatment?

After sourcing PRP from your blood or stem cells from donated tissue or cells within your body, your provider injects stem cells or PRP into injured areas, diseased tissue, or painful joints to accelerate healing and regenerate new tissue. 

You notice beneficial effects from regenerative medicine over time, and your provider might recommend a series of treatments to help you achieve optimal results.

Don’t let an injury or pain sideline you from being active or enjoying life to its fullest. Schedule an appointment with Pain Care Providers over the phone or online today.
