Stem Cells are the foundation from which all parts of the human body grow. There are, however, significant differences in types of stem cells.

Types of Stem Cells

Learn about different types of stem cells.

Fat Derived Stem Cells

(Method used by IMAC Regeneration Centers)


  • Obtained by a mini-liposuction under local anesthesia.
  • Contains predominantly stem cells that grow into vessels and structural tissues such as bones, cartilage, muscles, nerves and organs.
  • Fat derived stem cells have approximately 50 times more structural building stem cells than bone marrow derived cells.
  • Fat derived cells have a much lower concentration of white blood cells, so less inflammation when injected into the body.
  • Studies have shown that fat derived stem cells can regrow cartilage must faster in joints, probably due to a much higher level of cartilage building stem cells present.
Bone Marrow Derived Stem Cells
  • Obtained from a bone marrow biopsy typically from the pelvis.
  • Contains stem cells that can grow into red and white blood cells, as well as some cells that can grow into blood vessels and structural tissues such as bones, cartilage, muscles, nerves and organs.
  • Originally used for bone marrow transplants to replenish red and white blood cells after chemotherapy.
  • Bone marrow cells have a higher white blood cell count which will lead to more inflammation when injected into tissues and joints.
  • Bone marrow cells have a lower concentration of cells to repair structural tissues.
Amniotic Stem Cells
  • Obtained from amniotic fluid surrounding a fetus.
  • Very few of the cells in amniotic fluid are stem cells.
  • These cells are then dehydrated and sterilized with radiation.
  • No living stem cells survive this process.
  • Any benefit from amniotic stem cells is from possible growth factors left over from the dead stem cells.
