Adipose Tissue


Adipose tissue is a heterogeneous biological tissue composed of various cellular components; it provides clinicians with a stem-cell-rich product in the form of a 3D scaffold.1,2

The Composition of Adipose Tissue3



Mesenchymal stem cells (MSCs) Endothelial cells Pericytes Pre-adipocytes Adipocytes Hematopoietic-lineage cells

Mesenchymal stem cells (MSCs)4

Capable of differentiating into many different cell types responsible for the repair or growth of bone, cartilage, muscle, tendons, ligaments and connective tissue.

Endothelial cells

Structural components of blood vessels. They are also key players in angiogenesis (vascular cell growth).

Pericytes

Wrap around the endothelial cells of capillaries and blood vessels. They play a critical role in supporting the survival of endothelial cells and the overall process of angiogenesis.

Pre-adipocytes

Progenitor cells that are able to adopt the adipocyte cell fate.

Adipocytes

Store lipids to provide energy.

Hematopoietic-lineage cells

Includes red blood cells, white blood cells and platelets.

The Benefits of Concentrating


Concentrated adipose tissue provides a physical scaffold of multiple cellular components.
The benefits of concentrated adipose tissue include:
  • Excellent natural scaffold
  • High concentration of MSCs
  • Minimally invasive process for the removal and collection of stem cells (compared to removal of bone marrow)

Removal of Excess Infranatant Fluid

Excess infranatant fluid in a graft sample makes it challenging to estimate an accurate graft volume for a procedure, because this fluid is resorbed by the body. In an attempt to account for resorption, physicians typically overfill the treatment site with lipoaspirate, resulting in increased swelling and an undesirable initial aesthetic result.5,6 Removal of excess fluid can minimize the need for overfilling and offer a more predictable aesthetic outcome.7

Removal of Excess Oils and Lipids

Oils, lipids and cellular debris that are present in lipoaspirate may cause an inflammatory response that prolongs graft healing and can prove toxic to the cellular components of the graft itself. Removal of these materials may promote graft survival.5,7


Adipose Tissue Is Getting Noticed

After the recent discovery of adipose tissue's stem-cell-rich nature, concentrated adipose tissue is being used in orthopedic applications for osteoarthritis.8,9

Risk Information: These procedures require needle access, possibly resulting in discomfort, tenderness, bruising, swelling, bleeding or pain at the access site, at which there is a small risk of infection. Lightheadedness, fainting, nausea or vomiting may occur. Before any medical procedure, review prescription and nonprescription medications and any natural or herbal remedies your patient is taking or plans to take.
