Cytori Cell Therapy

Cytori Cell Therapy is for investigational use in the United States.


Cytori is developing cell therapies that harness the unique attributes of living cells that are present in an adult human patient’s own adipose (fat) tissue, also known as Adipose-Derived Regenerative Cells (ADRCs). Cytori Cell Therapy is the collective name given to the fresh, heterogeneous population of ADRCs prepared with the proprietary Celution® System platform technology and administered to a patient for a specific disease or medical condition, all within a single day:

Cytori Cell Therapy is designed to repair injured tissue, preserve function, improve quality of life, and modify disease progression.


Physicians and scientists have demonstrated the frequency of stem cells in adipose (fat) tissue to be 2,500 times greater than the frequency of similar cells in bone marrow.1,2,3 Further, adipose (fat) tissue can be more easily collected than bone marrow via a small volume liposuction procedure.

Since Cytori technology prepares ADRCs exclusively from an adult human patient’s own adipose (fat) tissue, treatment with these cells avoids common transplantation issues, such as cell rejection or disease transmission, and does not require anti-rejection or immunosuppressant drugs.


While the exact mechanism of action is unknown, pre-clinical publications suggest the use of ADRCs has been associated with improvements in angiogenesis, inflammation, and fibrosis.


In pre-clinical studies, ADRCs have been shown to promote angiogenesis, or the creation of new blood vessels from pre-existing vessels. Application of these cells has also been associated with improvement of vasomotor function.4,5,6,7,8


In pre-clinical studies, use of ADRCs has been shown to be associated with modulation of inflammation through expression of factors that regulate both pro- and anti-inflammatory cells. This includes processes such as polarization of macrophages and inhibition of T cell activation.6,9,10,11,12

Fibrosis/Wound Repair

In pre-clinical studies use of ADRCs has been associated with reduction and remodeling of fibrosis. This is mediated by modulation of expression of extracellular matrix components and remodeling enzymes.5,13,14

Cytori Cell Therapy is a novel approach that has the potential to harness the power of a patient’s own cells to promote healing.


Cytori Cell Therapy is comprised of an autologous, heterogeneous, readily accessible cell population that is the result of more than a decade of rigorous research and development. 15,16,17,18,19


Advanced Technology, Convenient For the Patient

Cytori Cell Therapy is being developed to be delivered in a single treatment, designed to avoid the need for frequent re-treatment.


Same-Day Cell Therapy

Cytori Cell Therapy eliminates the requirement for cells to be shipped to off-site facilities. Cells can be harvested in the hospital and processed on-site for faster care.


Safety Profile

The use of ADRCs in pre-clinical and clinical studies has been shown to be well-tolerated. Hundreds of patients have been treated with ADRCs in multiple clinical trials across the world. Cytori’s approach to cell therapy avoids the risk of rejection.
