  • Be \>70 and \< 85 years of age at the time of signing the Informed Consent Form.
  • Have a Canadian Study on Health and Aging (CSHA) Clinical Frailty Scale score of 5 "mildly frail" or 6 "moderately frail".
  • Have a 6 minute walk distance of \> 200m and \< 400 m. Distances of two 6MWTs are to be within 15% of each other.
  • Have a serum TNF-alpha level \> 2.5 pg/mL

You may not qualify if:

  • Be unwilling or unable to perform any of the assessments required by the protocol.
  • Have a diagnosis of any disabling neurologic disorder, including, but not limited to, Parkinson's disease, Amyotrophic Lateral Sclerosis, multiple sclerosis, cerebrovascular accident with residual deficits (e.g., muscle weakness or gait disorder), or diagnosis of dementia.
  • Have a score of 24 or lower on the Mini Mental State Examination (MMSE)
  • Have poorly controlled blood glucose levels (HbA1c \>8.0%).
  • Have a clinical history of malignancy within 2.5 years (i.e., subjects with prior malignancy must be cancer free for 2.5 years) except curatively-treated basal cell carcinoma, melanoma in situ or cervical carcinoma.
  • Have any condition that in the opinion of the Principal Investigator limits lifespan to \< 1 year.
  • Have autoimmune disease (e.g. rheumatoid arthritis, systemic lupus erythematosus).
  • Be using chronic immunosuppressant therapy such as high-dose corticosteroids or TNF-alpha antagonists (prednisone use at doses of \< 5 mg daily is allowed).
  • Test positive for hepatitis B virus
  • a. If the subject tests positive for anti-hepatitis B core antigen (HBc) or anti-HBs, they must be currently receiving treatment for Hepatitis B prior to infusion and remain on treatment throughout the study.
  • Test positive for verimic Hepatitis C virus, HIV1/2, or syphilis
  • Have a resting blood oxygen saturation of \<93% (measured by pulse oximetry).
  • Known or suspected alcohol or drug abuse within three years preceding Screening
  • Have a known hypersensitivity to dimethyl sulfoxide (DMSO).
  • Be an organ transplant recipient (other than transplantation for corneal, bone, skin, ligament, or tendon).
  • +17 more criteria
