## Abstract

Described herein are cell-free therapeutic compositions derived from blood or plasma and uses thereof for the treatment of selected diseases and disorders.

## Claims

### Claim 1

A method of treating a disease or disorder in a subject in need thereof, the method comprising:
administering to the subject having the disease or disorder a therapeutically effective amount of a composition comprising:
blood-derived nanoparticles, the blood-derived nanoparticles having a diameter less than 200 nm, the blood-derived nanoparticles derived from substantially platelet-free and cell-free blood, and
a concentration of blood-derived nanoparticles in the composition being at least 1×108 nanoparticles/ml.

### Claim 2 (depends on 1)

The method of claim 1, wherein the composition is made by a process comprising:
(a) obtaining a volume of blood;
(b) centrifuging the volume of blood at 2,000×g for at least 10 minutes (min) to obtain a first supernatant;
(c) centrifuging the first supernatant at 100,000×g for at least 90 min to obtain a pellet comprising the nanoparticles;
(d) isolating and resuspending the pellet in a volume of resuspension fluid to obtain a resuspended volume; and
(e) filtering at least a portion of the resuspended volume using a 0.22 uM filter.

### Claim 3 (depends on 1)

The method of claim 1, wherein the composition is made by a process comprising:
(a) obtaining a volume of blood;
(b) centrifuging the volume of blood at 2,000×g for at least 10 minutes (min) to obtain a first supernatant;
(c) centrifuging the first supernatant at 2,000×g for at least 5 min to obtain a second supernatant;
(d) centrifuging the second supernatant at 100,000×g for at least 90 min to obtain a pellet comprising the nanoparticles;
(e) isolating and resuspending the pellet in a volume of resuspension fluid to obtain a resuspended volume; and
(f) filtering at least a portion of the resuspended volume using a 0.22 uM filter.

### Claim 4 (depends on 1)

The method of claim 1, wherein the disease or disorder is joint pain.
