## Abstract

The present invention provides compositions and formulations of micronized Wharton's jelly having a controlled viscosity such that when delivered to the injured region of a subject, it remains substantially localized with little or no migration out of the injured region for the repair and/or regeneration thereof. Micronized Wharton's Jelly can be suspended in a pharmaceutically acceptable aqueous carrier, such as saline, sterile water, or any suitable buffer, to form a suspension or a gelatinous gel composition, or it can be in the form of a paste, suitable for delivery into the space adjacent the articular surface cartilage injured region of a subject. The micronized Wharton's jelly when employed at sufficient concentrations can be hydrated into a gel or paste and administered topically, or it can be injected into the body through the use of a needle and syringe. Accordingly, micronized Wharton's Jelly, compositions, or formulations thereof, can be delivered in a manner that is more convenient than Wharton's jelly that has not been micronized in accordance with the present invention.

## Claims

### Claim 1

A method for inducing hyaline cartilage formation in a patient in need thereof, said method comprising introducing a composition comprising Wharton's jelly including one or more growth factors found in Wharton's jelly into a joint of said patient, wherein said composition is substantially free of umbilical cord tissue.

### Claim 2 (depends on 1)

The method of claim 1, wherein the growth factor is selected from the group consisting of fibroblast growth factor (FGF), insulin-like growth factor I (IGF-I), transforming growth factor beta (TGF-beta), platelet-derived growth factor (PDGF), and epidermal growth factor (EGF).

### Claim 3 (depends on 1)

The method of claim 1, wherein the composition further comprises a pharmaceutically acceptable carrier.

### Claim 4 (depends on 3)

The method of claim 3, wherein the pharmaceutically acceptable carrier is selected from the group consisting of water, saline, and phosphate buffered saline.

### Claim 5 (depends on 1)

The method of claim 1, wherein the composition further comprises a surfactant or an emulsifier.

### Claim 6 (depends on 1)

The method of claim 1, wherein the composition further comprises a plasticizer.

### Claim 7 (depends on 1)

The method of claim 1, wherein the composition is injectable.

### Claim 8 (depends on 7)

The method of claim 7, wherein the injectable composition further comprises one or more of an osmotic agent, a hydrophobic agent, and a surface active agent.

### Claim 9 (depends on 1)

The method of claim 1, wherein the composition is a liquid, a gel or a paste.

### Claim 10 (depends on 1)

The method of claim 1, wherein the composition further comprises a biocompatible polymer.

### Claim 11 (depends on 10)

The method of claim 10, wherein the biocompatible polymer is a plasticizer.

### Claim 12 (depends on 11)

The method of claim 11, wherein the plasticizer is cross-linked with a biocompatible cross-linking agent.

### Claim 13 (depends on 1)

The method of claim 1, wherein the composition further comprises amniotic membrane of an umbilical cord.

### Claim 14 (depends on 1)

The method of claim 1, wherein the composition is substantially free of amniotic membrane of an umbilical cord.

### Claim 15 (depends on 1)

The method of claim 1, wherein said patient suffers from an articular surface defect.

### Claim 16 (depends on 15)

The method of claim 15, wherein the articular surface defect is localized at a joint of shoulder, elbows, knee, hip, feet, ankle, hand, and/or wrist of said patient.

### Claim 17 (depends on 16)

The method of claim 16, wherein the composition is administered to the site of the articular surface defect.

### Claim 18 (depends on 1)

The method of claim 1, wherein the composition is administered to the patient during a micro-fracture procedure.

### Claim 19 (depends on 1)

The method of claim 1, wherein the composition is administered to a drill fracture site during a micro-fracture procedure.

### Claim 20 (depends on 1)

The method of claim 1, wherein the composition is added to an autogenous bone tissue.

### Claim 21 (depends on 1)

The method of claim 1, wherein the composition is administered to a synovial joint of said patient.

### Claim 22 (depends on 1)

The method of claim 1, wherein the Wharton's jelly is micronized.
