Further study details as provided by Ohio State University:

Primary Outcome Measures:
  • Gene expression profiles [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
    determined using gene chip. This yields data in the form of relative rates of gene expression.

Secondary Outcome Measures:
  • Gene chip findings. [ Time Frame: 1 year or more. ] [ Designated as safety issue: No ]
    Gene chip findings healing verses non healing wounds.

Biospecimen Retention:   Samples With DNA

Healing verses non-healing

Detailed Description:

A single subject will provide 2 tissue samples from a single wound over a 4 week time period and the samples will be categorized as healing versus non-healing responses on the basis of decreased (healing) or increased (non-healing) wound area measurements over the 4-week time period. A chronic wound generally is a wound which shows no signs of significant healing in four weeks or has not healed in eight weeks.


Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Sampling Method:   Probability Sample
Study Population

Patients who have chronic wound, wound should be 4 week or more in one place with out heal.

  • ii.Informed consent obtained from patient by designated study nurse

Exclusion Criteria:

  • i. can't provide informed consent
  • ii. therapeutically anticoagulated
  • iii. pregnant females ( > 30 days since 1st day of last menstrual period)
