What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Autologous Stem Cell TransplantationBiological
Autologous bone marrow aspiration (20 ml) from iliac crest. Separation of mononuclear cells using ficoll hypaque and culture in 10% fetal bovine serum and Dulbecco modified eagles medium. After confluent stage, detachment of cells with trypsin/EDTA, and subculture. Repeated passages until obtainment of required cell number. Confluent cells of last passage are washed with tyrode solution and incubate with M199 for 60 minutes. Cells are separated using trypsin/EDTA and washed 3 times with M199 and 1% HSA. Precipitate will be diluted with heparinized M199 to make solution with 6×106 cells /ml. Sample will be tested for viability and detection of CD45, CD34, CD90, CD44, CD13, CD105, and CD166 before injection. The number of cells for injection will be between 20-25 million cells; in a maximum volume of 4-6 ml. Cells will be injected in the knee joint with a 21 gauge needle.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Autologous Stem Cell Transplantation in people with Knee Osteoarthritis, run by Tehran University of Medical Sciences at 1 site in Iran.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 22 Nov 2010. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Iran. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
1- Comparison of pain in the injected knee with the controlateral knee 2- Comparison of joint motion of the injected knee with the controlateral knee (time frame: 12 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00550524, which also lists 6 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Nov 2010; AzTrials last refreshed its copy on 8 Nov 2026.
