About this study

Official title: Ex Vivo Expansion of Umbilical Cord Blood Using a Unique Bio-system

By doing this study, researchers hope to develop a special technique and laboratory conditions to help support umbilical stem cell growth and multiplication.

In this project, researchers propose a three dimensional (3D) microenvironment that mimics the bone marrow stem cell microenvironment, with its supporting cells of osteoblasts and stromal cells. In theory, this will result in better expansion of cord blood stem cells ex vivo.

Read the detailed description

To successfully expand umbilical cord blood stem cells ex vivo, a microenvironment that resembles the stem cell microenvironment, or stem cell 'niche' should be created. In designing this bio-system, we make use of several observations. First, bone osteoblasts are important in promoting hematopoietic stem cell expansion, accordingly, this bio-system will ensure the physical proximity of the cord blood stem cells to a 3D bone tissue derived from mesenchymal stem cells (MSCs). These MSCs will be isolated from Wharton's jelly, and by using an osteogenic medium and special scaffolds, these MSCs will differentiate into osteogenic progenitors creating a 3D bone structure. The other observation is that, co-culture of cord blood stem cells with mesenchymal stem cells is superior to liquid cultures in terms of ex vivo expansion , accordingly, in this experiment, undifferentiated MSCs will be co-cultured with cord blood stem cells in this created 3D bone structure. This is a unique design that has the potential to expand cord blood stem cells more efficiently.

Questions about this trial

What is this clinical trial studying?

An observational study of Pregnancy, run by University of Kansas at 1 site in United States.

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: finished, as of the sponsor's last update on 3 Jan 2013. 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 United States. 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.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

bio-system for ex-vivo expansion of umbilical cord blood stem cells (time frame: one year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 3 Jan 2013.
