COVID-19 studies are our top priority. For all other trials, there is a 4-week delay in processing a trial submitted to the ANZCTR and additional delays for updates of registered trials. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Interventional
Description of intervention(s) / exposure
This study will be carried out on 30 samples of umbilical cord blood. Each sample of cord blood will be collected from the placenta using a special collection bag containing anticoagulant (citrate phosphate dextrose adinine).

The samples will be divided into three groups:

1. 10 samples of the cord blood from which stem cells will be separated by density gradient separation using ficoll hypaque. This method is performed by centrifugation of a suspension of the cord blood mixed with ficoll-paque followed by isolation of mononuclear cells.

2. 10 samples of the cord blood from which stem cells will be separated by automated processing and harvesting system using AXP autoexpress - Thermogenesis. Cord blood is transferred into the processing bagset which is placed in the AXP device and then centrifuged. During centrifugation, component stratification and separation occurs.

3. 10 samples of the cord blood from which stem cells will be separated by magnetic bead separation system using MACS Columns and MACS Separators. That depends on labeling CD34+ cells with CD34 microbeads then, the cell suspension is loaded onto a MACS Column which is placed in the magnetic field of a MACS Separator. After removing the column from the magnetic field, the magnetically retained CD34+ cells can be eluted as the positively selected cell fraction.

Comparator / control treatment
Data from the 30 samples will be plotted to compare the three stem cell separation methods from umbilical cord blood to each other.
Control group
Active

Outcomes
Primary outcome [1] 291100 0
After sample stem cell separation, it will be followed by calculation of the harvested stem cells to define the stem cell separation method with the best outcome of highest stem cell count.
Timepoint [1] 291100 0
The primary outcome (stem cell count) is assessed in the same day of sample collection from the umbilical cord and stem cell separation from it using each method separately.
Secondary outcome [1] 306002 0
None
Timepoint [1] 306002 0
None
