E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The objective of the trial is to examine whether enrichment of a fat graft with autologous ASC injected into the breast tissue using traditional technique of ‘small aliquot-injection’ will significantly improve take of the graft and the result of a breast augmentation. The trial will compare fat grafting enriched with ex vivo expanded stem cells to the conventional fat grafting. |
Formålet med studiet er at undersøge hvorvidt berigelse af et fedttransplantat med opformerede autologe adipøst-deriverede stamceller øger overlevelsen af et fedttransplantat efter injektion i et underudviklet bryst. Hvis dette viser sig at være tilfældet forventes det, at resultaterne at kan anvendes til at forbedre den aktuelle behandling af patienter med tidligere brystkræft. |
|
E.2.2 | Secondary objectives of the trial |
Screening of radiological changes in the breast after conventional and stem cell-enriched fat injection as based on MRI and mammography. |
