MSC (mesenchymal stem cells) can potentially restore the bone marrow microenvironment and aid recovery after hematopoietic stem cell transplantation by successfully migrating through bone marrow endothelium.
The study involved in vitro assays to examine MSC's ability to invade and migrate through the endothelium, highlighting the role of MMP-2 in this process.
Results showed that higher cell density in cultures increased the production of TIMP-3, which inhibits MSC migration, suggesting that growth conditions directly affect their extravasation capacity.
