WebJul 21, 2024 · Extracorporeal fucosylation of CD44 on rabbit marrow MSCs has been found to increase their homing ability through CXCL12 and S1P regulation. 122 Specific … WebThus, uPAR appears to regulate BM homing and α4-β1 dependent retention of transplantable BMCs, possibly HSC/HPCs. If uPAR mediates retention of HSC/HPCs, then this signal should be inactivated upon mobilization. Indeed, in 5-FU or G-CSF-treated WT mice, we found increased uPAR cleavage, and elevated levels of soluble uPAR (suPAR) …
