Intrapancreatic transplantation of cell progeny after expansion of ALDHhi cells with or without BMS493 shows no reduction of hyperglycemia in Streptozotocin-treated NOD/SCID mice. Thus, Umbilical cord blood (UCB)-derived ALDHhi cells effectively lost islet regenerative capacity during ex vivo expansion[1].
In Vitro
BMS493 (100 nM; 6 days; ALDHhi UCB cells) treatment shows a twofold increase in the number of ALDHhi cells available for transplantation compared with untreated controls. Newly expanded ALDHhi cells shows increased numbers of CD34 and CD133-positive cells, as well as a reduction in CD38 expression, a marker of hematopoietic cell differentiation[1]. Cell Viability Assay[1] Cell Line: ALDHhi UCB cells Concentration: 100 nM Incubation Time: 6 days Result: Showed a twofold increase in the number of ALDHhi cells available for transplantation compared with untreated controls.
