Biological Activity
BMS-204493(BMS493) is an inverse pan-retinoic acid receptor (RAR) agonist. BMS493 increases nuclear corepressor interaction with RARs. BMS493 also could prevent retinoic acid-induced differentiation[1][2].
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.
In Vivo
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].
