• 产品描述： WS3, a β cell proliferation inducer, regulates Erb3 binding protein-1 (EBP1) and the IκB kinase pathway

• 靶点： EGFR;IκB/IKK

• 体外研究： WS3 induces pancreatic R7T1 β cell proliferation in dose response, with an EC50 value of 0.28 μM.
  WS3 (1.0 nM-1.0 µM) reversibly proliferate primary retinal pigment epithelial (RPE) cells isolated from fetal and adult human donors. Following withdrawal of WS3, RPE cells differentiate into a functional monolayer, as exhibited by their expression of mature RPE genes and phagocytosis of photoreceptor outer segments.

• 体内研究： 在小鼠β细胞系R7T1中,WS3诱导细胞增殖（EC50=0.074 μM）。在原代胚胎和成人视网膜色素上皮细胞中,WS3可逆诱导细胞发生增殖

• 细胞实验： R7T1 cells are growth-arrested by removal of doxycycline for 2 days and plated into 384-well plates at a density of 3,000 cells/well in growth medium. Β cell proliferation is assessed using CellTiter Glo after 4 days. Fold increase in cell number is calculated by normalizing compound-treated wells to the median of DMSO-treated wells.
