产品描述 | Thiazovivin, a ROCK inhibitor (IC50: 0.5 μM), increases the survival rate of hESC. |
靶点活性 | ROCK:~0.5 μM (cell free) |
体外活性 | 当细胞在E-cadherin阻断抗体的存在下培养时,细胞在Thiazovivin处理后形成的大型、紧密的聚集体严重受阻,且观察到广泛的细胞死亡。Thiazovivin(2 μM)抑制ROCK活性,并在与Y-27632(10 μM)相似的水平上保护hESCs,后者是一种广泛使用的选择性ROCK抑制剂[1]。在Thiazovivin处理组中,囊胚和胚胎细胞团在给养细胞上的附着率高于对照组。Thiazovivin处理增加了OCT4和NANOG基因的多能性标记以及粘附分子E-cadherin[2]。通过在重编程培养中添加Thiazovivin,CB细胞的重编程效率增加了10倍以上[3]。 |
激酶实验 | Synthesis of compound immobilized affinity matrixes: Compounds Tzv and its inactive analog (10 mg each) in DMSO (500 μL) and Et3N (10.4 μL) were added to Reacti-Gel (0.5 mL, 25 μmol) that was washed by DMSO in an Eppendorf vial. The reaction mixture was incubated at room temperature until the starting material disappeared (determined by HPLC). After the disappearance of the starting material, ethanolamine (15 μL) was added and the resulting mixture was incubated at room temperature overnight to block the Reacti-Gel. The resulting affinity matrices were washed thoroughly with DMSO (500 μL × 4), PBS (500 μL × 2), and stored at 4 °C in NaN3 solution (0.1% in PBS). Affinity pull-down was performed as described previously. Briefly, whole cell lysates were pretreated with the unfunctionalized affinity matrix at 4 °C for 1.5 h. After washing three times, samples were incubated with the positive or negative affinity matrix at 4 °C for 1 h. After heat shock, samples were loaded and separated on a 4–20% Tris-Glycine SDS PAGE and silver stained with a Silver Stain Plus Kit. The differentially retained protein bands were cut, destained, and analyzed with LCMS [1]. |
细胞实验 | Chemically defined and feeder-free human embryonic stem cell (hESC) culture was described briefly as following. hESCs were grown on Matrigel-coated tissue culture plates in N2B27-CDM [DMEM-F12 supplemented with 1× N2 supplements, 1× B27 supplements, 2 mM L glutamine, 0.11 mM 2-mercaptoethanol, 1× nonessential amino acids, and 0.5 mg/mL BSA (fraction V)] and 20 ng/mL bFGF. Human ESCs were passaged every five to six days with 0.05% trypsin. Murine ESCs are cultured in knockout DMEM supplement with 2 mM L glutamine, 1× nonessential amino acids, 15% serum replacement, and 1 × 10^3 ng/mL leukemia inhibitory factor (LIF). For clonal survival assays, single hESCs were diluted to clonal density and plated onto 96-well Matrigel-coated plate. For low-density survival assays, 500 cells were plated onto 96-well Matrigel-coated plate. To visualize hESC colonies, cultures were fixed in 4% paraformaldehyde in phosphate buffered saline (PBS) for 5 min, washed once in PBS, then stained for alkaline phosphatase (ALP) activity as described in the manufacturer's instructions. ALP-positive colonies were counted on an inverted microscope. For growing hESCs in mouse medium, HES2, HUES7, HUES9, and HUES1-Oct4-GFP were cultured in murine ESC (mESC) growth media supplemented with 1-μM mitogen-activated protein kinase/extracellular signal-regulated kinase kinase (MEK) inhibitor PD0325901 and 5-μM p38 inhibitor SB202190 and 1 × 10^3 human LIF [1]. |
