Y-27632也同等有效抑制ROCK-II。
Y-27632作用于PKC, cAMP依赖的蛋白激酶和肌球蛋白轻链激酶(MLCK)几乎没有活性,K分别为26 μM, 25 μM, 和 > 250 μM。
Y-27632通过选择性抑制Ca敏感化,而抑制多种兴奋剂而不是KCl,包括Phenylephrine, Histamine, Acetylcholine, Serotonin, Endothelin,和Thromboxane诱导的平滑肌收缩,IC50为0.3-1 μM。
实验操作来自于公开的文献,仅供参考细胞实验细胞系cyES cells方法For 5-bromo-2′-deoxyuridine (BrdU) incorporation assays, dissociated cyES cells were seeded at a concentration of 500 cells/cm2 onto fresh feeder layers in the presence of the ROCK inhibitors Y-27632 (Wako Pure Chemical Industries, Tokyo, Japan) or Fasudil(Tocris Bioscience, MO, USA) during the first 24 h of culture. The BrdU incorporation assay was performed using colorimetric BrdUCell proliferation Kit (Roche Diagnostics) according to the manufacturer's instructions. BrdU incorporations were also observed byimmunocytochemical (ICC) staining with BrdU Labeling and Detection Kit I (Roche Diagnostics).浓度0, 0.1, 0.5, 5, 10, 20µM处理时间24 h动物实验动物模型EAC modeling配制dissolved in 0.9% NaCl剂量0.1, 1, 10 mg/kg/day for 14 days给药处理i.p.不同实验动物依据体表面积的等效剂量转换表(数据来源于FDA指南)小鼠大鼠兔豚鼠仓鼠狗重量 (kg)0.020.15 1.80.40.0810体表面积 (m)0.0070.0250.150.050.020.5K系数36128520动物 A (mg/kg) = 动物 B (mg/kg) ×动物 B的K系数动物 A的K系数例如,依据体表面积折算法,将白藜芦醇用于小鼠的剂量22.4 mg/kg 换算成大鼠的剂量,需要将22.4 mg/kg 乘以小鼠的K系数(3),再除以大鼠的K系数(6),得到白藜芦醇用于大鼠的等效剂量为11.2 mg/kg。
AbMole科研快报-从临床样本中产生肺腺癌类器官的方案
AbMole精研抑制剂十年,最新的科研动态不断与您分享。
本期与您分享的是:从临床样本中产生肺腺癌类器官的方案。
人类癌症组织衍生的类器官可维持其亲本肿瘤的突变谱和组织学特征,从而为预测患者对抗癌药物的反应提供了平台。
在这里,我们提供了一个完整详细的分步方案,从原发性肿瘤组织中衍生出肺腺癌类器官。
使用我们的协议,可以产生成功率达80%的类器官系。
Y-27632(Abmole,M1817,纯度99.63%)被用于组织培养(10 μM)。
将组织与5 mL TrypLE Express + Y-27632二盐酸盐(10 mM)在37°C的振荡平台上孵育10分钟。
要注意Y-27632二盐酸盐已添加到消化培养基和培养基中,以防止解离引起的阳极氧化,但应在培养的第一周后从类器官培养基中撤除。

【AbMole科研快报】通过干细胞微腔阵列中的聚集实现高通量自动化类器官培养AbMole精研抑制剂十年,最新的科研动态不断与您分享。
本期与您分享的是:通过干细胞微腔阵列中的聚集实现高通量自动化类器官培养干细胞衍生的上皮样器官通常被用于组织的生物和生物医学建模。
然而,固体细胞外基质中干细胞培养的复杂性、缺乏标准化和质量控制阻碍了类器官在工业规模上的常规应用。
本项研究报道了微工程细胞培养设备的制造和悬浮培养的可扩展和自动化方法,以及在聚合物-水凝胶基质内的微腔阵列中捕获的数千个单个胃肠道类有机物的实时分析,研究人员在小鼠和人类胃肠道类器官中发现了:固体基质的缺乏大大降低了类器官的异质性。
使用该设备筛选患者源性结直肠癌类器官的抗癌候选药物,并基于图像的表型分析来揭示药物作用机制。
可扩展的类器官培养技术有望促进其在药物开发和诊断中的使用。
