体外心血管疾病模型需要重现组织规模的功能,以提供体内相关性。我们已经开发了一种新的方法来测量工程心血管平滑肌和横纹肌在体外电刺激和药物刺激过程中的收缩性。我们提出了一个基于生长理论的有限弹性分析计算的收缩应力的二维各向异性肌肉组织培养在一个灵活的合成聚合物薄膜。用新生大鼠心室肌细胞构建的心肌在收缩峰值时以0.5 Hz起搏,产生9.2 ± 3.5 kPa的应力,与成年大鼠乳头肌收缩力的测量结果相似。用人脐动脉平滑肌细胞工程化的血管组织维持13.1 ± 2.1 kPa的基础收缩张力,并且当用内皮素-1刺激时产生另外5.1 ± 0.8 kPa。这些数据表明,这种方法可能是有用的,在评估药物对心血管组织的疗效和安全性。
In vitro cardiovascular disease models need to recapitulate tissue-scale function in order to provide in vivo relevance. We have developed a new method for measuring the contractility of engineered cardiovascular smooth and striated muscle in vitro during electrical and pharmacological stimulation. We present a growth theory-based finite elasticity analysis for calculating the contractile stresses of a 2D anisotropic muscle tissue cultured on a flexible synthetic polymer thin film. Cardiac muscle engineered with neonatal rat ventricular myocytes and paced at 0.5 Hz generated stresses of 9.2 ± 3.5 kPa at peak systole, similar to measurements of the contractility of papillary muscle from adult rats. Vascular tissue engineered with human umbilical arterial smooth muscle cells maintained a basal contractile tone of 13.1 ± 2.1 kPa and generated another 5.1 ± 0.8 kPa when stimulated with endothelin-1. These data suggest that this method may be useful in assessing the efficacy and safety of pharmacological agents on cardiovascular tissue.
