Abstract

Chinese hamster ovary (CHO) cells play an important role in the biopharmaceutical industry, but their production efficiency requires enhancement to meet the growing market demands. Artificial intelligence (AI) has been a potent tool for modeling bioprocesses to support biopharmaceutical manufacturing. However, existing AI models do not adapt well to process data collected at irregular time intervals and have limited capability to scale up and down to incorporate various process parameters. To address the limitations, this study develops a novel neural ordinary differential equation (ODE) model for predicting key variables such as viable cell concentration, glucose concentration, lactate concentration, pH, and dissolved oxygen in a CHO cell bioreactor. Validated through extensive bioreactor experiments, the neural ODE model shows a better accuracy compared to the benchmark models, which include a conventional mechanistic model and a hybrid model. Additionally, the neural ODE model incorporated essential process variables that were not considered in the previous models. It successfully extrapolates to predict unknown dynamics at different initial conditions, which showcases robust adaptability. Moreover, the model provides useful insights into the relationship among variables, highlighting its potential for bioprocess modeling.

预测中国仓鼠卵巢细胞在生物反应器系统中生长的神经常微分方程模型
中国仓鼠卵巢(CHO)细胞在生物制药行业中发挥着重要作用,但其生产效率需要提高才能满足日益增长的市场需求。人工智能(AI)一直是建立生物过程模型以支持生物制药生产的有效工具。然而,现有的人工智能模型并不能很好地适应以不规则时间间隔收集的工艺数据,并且在纳入各种工艺参数方面的放大和缩小能力有限。为了解决这些局限性,本研究开发了一种新型神经常微分方程(ODE)模型,用于预测 CHO 细胞生物反应器中的存活细胞浓度、葡萄糖浓度、乳酸浓度、pH 值和溶解氧等关键变量。通过大量的生物反应器实验验证,神经 ODE 模型与基准模型(包括传统机械模型和混合模型)相比显示出更高的准确性。此外,神经 ODE 模型还纳入了以往模型未考虑的基本过程变量。它成功地推断预测了不同初始条件下的未知动态,展示了强大的适应性。此外,该模型对变量之间的关系提供了有用的见解,突出了其在生物过程建模方面的潜力。
