1.Introduction Recent advances in single-cell RNA sequencing(scRNA-seq)have enabled the study of how individual cells respond to various external perturbations such as drug stimulation at gene expression level[1..Precisely inferring perturbation responses allows us to explore how and why individual tumor cells evade cancer treatment,greatly advancing personalized medicine research and deepening our understanding of biological mechanisms[2].However,considering the high costs of sequencing and the complexity of obtaining perturbed samples,utilizing computational methods to predict cellular responses to perturbations holds great potential[2].
