| contents | In single-cell RNA sequencing (scRNA-seq) analysis, a key challenge is inferring hidden cellular dynamics from static cell snapshots. Various computational methods have been developed to address this, focusing on perspectives like pseudotime trajectories, RNA velocities, and estimating the differentiation potential of cells, often referred to as "cell potency." This review summarizes 14 methods for defining cell potency from scRNA-seq data, categorizing them into average-based, entropy-based, and correlation-based methods based on how they summarize gene expression levels into a potency measure. We highlight the key similarities and differences within and between these categories, offering a high-level intuition for each method. Additionally, we use unified mathematical notations to detail each method's methodology and summarize their usage complexities, including parameters, required inputs, and differences between published descriptions and software implementations. We conclude that cell potency estimation remains an open question without a consensus on the optimal approach, emphasizing the need for benchmark datasets and studies. This review aims to provide a foundation for future benchmark studies, while also addressing the broader challenge of comparing methods that infer cellular dynamics from scRNA-seq data through various perspectives, including pseudotime trajectories, RNA velocities, and cell potency. |
