The objective of this study was to determine whether single-cell RNA sequencing (scRNA-seq) or single-nucleus RNA sequencing (snRNA-seq) was more effective for studying the goat pancreas. Pancreas tissues from three healthy 10-day-old female were processed into single-cell and single-nucleus suspensions. These suspensions were then used to compare cellular composition and gene expression levels following library construction and sequencing. Both scRNA-seq and snRNA-seq were eligible for primary analysis but produced different cell identification profiles in pancreatic tissue. Both methods successfully annotated pancreatic acinar cells, ductal cells, alpha cells, beta cells, and endothelial cells. However, pancreatic stellate cells, immune cells, and delta cells were uniquely annotated by scRNA-seq, while pancreatic stem cells were uniquely identified by snRNA-seq. Furthermore, the genes related to digestive enzymes showed a higher expression in scRNA-seq than in snRNA-seq. In the present study, scRNA-seq detected a great diversity of pancreatic cell types and was more effective in profiling key genes than snRNA-seq, demonstrating that scRNA-seq was better suited for studying the goat pancreas. However, the choice between scRNA-seq and snRNA-seq should consider the sample compatibility, technical differences, and experimental objectives.
本研究的目的是确定单细胞RNA测序(scRNA-seq)或单细胞核RNA测序(snRNA-seq)在研究山羊胰腺方面是否更有效。将三只健康的10日龄雌性山羊的胰腺组织处理成单细胞和单细胞核悬液。然后,在构建文库和测序后,利用这些悬液比较细胞组成和基因表达水平。scRNA-seq和snRNA-seq都适用于初步分析,但在胰腺组织中产生了不同的细胞鉴定图谱。两种方法都成功注释了胰腺腺泡细胞、导管细胞、α细胞、β细胞和内皮细胞。然而,胰腺星状细胞、免疫细胞和δ细胞仅通过scRNA-seq得到注释,而胰腺干细胞仅通过snRNA-seq得到鉴定。此外,与消化酶相关的基因在scRNA-seq中的表达高于snRNA-seq。在本研究中,scRNA-seq检测到了多种胰腺细胞类型,并且在分析关键基因方面比snRNA-seq更有效,表明scRNA-seq更适合研究山羊胰腺。然而,在scRNA-seq和snRNA-seq之间进行选择时,应考虑样本兼容性、技术差异和实验目的。
