Abstract

As an important breakthrough in the field of life science in recent years, single-cell sequencing technology provides unprecedented resolution for the analysis of cell heterogeneity and complex biological processes. While traditional bulk sequencing methods are limited by their inability to distinguish differences between cells, single-cell sequencing can reveal gene ex pression characteristics and functional status at the level of individual cells, thereby more accurately mapping the cell map. The purpose of this study is to systematically explore the analytical method of single cell sequencing data and its application prospects in the fields of biology and medicine. This fr amework shows significant advantages in cell type identification, developmental trajectory inference, and disease marker screening. In addition, we also verified the practical application value of this method in the analysis of tumor heterogeneity and the dynamic monitoring of immune cells. This study not only provides an innovative solution for the analysis of single-cell sequencing data, but also lays a foundation for further exploration of the molecular mechanism of complex diseases, showing its broad prospects in precision medicine and regenerative medicine.
