Project description:Insights into many biological phenomena requires knowing the temporal order of cellular events, which is traditionally achieved through continuous direct observations [1, 2]. An alternative solution leverages irreversible genetic changes, such as naturally occurring mutations, to create indelible markers that enables retrospective temporal ordering [3-8]. Using Native sgRNA Capture and sequencing (NSC-seq), a newly devised and validated multi-purpose single-cell CRISPR platform, we developed a molecular clock approach to record the timing of cellular events and clonality in vivo while incorporating cell state and lineage information. Using this approach, we uncovered precise timing of tissue-specific cell expansion during murine embryonic development, unconventional developmental relationships between cell types, and new epithelial progenitor states by their unique genetic histories. NSC-seq analysis of murine adenomas coupled to multi-omic and single-cell profiling of human precancers, with clonal analysis of 418 human polyps, demonstrated the occurrence of polyancestral initiation in 15-30% of colonic precancers, revealing their origins from multiple normal founders. Our study presents a multimodal framework that lays the foundation for in vivo recording, integrating synthetic or natural indelible genetic changes with single-cell analyses to explore the origins and timing of development and tumorigenesis in mammalian systems.

Project description:The mechanism underlying the cervical carcinogenesis mediated by persistent HPV infection remains elusive. Here we pioneeringly deciphered both temporal transition and spatial distribution of the cellular subsets during the disease progression from normal cervix, precancer lesions to cervical cancer by integrating scRNA-seq with ST. We not only identified three ‘HPV-related epithelial clusters’ unique to normal, HSIL and cervical cancer respectively, but also discovered node genes which potentially determined the disease progression. Moreover, we observed a gradual transition of multiple immune cells from positive immune response to dysregulation and exhaustion, to an immune-suppressive microenvironment during the malignant program. Besides, the cellular interaction analysis further verified a ‘homeostasis-balance-malignancy’ change within cervix microenvironment during disease escalation. Together, these findings not only deciphered mysterious persistent HPV infection spatiotemporally from the process of precancer to cervical cancer but also provided unprecedented possibilities for accurate diagnosis, precise treatment and prognosis evaluation for precancer and cervical cancer.

Project description:Gene Expression profiles of sorted CD66High and CD66Low cells were generated from CIN612-9E cells grown in Emedia. We have analyzed the gene expression pattern of CD66High and CD66Low cells from CIN612 9E. These cells are derived from a cervical precancer lesion (M. Bedell, J. Hudson, T. Golub et al, 1991, J. Virol) Two sets of experiments (biological replicates) were performed for CD66High and CD66Low cells.
