Mapping the mouse developmental and aging atlas by single cell mRNA-seq

ABSTRACT: Single-cell mRNA sequencing (mRNA-seq) technologies are reshaping the current cell-type classification system. In previous studies, we built a comprehensive mouse cell atlas to catalog all cell types by collecting scRNA-seq data in the fetal and adult stages. Howerver, systematically study for organism-level dynamic changes of cellular states across mouse life span are still lacking. Here, We made an updated version of mouse cell atlas (MCA) by adding scRNA-seq data covering 14 major mouse organs during different mouse development period. We revealed aging related regulatory networks and pathways that have not been well characterized previously. We found that the expressions of immune-related genes, such as antigen-presenting genes and immunoglobulin genes, appeared in non-immune cell types in aging process. We also focused on the expression of lung epithelial immunoglobulin genes and revealed their related transcriptional regulation mechanisms. The updated MCA resource provides a valuable resource for studying mammalian development, maturation and aging.

Mapping the Drosophila developmental and aging atlas by single cell mRNA-seq

Project description:Single-cell mRNA sequencing (scRNA-seq) technologies are reshaping current cell-type classification system. In previous studies, we constructed the Mouse Cell Atlas (MCA) and Human Cell Landscape (HCL) to catalog all cell types by collecting scRNA-seq data. Howerver, the systematic study for organism-level dynamic changes of cellular states across fruit fly (Drosophila melanogaster) life span are still lacking. Here, we constructed the Drosophila cell Landscape covering different development periods using Microwell-seq protocol. The Drosophila cell landscape provides a valuable resource for studying cross-sepciess development, maturation and aging.

Mapping Mouse Cell Atlas by Microwell-seq

Project description:We developed Microwell-seq, a high-throughput and low-cost scRNA-seq platform using simple, inexpensive devices. Using Microwell-seq, we constructed a basic scheme for the Mouse Cell Atlas. We reveal single cell hierarchy for many tissues that have not been well previously characterized. Our study demonstrates the wide applicability of the Microwell-seq technology and the Mouse Cell Atlas resource.

scRNA-seq of sea lamprey (Petromyzon marinus) brain regions

Project description:scRNA-seq was used in order to produce a cell type atlas of the larval and adult sea lamprey (Petromyzon marinus) brain. This resource enabled us to reveal the cell type composition and molecular organization of a representative of a lineage (i.e., the cyclostomes) that diverged from the rest of vertebrates around 500 million years ago, and lays the foundations for a better comprehension of vertebrate brain evolution

Aging-associated alterations in mammary epithelia and stroma revealed by single-cell RNA sequencing

Project description:Aging of the mammary gland is closely associated with increased susceptibility to breast cancer, yet there have been limited systematic studies of aging-induced alterations within this organ. Here we leveraged the power of high-throughput single-cell RNA-sequencing (scRNA-seq) to generate a detailed transcriptomic atlas of young and aged murine mammary tissues, including both epithelial and stromal cell types. This analysis identified altered proportions and distinct gene expression patterns in multiple cell populations as a consequence of aging, independent of history of pregnancy and hormone cycle. In addition, we detected a rare luminal cell type that expresses both hormone-sensing and alveolar lineage markers as well as a unique gene expression signature. In addition, these cells exhibit a significant decrease in relative abundance with age. Overall, this high-resolution transcriptomic landscape reveals the effects of aging on normal mammary gland physiology and can serve as a valuable resource for understanding aging-associated susceptibility to breast cancer.
