Project description:The freshwater planarian Schmidtea mediterranea is well known by its amazing regeneration capabilities thanks to the presence of adult stem cells, the neoblasts, the only proliferative cells and responsible for the differentiation in all the cell types of the organism. This study involves the creation of separated transcript libraries from both, isolated neoblasts and differentiated cells, as well as their posterior sequencing and quantification through Digital Gene Expression (DGE) for the characterization of the neoblast transcriptome. Three DGE libraries were produced from FACS isolated cell populations X1 (proliferating stem cells, S/G2/M), X2 (a mix of proliferating stem cells and stem cell progeny, G0/G1) and Xin (differentiated cells, G0/G1). Cells were isolated from a pool of 32 regenerating animals two days after being cut off pre- and post-pharingeally to trigger regeneration and neoblast proliferation.

Project description:10X genomics single cell analysis of yHSC vs oHSC from Gfplc3/Gfplc3 mice with index sorted SMART-Seq2 sequencing to map AThi oHSC vs ATlo oHSC based on GFP-LC3 marker levels. 10X Genomics data harmonized by nearest neighbor integration and uniform manifold approximation and projection (UMAP) representation distinguished yHSC from oHSC, with the largest transcriptional differences observed in the G0/G1 cell cycle phase cluster. Within oHSCs, AThi oHSCs were almost exclusively observed in the G0/G1 cluster, whereas ATlo oHSCs were spread across the activation continuum, with cells still in the G0/G1 cluster found more proximal to S cluster cells.
Project description:Sexual Schmidtea mediterranea Trunk Regeneration. Sexual biotype Schmidtea mediterranea trunk fragments were sequenced at 0 day, 3 day, 5 day and 7 day post amputation along with whole worm juvenile animals in order identify sexual specific transcripts. Juvenile worms lack sex organs, testes and ovaries present in D0 trunk fragments. Days 3-7 represent time points of degeneration and regeneration of the sexual organs, testes and ovaries.

Project description:The transcriptome of the planarian Schmidtea mediterranea is not well characterized. We have used RNA-Seq to characterize the transcriptome in both sexual and asexual strains of S. mediterranea from both untreated and irradiated animals. Moreover, we have performed RNA-Seq on RNA purified from FACS sorted neoblasts and differentiated cells. Together these studies expand our understanding of the planarian transcriptome and have identified strain-specific, neoblast-specific, and conserved transcripts. RNA-Seq was performed on RNA isolated from untreated and irradiated S. mediterranea animals from both the sexual and asexual strains, on FACS purified X1 neoblasts, X2 neoblasts, and Xins differentiated cells. One of the raw data files for GSM847465 is missing. The fasta file is provided at http://genome.vcell.uchc.edu/GenomeData02/Graveley_Lab_Public_Data/Planarian/S.mediterranea_SexNIRmRNA3.fa.gz
