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:Identification of differentially expressed genes in intestinal phagocytes, compared to non-intestinal cells in Schmidtea mediterranea.
Project description:We used Nimblegen arrays with design 2007-11-06_Smed_ESTs_4_exp to measure changes in gene expression during a timecourse of regeneration of one side of the head in Schmidtea mediterranea flatworms. Following amputation of one side of the head, samples were collected from both the regeneration blastema and non-regenerating side of the head on days 2, 3, and 4 post-amputation. Gene expression in these samples was compared to that in non-regenerating control samples collected at the time of amputation.
