Project description:Stress induces undifferentiated stem cells to differentiate in a way that looks like normal differentiation; We used hyperosmolar stress as a generic, energy-depleting stressor and tested for the global changes in the transcriptional response of placental trophoblast stem cells Experiment Overall Design: Placental trophoblast stem cells were subjected to 0, 0.5, 2, 6, and 24 hours of hyperosmolar stress and then assayed by Affymetrix 430MOE V2 whole mouse genome arrays.

Project description:A transcriptome study in mouse hematopoietic stem cells was performed using a sensitive SAGE method, in an attempt to detect medium and low abundant transcripts expressed in these cells. Among a total of 31,380 unique transcript, 17,326 (55%) known genes were detected, 14,054 (45%) low-copy transcripts that have no matches to currently known genes. 3,899 (23%) were alternatively spliced transcripts of the known genes and 3,754 (22%) represent anti-sense transcripts from known genes.
