Gene expression profiling of cells isolated ex vivo is a unique tool to assess gene expression in vivo. Exemplified for CD4+CD45RO+ effector/memory T helper (T E/M) lymphocytes of human peripheral blood, we have analyzed different isolation procedures and storage conditions for the introduction of bias.
Unbiased transcriptomes of resting human CD4⁺ CD45RO⁺ T lymphocytes.

View SamplesTo compare human memory CD4+ T cell subsets in peripheral blood (PB) and bone marrow (BM) of healthy individuals at transcriptional level, we analyzed the global gene expression of ex vivo PB CD69- as well as BM CD69- and CD69+ memory CD4+ T cells from 4 paired PB and BM samples. The gene expression of these subsets was additionally compared to the transcriptional profile of 8 PB samples taken ex vivo or stimulated with phorbol myristate acetate (PMA) and Ionomycin for 3 hours.
Human memory T cells from the bone marrow are resting and maintain long-lasting systemic memory.

View SamplesWe profile the cell line expression of 279 circRNAs, that are highly expressed across 457 bladder cancer patient samples. Additionally, we investigate their cellular location in fractionated cell lines Overall design: 9 bladder cancer cell lines and 3 fractionated bladder cancer cell lines
Circular RNA expression is abundant and correlated to aggressiveness in early-stage bladder cancer.
