Project description:The kidney is the main hematopoietic organ in teleost fish. Various stages of hematopoietic cells were observed in the interstitial tissue of the kidney. We recently demonstrated that zebrafish hematopoietic stem cells (HSCs) expressing jam1a were specifically localized along the renal collecting ducts in the adult kidney. Interestingly, most of HSCs invaded into the intracellular spaces of the epithelium in collecting ducts, suggesting that collecting ducts provide a specific microenvironment for HSCs. In order to identify niche factors in collecting ducts, we performed microarray analysis in collecting ducts isolated from the Tg(jam1a:EGFP) zebrafish kidney. Collecting ducts were isolated from Tg(jam1a:EGFP) zebrafish under a fluorescent microscope. To examine the effect of X-ray irradiation on the niche, collecting ducts were isolated from the fish irradiated with 25Gy. The whole kidney tissues were also used for a comparison analysis. Two independent replicates consisting of five zebrafish were prepared for each sample.

Project description:RNAseq was performed on hcar1-4+/+ and hcar1-4-/- zebrafish larvae with (2 h and 4 h) or without (0 h) Pseudomonas aeruginosa (PA) ear infection. The transcriptome profile generated here reveals PA14 infection-induced differential gene expression patterns between hcar1-4-/- and hcar1-4+/+ siblings.
