Project description:Triplicate pairwise comparsion of FACS sorted GFP+ve Vs GFP-ve cells from the kidneys of the HoxB7-GFP transgenic mice on compugen 22K mouse arrays. HoxB7-GFP mice express GFP in the ureteric tree and its derivatives while the metanephric mesenchyme, interstitium, developing vasculature etc do not. Keywords: repeat sample

Project description:The long term objective is to create an encyclopedia of the expression levels of all genes in multiple components of the developing kidney. The central thesis is straightforward. The combination of fluorescent activated cell sorting (FACS) plus microarray analysis offers a powerful, efficient and effective method for the creation of a global gene expression atlas of the developing kidney. Microarrays with essentially complete genome coverage can be used to quantitate expression levels of every gene in FACS isolated components of the developing kidney. The ensuing rapid read-out provides an expression atlas that is more sensitive, more economical and more complete than would be possible by in situ hybridizations alone. HoxB7-GFP transgenic mice were utilized to isolate the ureteric duct cells from E10.5 embryonic kidneys. The ureteric duct cells were isolated from embryos using microdissection, trypsin treatment and FACS. The RNA was isolated from purified ureteric duct cells and the gene expression profiles were determined by microarrays.

The RNA was isolated from purified ureteric bud cells and the gene expression profiles were determined by microarrays.
Project description:Morphogenesis of cellecting duct system within developing mouse kidney is driven by growth at the tips of ureteric epithelium. To characterize the transcription program within the tip compartment, here we performed mRNA-Seq of tip cells (Wnt11RFP+;Hoxb7+ cells) and stalk cells (Wnt11RFP-;Hoxb7GFP+ cells) obtained from mouse embryonic kidney through FACS. We identified tip-specific genes from these data, and verified with in situ hybridization and followed up with mechanistic study for some of the intersting targets.
Project description:We generated a murine genetic model of beta-catenin deficiency targeted to the ureteric bud cell lineage to study the role of beta-catenin mediated Wnt signaling during ureteric morphogenesis. Experiment Overall Design: A comparison was made between triplicate samples of E12.5 kidneys from either normal mice or mice with a b-catenin allele containing LoxP sites flanking exons 2 through 6 crossed to Hoxb7-Cre:Gfp mice
