Immunogen: recombinant protein Podocalyxin, a sialoglycoprotein, is thought to be the major constituent of the glycocalyx of podocytes. It is a member of the CD34 family of trans- membrane sialomucins. It is involved in the regulation of both adhesion and cell morphology and cancer progression. It functions as an anti-adhesive molecule that maintains an open filtration pathway between neighboring foot processes in the podocyte by charge repulsion. Podocalyxin acts as a Description: pro-adhesive molecule, enhancing the adherence of cells to immobilized ligands, increasing the rate of migration and cell-cell contacts in an integ- rin-dependent manner. Sialylated, O-glycosylated glycoforms of podocalyxin expressed by colon carcinoma cells possess L-selectin and E-selectin binding activity, and may be pivotal to the metastatic spread of colon carcinoma cells.

Glomerular development has been analyzed mainly in mice, whereas analysis of human kidney development has been minimal because of limited access to embryonic kidneys. We previously reported the induction of three-dimensional primordial glomeruli from human induced pluripotent stem (iPS) cells. Here, using transcription activator–like effector nuclease-mediated homologous recombination, we generated human iPS cell lines that express green fluorescent protein (GFP) in the NPHS1 locus, which encodes nephrin, and we show that GFP expression facilitated accurate visualization of nephrin-positive podocyte formation in

  • Human Transcription Factors Responsive to Initial Reprogramming Predominantly Undergo Legitimate Reprogramming During Fbroblast Conversion to Ipscs Ricardo R
    www.nature.com/scientificreports OPEN Human transcription factors responsive to initial reprogramming predominantly undergo legitimate reprogramming during fbroblast conversion to iPSCs Ricardo R. Cevallos1, Yvonne J. K. Edwards1,2, John M. Parant3, Bradley K. Yoder2 & Kejin Hu1* The four transcription factors OCT4, SOX2, KLF4, and MYC (OSKM) together can convert human fbroblasts to induced pluripotent stem cells (iPSCs). It is, however, perplexing that they can do so only for a rare population of the starting cells with a long latency. Transcription factors (TFs) defne identities of both the starting fbroblasts and the end product, iPSCs, and are also of paramount importance for the reprogramming process. It is critical to upregulate or activate the iPSC-enriched TFs while downregulate or silence the fbroblast-enriched TFs. This report explores the initial TF responses to OSKM as the molecular underpinnings for both the potency aspects and the limitation sides of the OSKM reprogramming. The authors frst defned the TF reprogramome, i.e., the full complement of TFs to be reprogrammed. Most TFs were resistant to OSKM reprogramming at the initial stages, an observation consistent with the inefciency and long latency of iPSC reprogramming. Surprisingly, the current analyses also revealed that most of the TFs (at least 83 genes) that did respond to OSKM induction underwent legitimate reprogramming. The initial legitimate transcriptional responses of TFs to OSKM reprogramming were also observed in the reprogramming fbroblasts from a diferent individual. Such early biased legitimate reprogramming of the responsive TFs aligns well with the robustness aspect of the otherwise inefcient and stochastic OSKM reprogramming. OCT4, SOX2, KLF4, and MYC (collectively OSKM) can convert human fbroblasts into induced pluripotent stem cells (iPSCs), which are the man-made version of embryonic stem cells (ESCs)1–3.

Here, we report that nephric duct, ureteric bud, and collecting duct epithelia express high levels of grainyhead-like homolog 2 (Grhl2) and that nephric duct lumen expansion is defective in Grhl2-deficient mice. In collecting duct epithelial cells, Grhl2 inactivation impaired epithelial barrier formation and inhibited lumen expansion. Molecular analyses showed that GRHL2 acts as a transcrip- tional activator and strongly associates with histone H3 lysine 4 trimethylation. Integrating genome-wide GRHL2 binding as well as H3 lysine 4 trimethylation chromatin immunoprecipitation sequencing and gene expression data allowed us to derive a high-confidence GRHL2 target set. GRHL2 transactivated a group of genes including Ovol2, encoding the ovo-like 2 zinc finger transcription factor, as well as E-cadherin, claudin 4 (Cldn4), and the small GTPase Rab25. Ovol2 induction alone was sufficient to bypass the requirement of Grhl2 for E-cadherin, Cldn4,andRab25 expression. Re-expression of either Ovol2 or a combination of Cldn4 and Rab25 was sufficient to rescue lumen expansion and barrier formation in Grhl2-deficient collecting duct cells.

This capacity has largely been ascribed to paracrine factors secreted by nerve-resident Schwann cells. Here, we used single-cell transcriptional profiling to identify ligands made by different injured rodent nerve cell types and have combined this with cell-surface mass spectrometry to computationally model potential paracrine interactions with peripheral neurons. These analyses show that peripheral nerves make many ligands predicted to act on peripheral and CNS neurons, in- cluding known and previously uncharacterized ligands. While Schwann cells are an important ligand source within injured nerves, more than half of the predicted ligands are made by nerve-resident mesenchymal cells, including the endoneurial cells most closely associated with peripheral axons. At least three of these mesen- chymal ligands, ANGPT1, CCL11, and VEGFC, promote growth when locally applied on sympathetic axons.

  • Rab35 Gtpase Couples Cell Division with Initiation of Epithelial Apico-Basal Polarity and Lumen Opening
    ARTICLE Received 3 Sep 2015 | Accepted 25 Feb 2016 | Published 4 Apr 2016 DOI: 10.1038/ncomms11166 OPEN Rab35 GTPase couples cell division with initiation of epithelial apico-basal polarity and lumen opening Kerstin Klinkert1,2,3, Murielle Rocancourt1,2, Anne Houdusse4 & Arnaud Echard1,2 Establishment and maintenance of apico-basal polarity in epithelial organs must be tightly coupled with cell division, but the underlying molecular mechanisms are largely unknown. Using 3D cultures of renal MDCK cells (cysts), we found that the Rab35 GTPase plays a crucial role in polarity initiation and apical lumen positioning during the first cell division of cyst development. At the molecular level, Rab35 physically couples cytokinesis with the initiation of apico-basal polarity by tethering intracellular vesicles containing key apical determinants at the cleavage site. These vesicles transport aPKC, Cdc42, Crumbs3 and the lumen-promoting factor Podocalyxin, and are tethered through a direct interaction between Rab35 and the cytoplasmic tail of Podocalyxin. Consequently, Rab35 inactivation leads to complete inversion of apico-basal polarity in 3D cysts. This novel and unconventional mode of Rab-dependent vesicle targeting provides a simple mechanism for triggering both initiation of apico-basal polarity and lumen opening at the centre of cysts. 1 Membrane Traffic and Cell Division Lab, Cell Biology and Infection Department, Institut Pasteur, 25–28 rue du Dr Roux, 75724 Paris, France. 2 Centre National de la Recherche Scientifique UMR3691, 75015 Paris, France. 3 Sorbonne Universite´s, Universite´ Pierre et Marie Curie, Universite´ Paris 06, Institut de formation doctorale, 75252 Paris, France. 4 Institut Curie, Structural Motility Lab, 26 rue d’Ulm, 75005 Paris, France.
