Synthetic polymer coatings for long-term growth of human embryonic stem cells pp581 - 583

Luis G Villa-Diaz, Himabindu Nandivada, Jun Ding, Naiara C Nogueira-de-Souza, Paul H Krebsbach, K Sue O'Shea, Joerg Lahann & Gary D Smith

doi:10.1038/nbt.1631

The development of fully defined culture conditions for human embryonic stem cells (hESCs) should enhance experimental reproducibility, reduce unwanted contaminants and facilitate scale-up production. Villa-Diaz et al. show that a substrate made of the synthetic polymer PMEDSAH supports long-term culture of hESCs.

doi:10.1038/nbt.1640

Genetically engineered mouse models of cancer simulate the spontaneous development of tumors in their native tissue environment. Singh et al. establish their ability to predict the efficacy of different treatment regimens by comparing clinical trial results to equivalent experiments in mutated KRAS-driven mouse models of pancreatic and lung cancer.

Single-molecule enzyme-linked immunosorbent assay detects serum proteins at subfemtomolar concentrations pp595 - 599

David M Rissin, Cheuk W Kan, Todd G Campbell, Stuart C Howes, David R Fournier, Linan Song, Tomasz Piech, Purvish P Patel, Lei Chang, Andrew J Rivnak, Evan P Ferrell, Jeffrey D Randall, Gail K Provuncher, David R Walt & David C Duffy

doi:10.1038/nbt.1641

Rissin et al. increase the sensitivity of sandwich ELISA by segregating beads bearing a single enzyme-labeled immunoconjugate into femtoliter-volume reaction chambers. As the small volume of each well permits detection of extremely low levels of fluorescence, protein abundance is determined by counting the number of fluorescent wells as a percentage of the number of wells containing beads.


Identification of influenza A nucleoprotein as an antiviral target pp600 - 605

Richard Y Kao, Dan Yang, Lai-Shan Lau, Wayne H W Tsui, Lihong Hu, Jun Dai, Mei-Po Chan, Che-Man Chan, Pui Wang, Bo-Jian Zheng, Jian Sun, Jian-Dong Huang, Jason Madar, Guanhua Chen, Honglin Chen, Yi Guan & Kwok-Yung Yuen

doi:10.1038/nbt.1638

The spread of influenza virus strains resistant to the current generation of anti-viral drugs makes the identification of new druggable targets and lead compounds of prime importance. Kao et al. show that the influenza A nucleoprotein can be targeted by a small molecule that protects mice from lethal viral challenges.


Synthetic peptide-acrylate surfaces for long-term self-renewal and cardiomyocyte differentiation of human embryonic stem cells pp606 - 610

doi:10.1038/nbt.1629

The development of fully defined culture conditions for human embryonic stem cells (hESCs) should enhance experimental reproducibility, reduce unwanted contaminants and facilitate scale-up production. Melkoumian et al. show that a substrate made of peptides derived from extracellular matrix proteins supports long-term culture of hESCs and differentiation to cardiomyocytes.

The development of fully defined culture conditions for human embryonic stem cells (hESCs) should enhance experimental reproducibility, reduce unwanted contaminants and facilitate scale-up production. Rodin et al. show that a substrate made of human recombinant laminin-511 supports long-term culture of hESCs and human induced pluripotent stem cells.

Analysis of a genome-wide set of gene deletions in the fission yeast Schizosaccharomyces pombe pp617 - 623

Dong-Uk Kim, Jacqueline Hayles, Dongsup Kim, Valerie Wood, Han-Oh Park, Misun Won, Hyang-Sook Yoo, Trevor Duhig, Miyoung Nam, Georgia Palmer, Sangjo Han, Linda Jeffery, Seung-Tae Baek, Hyemi Lee, Young Sam Shim, Minho Lee, Lila Kim, Kyung-Sun Heo, Eun Joo Noh, Ah-Reum Lee, Young-Joo Jang, Kyung-Sook Chung, Shin-Jung Choi, Jo-Young Park, Youngwoo Park, Hwan Mook Kim, Song-Kyu Park, Hae-Joon Park, Eun-Jung Kang, Hyong Bai Kim, Hyun-Sam Kang, Hee-Moon Park, Kyunghoon Kim, Kiwon Song, Kyung Bin Song, Paul Nurse & Kwang-Lae Hoe

doi:10.1038/nbt.1628

Genome-wide single-gene deletion libraries can be important tools for understanding the molecular workings of an organism, but have only been created for a single eukaryotic species, Saccharomyces cerevisiae. Now, Kim et al. present a second collection of deletion mutants that covers 98.4% of the genes of Schizosaccharomyces pombe, allowing a systematic comparison of gene essentiality and knockout phenotypes between two eukaryotic species.
