Shen et al (Nature Methods, 2017) explore and identify synthetic interactions among 73 cancer-associated genes. To perform their loss of function screen they combined CAS9-expressing cell lines with a sgRNA library of high titer lentiviral particles. Most of these gene interactions were subsequently validated by drug treatment. [Read more…]
Since the discovery of reprogramming factors in 2006 and the boom of CRISPR gene editing strategies, induced pluripotent stem cells (iPSC) have emerged as new cellular models. The development of 3D cell culture technologies has also contributed to the generation of induced Pluripotent Stem Cell (iPSC) derived cells, with unique applications from patient-specific drug responses testing, to regenerative medicine. I would like to introduce in this post a selection of reagents in this domain, a combination of both routine and innovative quality reagents, that I consider as bringing something extra to your stem cell research projects.
Today, I’d like to invite you to take a look at a highly efficient and useful kit, which brings together all the required components you need in a complete system for culturing and transfecting human pluripotent stem cells for gene editing.
The PluriQ™ G9™ Gene Editing System includes the G9™ Maintenance Medium and G9™ VTN Recombinant (vitronectin) plate coating for culturing human induced pluripotent (iPS) or embryonic stem (hES) cells in a manner that maximizes transfection by the included EditPro™ Stem Transfection Reagent to transfect genome editing constructs.

CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats)-Cas (CRISPR-associated) and Transcription Activator-Like Effector Nuclease (TALEN) are endonuclease based technologies aimed at developing targeted genome editing technologies.
CRISPR and TALEN provide Scientists with unique discovery tools for pathophysiology or genotype-phenotype studies by creating cellular models with gene knock-out, knock-in or tagging, promoter swapping, nucleotide substitution, protein truncation, reading frame disruption, modification of regulation by miRNA, genetic defect corrections…But, which one is the best for your application?
