Non-integrative mRNA reprogramming has proven to be the most efficient and clinically-relevant method for human induced pluripotent stem cells (iPSCs) reprogramming. Armed with advanced platform and expertise, Creative Biolabs provides the most rapid integration-free method for iPSC reprogramming. Our pipeline is built to meet the customer’s project and assay-specific requirements for cellular characteristics and functionality. The scalability of our iPSCs ranges from one million to one billion cells and can be delivered on a predictable schedule.
The derivation of iPSCs sparked widespread enthusiasm for the development of new models of human disease, enhanced platforms for drug discovery and more widespread use of autologous cell-based therapy. The emergence of reprogramming technology enabled the use of disease-specific iPSCs in established directed-differentiation protocols. Improvements in reprogramming methodologies have increased the efficiency of iPSC derivation and the quality of iPSC lines in use. Noncorrected cells differentiated from patient-derived iPSCs have been used in drug screening. Currently, a handful of candidate drugs identified in iPSC-based systems are under study in human trials.
It has been shown that cells terminally differentiated from human iPSCs are susceptible to infection with human pathogens, opening a new frontier for probing host-pathogen interactions. Human iPSC-based systems overcome the limitation of species specificity of infectious pathogenicity and inflammatory responses.
iPSC-based systems have recently provided platforms to screen for novel antimicrobials.
Upon the development of patient-specific iPSCs, related techniques were applied to disease modeling to derive an affected cell lineage.
iPSC-based chimeric disease modeling by xenotransplantation has emerged as a reliable tool to fuel these advances by faithfully modeling human diseases such as glioblastoma, stroke, osteosarcoma, and Parkinson disease.
A ready source of iPSCs is critical to the effective study of differentiation pathways and the investigation of the therapeutic potential of iPSCs. Since the discovery that human iPSCs could be generated by inducing expression of specific reprogramming factors, many different reprogramming technologies have emerged to generate iPSCs. The evolution of reprogramming technologies has culminated in the development of synthetic mRNA-mediated reprogramming. In that way, engineered synthetic self-replicating mRNA is used to mimic cellular RNA to generate human iPSCs. The single RNA strand contains several reprogramming factors and enables extremely efficient reprogramming using a single transfection step without any viral intermediates or host genome integration.

For iPSCs creation, expression of reprogramming factors as mRNAs is available zero-footprint technology. The single RNA strand, containing the OCT-4, KLF-4, SOX-2 and GLIS1, enables extremely efficient reprogramming using a single transfection step without any viral intermediates or host genome integration. Once iPSCs are generated, the RNA can easily be selectively eliminated by removing the interferon-gamma inhibitor, B18R from the cell culture medium.
Ability to source tissue and generate iPSCs from a specific patient clinical profile.
Integration-free, non-viral, safe and efficient.
Readily available lineages offered at scale, coupled with flexible, efficient and iterative custom solutions.
Industry-leading scientific experts will help to develop a cost-effective and milestone driven project to meet your research needs.
Protocols include but are not limited to assessing cell count, viability, genomic stability, and expression of lineage markers at the transcriptome and protein levels.
Start-to-finish assistance and support throughout the entire process are provided by a dedicated technical team.
Our advanced generation technology can be used to transform samples from skin, blood and urine. The resultant iPSCs possess low transgene persistence, increased chromosomal stability and reduced clonal variation. As RNA reprogramming leads to decreased copy number variation, it also reduces the risk of oncogenesis and abnormal karyology. Creative Biolabs is dedicated to providing first-class iPSC reprogramming services for our customers. Our services will contribute greatly to the success of your iPSC programs.
