Human Induced Pluripotent Stem Cells (HiPSC) Top: HiPSC express pluriotency markers OCT4, Nanog, LIN28 and SSEA-4. Bottom: HiPSC differentiate into cell derivatives from the 3 embryonic layers: Neuronal marker beta III tubulin (TUJ1), Smooth Muscle Actin (SMA) and Hepatocyte Nuclear Factor 3 Beta (HNF3b).

Cell Applications, Inc. has a deep, rich history in HiPSC

Human Dermal Fibroblasts (HDF) from Cell Applications were used by Nobel Laureate S. Yamanaka to establish iPSC in his groundbreaking publications in 2007, unleashing a revolution in stem cell biology. Yamanaka and collaborators demonstrated that expression of four transcription factors widely prevalent in embryonic stem cells is sufficient to trigger the transition of somatic cells towards a pluripotent state that resembles embryonic stem cells in many aspects, such as the expression of classic pluripotency markers and the ability to generate cell derivatives from the three embryonic germ layers.

HiPSC are generated from somatic cells, eliminating ethical considerations associated with scientific work based on embryonic stem cells. Furthermore, being donor/patient-specific, they open possibilities for a wide variety of studies in biomedical research. Donor somatic cells carry the genetic makeup of the diseased patient, hence HiPSC can be used directly to model disease on a dish.

Thus, one of the main uses of HiPSC has been in genetic disease modeling in organs and tissues, such as the brain (Alzheimers, Autism Spectrum Disorders), heart (Familial Hypertrophic, Dilated, and Arrhythmogenic Right Ventricular Cardiomyopathies), and skeletal muscle (Amyotrophic Lateral Sclerosis, Spinal Muscle Atrophy). The combination of HiPSC technology and gene editing strategies such as the CRISPR/Cas9 system creates a powerful platform in which disease-causing mutations can be created on demand and sets of isogenic cell lines (with and without mutations) serve as convenient tools for disease modeling studies.

Other applications of HiPSC and iPSC-differentiated cells include drug screening, development, efficacy and toxicity assessment. As an example, through the FDA-backed CiPA (Comprehensive in vitro Pro-Arrhythmia Assessment) initiative, HiPSC-derived cardiac muscle cells (cardiomyocytes) are poised to constitute a new standard model for the evaluation of cardiotoxicity of new drugs, which is the main reason of drug withdrawal from the market. Finally, HiPSC-differentiated cells are being used in early stage technology development for applications in regenerative medicine. Bio-printing and tissue constructs have also been considered as attractive applications for HiPSC.

StemoniX

Our partner StemoniX is a cutting-edge biotechnology company that is leading the development and manufacturing of HiPSC. They generate biologically accurate miniaturized organ microtissue for academic and industrial pharmaceutical research and discovery. StemoniX, a licensee of Academia Japans iPS patent portfolio, provides high quality HiPSC cells to researchers around the world. StemoniX HiPSC are thoroughly characterized for pluripotency with established pluripotency markers. Proven technology incorporating the latest innovations is able to provide cardiomyocytes with in vitro-like features. Confirmative tests show the HiPSC differentiate into derivatives from the 3 embryonic layers.
