Applied StemCell Demonstrates Efficient Knock-In of a 50 kb DNA Construct into Human iPSCs Using TARGATT™ Technology
MILPITAS, Calif., Nov. 11, 2025 – Applied StemCell, Inc. (ASC), today announced the successful knock-in of a 50 kilobase (kb) multifunctional DNA insert into human induced pluripotent stem cells (iPSCs) using its proprietary TARGATT™ technology. The achievement establishes a new benchmark for the size and complexity of genetic payloads that can be efficiently and site-specifically integrated into the human genome. [Read more…]
Bridging the Gap: Streamlining iPSC-Derived Cell Line Development from Donor Cells to MCB
Allogeneic iPSC-derived therapies hold immense promise, offering scalable, off-the-shelf solutions for a wide spectrum of diseases. However, the journey from donor cells to a gene edited, clinically compliant GMP Master Cell Bank (MCB) is fraught with challenges and is particularly vulnerable to risks stemming from misaligned early development.
A major bottleneck seen in the majority of iPSC therapeutic programs arises when development teams continue to rely on R&D grade cell lines to confirm proof-of-concept, conduct preclinical animal studies, and to start process & analytical development. [Read more…]

Allen Institute for Cell Science Releases Gene Edited Human Stem Cell Lines
First 5 cell lines in Allen Cell Collection empower the cell science community to explore the dynamic organization of the cell and to better understand health and disease
November 30, 2016 — The Allen Institute for Cell Science has released the Allen Cell Collection: the first publicly available collection of gene edited, fluorescently tagged human induced pluripotent stem cells that target key cellular structures with unprecedented clarity. Distributed through the Coriell Institute for Medical Research, these powerful tools are a crucial first step toward visualizing the dynamic organization of cells to better understand what makes human cells healthy and what goes wrong in disease.
“Each of our cells—the fundamental units of life—are like a city, with people and resources that move around and factories that generate those resources and carry out important functions,” says Rick Horwitz, Ph.D., Executive Director of the Allen Institute for Cell Science. “With these cell lines, we aim to give the cell science community a kind of live traffic map to see when and where the parts of the cell are with the clarity and consistency they need to make progress toward understanding human health and tackling disease.
