About Us

Applied StemCell Inc. (ASC) is a fast growing biotechnology company headquartered in Milpitas, California.

The company was founded on May 8, 2008 with a goal to advance gene-editing and stem cell innovation for biomedical research and the biotechnology industry.

After more than 11 years' of research and development, ASC is proud to offer an optimized series of tools for basic research study, drug discovery, bio-processing, bio-production and preclinical applications.

We are currently focusing on three areas:

Cell line generation for bio-production and bioassays

Patient-relevant cell models for personalized medicine and

Physiologically predictive animal models of human diseases

We are striving to improve and expand our technologies and product lines to meet the increasing requirements of the biomedical community.

  • Establishing disease-specific isogenic models
  • Developing master cell lines for antibody/protein production
  • Generating iPSCs from patients containing the corrected mutations or inserted genes for pre-clinical applications
  • Generating animal models (mouse/rat models)

Using our TARGATT™ technology, a gene-of-interest can be specifically inserted at a well-characterized, transcriptionally active locus in the genome with guaranteed transgene expression.

This site-specific Knock-in technology has been first established in mouse models, and we have successfully applied it to human cell lines.

We are moving forward to various projects that will combine the CRISPR/Cas9 technology and TARGATT™ for highly specified transgene expression.

TARGATT™ Technology Applications:


ASC Therapeutics is a division of Applied StemCell, Inc. which focuses on the development of curative therapeutic products enabled by its various gene editing and stem cell technologies.

The company's therapeutics pipeline includes several preclinical stage projects focusing on blood disorders characterized by high genetic penetrance.

Advantages of Our Gene Editing Therapy:

  • Lifetime Effect: Therapeutic gene integrated into the genome instead of episomal
  • Safe: Site--specific gene integration
  • High Potency and efficact: New AAV capsids
  • Lower immunogenicity: Lower viral dose
  • Lower cost
