Induced pluripotent stem cell (iPSC) based cell therapy CMC Services

Get in Touch

The number of studies focusing on induced pluripotent stem cell (iPSC)-based therapies has significantly increased in recent years, leading to a variety of pre-clinical and clinical studies in the treatment of conditions such as retinopathies, cardiovascular diseases, and neurodegenerative disorders. It is anticipated that Japan will soon grant market authorization for the first iPSC-based cell therapy designed to treat heart failure. As research on iPSCs progresses and knowledge in this field grows, various approaches are being employed to address critical chemistry, manufacturing, and controls (CMC) challenges, which include improving reprogramming efficiency, characterizing iPSCs and their derived cell products, and ensuring quality consistency, etc. Porton Advanced offers an integrated CMC service for iPSC-based cell therapies, supported by our extensive experience in stem cell and immune cell therapies.

We offer integrated CMC services ranging from reprogramming factor delivery vectors, reprogramming, to cell differentiation and large-scale manufacturing:

  • Episomal vectors, lentiviral vectors, and mRNA production for reprogramming
  • Cell reprogramming and iPSC colony selection
  • Gene modification/editing
  • GMP cell banking and cell storage
  • iPSC differentiation
  • iPSC-derived cell product GMP manufacturing
  • Process development and optimization
  • Analytical method development and optimization, analytical qualification, and validation
  • Testing Services for drug substance (DS) and drug Product (DP)
  • CMC information writing and regulatory submission

Reprogramming and Gene Editing Service

Porton Advanced is able to formulate “Yamanaka factor” based methodologies by implementing cell reprogramming techniques in Fibroblast cells or PBMC. To address immune rejection in transplantation treatment, assist with large-scale drug screening, and aid in the replacement of difficult-to-obtain primary cell lines, Porton Advanced is able to construct knock-out, knock-in, and point mutation cell lines via non-viral electroporation or lentiviral transduction. 

Using PBMC as starting cell

Case Study

The primary attempt of using episomal vectors to generate the iPSC cell line. We will optimize the process based on clients' projects.

To construct the iPSC cell line via gene editing/lentiviral transduction

Case Study

Porton Advanced is able to achieve gene editing efficiency at 90% after optimization

Cell Banking Service

Porton Advanced's scientists can manufacture GMP iPSC cell banks and cells that are compliant with NMPA, FDA, EMA, and PMDA regulatory standards and guidelines for your cell therapy projects. Our iPSC experts will provide the necessary quality and regulatory documents such as COAs, batch records, and quality technical agreements for your GMP iPSC MCB, PCM, or WCB. As of May 2025, Porton Advanced has delivered over 5 iPSC cell banking projects and dozens of other GMP cell banking projects.

Cell Differentiation and Manufacturing

The scientists from Porton Advanced have deep expertise and experience in tech transfer, cell differentiation, and GMP production. Using our GMP-compliant facility, we can accommodate iPSC-derived allogenic and autologous cell product production with over 1000 batches annually. As for filling systems, Porton Advanced provides manual, semi-automated, and automated processes to meet various cell type, container, and filling volume needs. 

Comprehensive analytical and testing strategies

To establish a reliable and reproducible manufacturing process from induced pluripotent stem cell (iPSC) generation to differentiation, it is crucial to identify the critical quality attributes (CQA) and critical process parameters (CPP). Porton Advanced has developed thorough testing and characterization methods for the starting materials, intermediate products, and final products.
