Toward the development of a global induced pluripotent stem cell library

Area of Science:

• Immunology
• Regenerative Medicine
• Biotechnology

Background:

• Induced pluripotent stem cells (iPSC) offer potential for cell therapy due to their differentiation capacity.
• Immune compatibility remains a significant challenge for widespread iPSC-based cell therapies.
• Preselecting donor genotypes can mitigate immune rejection risks.

Purpose of the Study:

• To propose an international assessment for managing immune incompatibility in cell therapy.
• To outline strategies for operating a network of Good Manufacturing Practice (GMP) human leukocyte antigen (HLA) homozygous haplobanks.

Main Methods:

• Literature review and expert consultation on immune matching strategies.
• Analysis of logistical and regulatory requirements for GMP haplobank operation.
• Framework development for international collaboration.

Main Results:

• Identification of key challenges in managing immune incompatibility.
• Proposed operational models for GMP HLA homozygous haplobanks.
• Recommendations for international policy and standards.

Conclusions:

• Strategic preselection of iPSC donor genotypes is crucial for immune matching.
• Establishing a global network of GMP HLA homozygous haplobanks is feasible and necessary.
• International collaboration is essential for advancing cell therapy through immune compatibility management.
