Cell and gene therapy is becoming one of the most promising areas of modern healthcare, offering new ways to treat cancer, genetic disorders, neurological conditions, and other serious diseases. The global sector was valued at approximately USD 8.94 billion in 2025 and is expected to reach USD 10.44 billion in 2026. By 2035, it could climb to around USD 47.18 billion, expanding at a CAGR of 18.1% between 2026 and 2035.
Cell therapy involves introducing healthy or modified cells into the body to repair damaged tissues or improve biological functions. Gene therapy, meanwhile, works by introducing, replacing, or modifying genetic material to address the underlying causes of disease. Together, these approaches are opening new possibilities for treatments that were previously difficult or impossible to achieve.
Oncology Remains a Major Focus
Cancer continues to be the leading therapeutic area for cell and gene therapy development. The oncology segment accounted for 39.48% of the sector in 2025, supported by rising cancer cases, advances in CAR-T therapies, gene editing, and increasing investment in innovative treatments.
Genetic disorders are another important area of growth. The segment represented 12.05% in 2025 and is expected to expand at the fastest rate during the forecast period. Technologies such as CRISPR are creating new possibilities for treating inherited conditions, including sickle cell disease, hemophilia, and muscular dystrophy.
Viral Vectors and Cell Therapy Lead
Cell therapy held the largest share at 64.78% in 2025, supported by growing clinical research, stem cell applications, and increasing numbers of clinical trials. Gene therapy accounted for 35.22% and is advancing rapidly as gene-editing technologies become more precise.
Viral vectors remained the leading delivery method, accounting for 72.20% in 2025. Their ability to efficiently deliver genetic material into cells makes them valuable for advanced therapeutic applications. At the same time, non-viral approaches such as lipid nanoparticles are gaining attention because of their flexibility, scalability, and potentially improved safety profiles.
Regional Growth and Investment
North America led globally with 49.88% in 2025, supported by advanced healthcare infrastructure, strong biotechnology research, extensive clinical trials, and supportive regulatory pathways.
Asia Pacific is expected to experience the fastest growth, with its value projected to increase from USD 1.78 billion in 2025 to USD 11.74 billion by 2035. China, India, and Japan are strengthening research, manufacturing, and clinical capabilities.
Investment is also accelerating. In March 2025, Bharat Biotech announced a $75 million investment in a cell and gene therapy facility in Telangana. Such investments can strengthen manufacturing capacity and support the development of more accessible advanced treatments.
With continued innovation in gene editing, personalized medicine, manufacturing, and clinical research, cell and gene therapy is moving closer to becoming a mainstream approach for treating complex diseases.
