Supply Chain, Manufacturing Capacity, and Scalability Challenges

The mammalian cell line bioprocessing sector in 2025 is navigating a complex landscape of supply chain, manufacturing capacity, and scalability challenges, shaped by both post-pandemic demand surges and ongoing innovation in biologics. The global demand for monoclonal antibodies, cell and gene therapies, and recombinant proteins continues to outpace the available manufacturing capacity, particularly for advanced therapies requiring high-containment or single-use systems. This has led to significant investments and strategic partnerships among leading contract development and manufacturing organizations (CDMOs) and biopharmaceutical companies.

Key industry players such as Lonza, Sartorius, Cytiva, and Thermo Fisher Scientific have announced major expansions of their mammalian cell culture manufacturing facilities. For example, Lonza is increasing its global footprint with new large-scale bioproduction sites in the US and Europe, aiming to address bottlenecks in clinical and commercial supply. Sartorius and Cytiva are investing in both equipment manufacturing and consumables, such as single-use bioreactors and filtration systems, to support flexible and rapid scale-up for clients.

Despite these expansions, the sector faces persistent supply chain vulnerabilities. The COVID-19 pandemic exposed dependencies on critical raw materials, such as resins, media, and single-use plastics, many of which are sourced from a limited number of suppliers. In 2025, companies are increasingly pursuing dual-sourcing strategies and regionalizing supply chains to mitigate risks. Thermo Fisher Scientific and Sartorius have both highlighted efforts to localize production and build redundancy into their supply networks.

Scalability remains a technical and operational challenge, especially for novel modalities like cell and gene therapies, which often require bespoke manufacturing processes and smaller batch sizes. The adoption of digital bioprocessing, automation, and process analytical technologies (PAT) is accelerating, with companies like Cytiva and Sartorius offering integrated solutions to improve process control and throughput.

Looking ahead, the outlook for 2025 and beyond suggests continued pressure on capacity, particularly for late-stage and commercial-scale production. Industry consortia and regulatory agencies are encouraging standardization and modular facility design to enable faster response to demand spikes. However, the sector’s ability to keep pace with innovation in biologics will depend on sustained investment in infrastructure, workforce development, and supply chain resilience.

Sustainability and Green Bioprocessing Initiatives

Sustainability and green bioprocessing are rapidly becoming central themes in mammalian cell line bioprocessing as the biopharmaceutical industry faces increasing pressure to reduce its environmental footprint. In 2025, leading manufacturers and technology providers are accelerating the adoption of eco-friendly practices, with a focus on energy efficiency, waste minimization, and the use of renewable materials.

A major trend is the shift from traditional stainless-steel bioreactors to single-use (disposable) technologies. Single-use systems, offered by companies such as Sartorius and Cytiva, reduce water and energy consumption by eliminating the need for cleaning and sterilization between batches. These systems also minimize cross-contamination risks and support flexible, modular facility designs, which can further lower resource use. However, the increased use of plastics in disposables has prompted industry-wide initiatives to improve recyclability and develop biodegradable alternatives.

To address the environmental impact of single-use plastics, suppliers like Merck KGaA (operating as MilliporeSigma in the US and Canada) are investing in take-back and recycling programs for used bioprocessing materials. These programs aim to divert significant volumes of plastic waste from landfills and incineration, supporting circular economy principles. Additionally, Thermo Fisher Scientific has announced sustainability targets that include reducing greenhouse gas emissions and increasing the use of renewable energy across its manufacturing sites.

Process intensification is another key strategy for sustainability. By increasing cell densities and product titers, companies can achieve higher yields with smaller facility footprints and reduced resource inputs. Lonza and FUJIFILM are among the contract development and manufacturing organizations (CDMOs) implementing intensified fed-batch and perfusion processes, which can cut water, energy, and raw material usage per gram of product.

Looking ahead, the industry is expected to further integrate digital tools and automation to optimize resource use and monitor environmental performance in real time. The adoption of green chemistry principles in media formulation and buffer preparation is also anticipated to grow, with suppliers like GE HealthCare (formerly part of Cytiva) exploring plant-based and animal-free raw materials.

Overall, the outlook for 2025 and beyond is one of continued innovation, with sustainability embedded as a core driver in mammalian cell line bioprocessing. Industry leaders are collaborating across the value chain to set new standards for green manufacturing, aiming to balance productivity with environmental stewardship.

Future Outlook: Disruptive Trends and Investment Opportunities

One of the most prominent trends is the adoption of intensified and continuous bioprocessing. Traditional batch processes are being replaced or supplemented by continuous manufacturing platforms, which offer improved productivity, reduced footprint, and enhanced product quality. Leading bioprocessing technology providers such as Sartorius and Merck KGaA are investing heavily in modular, automated systems that enable real-time monitoring and control, supporting the shift toward more flexible manufacturing paradigms.

Another key area of innovation is the development of advanced cell lines with higher productivity and robustness. Companies like Lonza and Cytiva are expanding their portfolios of proprietary mammalian cell lines, such as CHO (Chinese Hamster Ovary) and HEK293, engineered for optimized protein expression and scalability. These advancements are critical for meeting the growing demand for monoclonal antibodies, biosimilars, and novel therapeutic proteins.

Digitalization and data analytics are also reshaping the sector. The integration of artificial intelligence (AI), machine learning, and advanced process analytical technologies (PAT) is enabling predictive modeling, process optimization, and real-time quality assurance. Major players including Thermo Fisher Scientific are developing digital bioprocessing platforms that facilitate end-to-end data integration, supporting regulatory compliance and accelerating time-to-market for new therapies.

Investment opportunities are particularly strong in the areas of single-use technologies, automation, and cell and gene therapy manufacturing. The rapid expansion of single-use bioreactors and disposable process components, championed by companies like Pall Corporation, is reducing capital expenditure and increasing operational flexibility for both established biomanufacturers and emerging biotech firms.

Looking ahead, the convergence of these trends is expected to drive further consolidation and strategic partnerships across the bioprocessing ecosystem.
