Cell culture additives It refers to chemically defined or animal-free additives used in cell culture as substitutes for traditional animal sera, such as fetal bovine serum, with the aim of reducing batch-to-batch variability, minimizing contamination risks, and enhancing experimental reproducibility. Its composition typically includes growth factors, carrier proteins, trace elements, and other components, making it suitable for applications in vaccine production, biopharmaceuticals, regenerative medicine, and other fields.
End-to-end compliance lays the foundation for the safety of cell therapy.
HiXpan, innovatively developed by He Yousheng ® Cell culture additives have been officially launched. As the first domestically developed product specifically tailored for drug registration applications and rigorously compliant with GMP manufacturing standards, we are committed to providing a safe and reliable source of supply for the cell therapy field.
He Yousheng has established a comprehensive, end-to-end quality control system that exceeds industry standards, ensuring that every stage—from raw materials to the final product—meets stringent regulatory requirements for drug registration.
1. Traceable origins; donor safety is paramount.
Rigorous donor screening: A comprehensive health assessment is conducted, encompassing medical history, travel history, and lifestyle factors, and all relevant infectious disease markers—including HBV, HCV, HIV, TPPA, HTLV, CMV, and EBV—are thoroughly tested in accordance with national regulations.
Full Informed Consent: Uphold the ethical baseline by ensuring that every donor signs a consent form only after being fully informed and volunteering their consent; the protection of donors’ rights and dignity is the foundation of all our work.
2. Standardization and Normalization of the Entire Process
Standardized Collection Center: All collection procedures comply with GCP standards and are performed in a standardized manner by experienced, qualified healthcare professionals, ensuring the safety and controllability of the entire process.
Single Blood-Collection-Point Assurance: Strictly adhere to a single, traceable blood-collection-point source to completely eliminate pooled sampling and minimize the risk of potential cross-contamination.
3. Rigorous craftsmanship, with quality fully controllable throughout the process.
Compliant manufacturing process: A rigorously validated process is employed to ensure efficient release of growth factors while achieving thorough viral inactivation and elimination of immunogenicity.
Comprehensive quality testing: Each batch of product undergoes multiple critical quality-control assays, including endotoxin testing, sterility testing, and assessment of growth-factor activity and concentration, to ensure outstanding batch-to-batch consistency and stability.
4. Comprehensive compliance documentation support
HeYouSheng provides a comprehensive, transparent, and auditable compliance documentation chain—covering donor screening, collection records, and a complete set of quality inspection reports—thereby robustly supporting clients in meeting the stringent regulatory reviews imposed by drug regulatory authorities. Support on-site customer audits.
Using starting materials from compliant sources is the cornerstone of ensuring the safety and efficacy of clinical therapies. Heyousheng is committed to partnering with you to advance the biopharmaceutical industry toward a more standardized, safe, and ethically sound future—through impeccable compliance and quality.

Group 1: Formula 1 + Hycells Cell Culture Supplement (Lot: 0528)
Group 2: Formula 2 + Competitor 1 cell culture supplement
Group 3: Formula 2 + Competitor 2 cell culture supplement
Group 4: Formula 2 + Hycells Cell Culture Supplement (Lot: 0318)
Group 5: Formula 2 + Hycells Cell Culture Supplement (Lot: 0528)
*Formula 1 and Formula 2 consist of the basal medium plus different combinations of activation factors, respectively.
Based on the amplification results, the Hycells cell culture supplement performs similarly to the Competitor 2 cell culture supplement and outperforms the Competitor 1 cell culture supplement. Moreover, different batches of the Hycells cell culture supplement exhibit comparable performance.
