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 Hycells ® 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.
Hycells 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 acting of their own free will, with the donor’s rights and dignity serving as 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
Hycells provides a comprehensive, transparent, and auditable compliance documentation chain—covering donor screening, collection records, and a complete set of quality inspection reports—thereby providing robust support for 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. Hycells 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.

Compliance‑driven traceability establishes a clear “identity” for the product, but the real test lies in safety. While a multi‑donor pooling strategy ensures batch‑to‑batch consistency, it also inevitably elevates the risk of pathogen introduction. In the face of these associated risks and challenges, Heyousheng has never compromised on its manufacturing standards—relying on more precise design to deliver on its promise of enhanced safety.
This article will examine how He Yousheng proactively integrates the quality management system into the hospital setting, translating compliance requirements into concrete, actionable practices starting at the sample collection stage, thereby establishing a trust‑based chain that can withstand audit scrutiny.
In selecting hPL raw materials, Heyousheng consistently upholds the principle that “safety is determined at the source.” The samples used in production are rigorously collected in accordance with applicable standards and undergo stringent donor screening, effectively mitigating the risk of disease transmission at the very outset. Moreover, from informed consent forms and ethical approvals to clinical‑grade collection under the GCP framework, Heyousheng has established a fully traceable documentation chain, ensuring that every sample is accounted for and verifiable. In contrast to the industry’s longstanding reliance on the conventional model of using expired blood supplies from blood banks, this approach represents a structural, generational upgrade.
Recently, the research team led by Researcher Bian Yingjie at the Guangzhou National Laboratory, in collaboration with partners from Sun Yat-sen University, published a study titled “Iron overload in the tumor microenvironment induces CD8⁺ T cell ferroptosis and dysfunction” in the internationally renowned academic journal Nature Communications.
