Manufacturing cell and gene therapies: challenges in clinical translation

Open access
Lee, Na Kyung, Chang, Jong Wook·2024·Annals of Laboratory Medicine

Abstract

The safety and efficacy of both cell and gene therapies have been demonstrated in numerous preclinical and clinical trials. Chimeric antigen receptor T (CAR-T) cell therapy, which leverages the technologies of both cell and gene therapies, has also shown great promise for treating various cancers. Advancements in pertinent fields have also highlighted challenges faced while manufacturing cell and gene therapy products. Potential problems and obstacles must be addressed to ease the clinical translation of individual therapies. Literature reviews of representative cell-based, gene-based, and cell-based gene therapies with regard to their general manufacturing processes, the challenges faced during manufacturing, and QC specifications are limited. We review the general manufacturing processes of cell and gene therapies, including those involving mesenchymal stem cells, viral vectors, and CAR-T cells. The complexities associated with the manufacturing processes and subsequent QC/validation processes may present challenges that could impede the clinical progression of the products. This article addresses these potential challenges. Further, we discuss the use of the manufacturing model and its impact on cell and gene therapy.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Transportation variables including extended transit time, temperature fluctuations, and improper thawing can compromise viability or biological activity of living cells and EV-based products.

    “Variables associated with transportation, including extended transit time, temperature fluctuations, and improper thawing procedures, can compromise the viability or biological activity of living cells and EV-based products (Lee and Chang, 2024; Gupta and Shaz, 2025).”

    From Isolator-based point-of-care manufacturing: a practical solution for GMP-compliant cell and extracellular vesicles therapy production (2025) · cites this paper as Lee and Chang, 2024

    The MSC-based cell therapies section lists freezing, storage, and shipment as steps in distributing cells, but does not say that transit time, temperature fluctuations, or improper thawing compromise viability. The AAV and LV-based gene therapies section discusses environmental effects on lentiviral-vector functionality during production, not transportation of living cells or EV-based products. Searches for the specified transportation and thawing effects found no passage addressing the claim. (LLM, conf=0.72)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
