Abstract

Mesenchymal stem/stromal cells (MSC) play a pivotal role in regenerative therapies. Recent studies show that factors secreted by MSC can replicate their biological activity, driving the emergence of cell-free therapy, likely to surpass stem cell therapy. Patents are an objective measure of R&D and innovation activities, and patent mapping allows us to verify the state of the art and technology, anticipate trends, and identify emerging lines of research. This review performed a search on Derwent World Patents Index™ and retrieved 269 patent families related to the MSC-derived cell-free products. Analysis reveals an exponential increase in patents from the mid-2010s, primarily focusing on exosomes. The patent's contents offer a great diversity of applications and associated technologies by using the products as medicinal agents or drug delivery systems. Nevertheless, numerous application branches remain unexplored, suggesting vast potential for cell-free technologies alone or combined with other approaches.

间充质干细胞衍生的无细胞技术：专利概况。

间充质干细胞/基质细胞（MSC）在再生疗法中发挥着举足轻重的作用。最近的研究表明，间充质干细胞分泌的因子可以复制其生物活性，从而推动了无细胞疗法的出现，并有可能超越干细胞疗法。专利是研发和创新活动的客观衡量标准，专利图谱使我们能够验证技术和工艺的现状，预测趋势，并确定新兴的研究方向。本综述在 Derwent World Patents Index™ 上进行了检索，共检索到 269 个与无间充质干细胞衍生产品相关的专利族。分析表明，从2010年代中期开始，专利数量呈指数级增长，主要集中在外泌体方面。这些专利的内容通过将产品用作药剂或给药系统，提供了多种多样的应用和相关技术。尽管如此，仍有许多应用领域尚未开发，这表明无细胞技术单独或与其他方法相结合具有巨大潜力。

期刊介绍： Biotechnology Letters is the world’s leading rapid-publication primary journal dedicated to biotechnology as a whole – that is to topics relating to actual or potential applications of biological reactions affected by microbial, plant or animal cells and biocatalysts derived from them. All relevant aspects of molecular biology, genetics and cell biochemistry, of process and reactor design, of pre- and post-treatment steps, and of manufacturing or service operations are therefore included. Contributions from industrial and academic laboratories are equally welcome. We also welcome contributions covering biotechnological aspects of regenerative medicine and biomaterials and also cancer biotechnology. Criteria for the acceptance of papers relate to our aim of publishing useful and informative results that will be of value to other workers in related fields. The emphasis is very much on novelty and immediacy in order to justify rapid publication of authors’ results. It should be noted, however, that we do not normally publish papers (but this is not absolute) that deal with unidentified consortia of microorganisms (e.g. as in activated sludge) as these results may not be easily reproducible in other laboratories. Papers describing the isolation and identification of microorganisms are not regarded as appropriate but such information can be appended as supporting information to a paper. Papers dealing with simple process development are usually considered to lack sufficient novelty or interest to warrant publication.
