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(MSC)在再生疗法中发挥着关键作用。最近的研究表明,MSC 分泌的因子可以复制其生物活性,推动无细胞治疗的出现,可能超越干细胞治疗。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的现状和水平,预测趋势,并识别新兴的研究方向。本综述在德温特世界专利索引™中进行了检索,检索到了 269 个与 MSC 衍生的无细胞产品相关的专利家族。分析显示,从中期 2010 年代开始,专利数量呈指数级增长,主要集中在细胞外囊泡上。专利的内容提供了广泛的应用和相关技术,将产品用作药物制剂或药物输送系统。然而,许多应用分支尚未得到探索,这表明无细胞技术本身或与其他方法结合具有巨大的潜力。
