AI Technical Summary

Technical Problem

Intravenously injected mesenchymal stromal cells (MSCs) are rapidly cleared in the body, leading to unstable efficacy. Furthermore, existing intravenous MSC injection protocols suffer from pulmonary retention and potential adverse reactions, limiting their clinical application.

Method used

Intravenous injection of spherical materials, such as mesenchymal stem cell (MSC) spheres or biomaterials of similar size, can reduce pulmonary retention, prolong the retention time in the blood and peripheral tissues, and carry drugs or bioactive molecules for treatment.

Benefits of technology

Intravenous injection of MSCs reduces pulmonary retention, improves efficacy, provides a safe route of administration, and can carry multiple molecules to produce synergistic effects, making it suitable for the diagnosis and treatment of a variety of diseases.

Abstract

本发明公开了球体物质在制备静脉注射剂中的应用,涉及生物医药技术领域。本发明将MSC细胞球或生物材料形成的球体物质的静脉注射作为一种新的体内递送方案。静脉注射MSC细胞球,相对于静脉注射离散的MSC而言,减少了MSC的肺部滞留,延长了MSC在血液和外周组织中的存留时间与活力,从而可望提高对自身免疫性疾病、炎性疾病和组织器官损伤的疗效。此外,生物材料球的静脉注射也是安全的,其能够携带药物、生物活性分子或检测分子,应用于动物疾病模型或患者的诊疗,比单体分子更有效、更持久,还可携带多种分子而产生协同效应。故此,本发明为细胞和生物材料在的临床应用提供了一种新的使用途径和研究方法。
