受控给药系统,包括顺序和/或持续给药,已经被用来通过以依赖于时间和可重复的方式有效地给药来提高许多当前药物的治疗效果。在这项研究中,借助3D打印技术,制造了一种新型药物递送装置并进行了测试,以评估顺序递送功能。以海藻酸盐壳和聚乳酸-乙醇酸(PLGA)为核心,制备的管子显示出不同的荧光染料的顺序释放,并且与人胚胎肾(HEK293)细胞系或骨髓基质干细胞(BMSC)孵育时没有细胞毒性。通过这种递送系统控制药物或蛋白质的差异释放,有可能在从治疗癌症到再生医学的各种生物医学应用中得到应用。
Controlled drug delivery systems, that include sequential and/or sustained drug delivery, have been utilized to enhance the therapeutic effects of many current drugs by effectively delivering drugs in a time-dependent and repeatable manner. In this study, with the aid of 3D printing technology, a novel drug delivery device was fabricated and tested to evaluate sequential delivery functionality. With an alginate shell and a poly(lactic-co-glycolic acid) (PLGA) core, the fabricated tubes displayed sequential release of distinct fluorescent dyes and showed no cytotoxicity when incubated with the human embryonic kidney (HEK293) cell line or bone marrow stromal stem cells (BMSC). The controlled differential release of drugs or proteins through such a delivery system has the potential to be used in a wide variety of biomedical applications from treating cancer to regenerative medicine.
