Advances in biomaterial synthesis and fabrication, stem cell biology, bioimaging, microsurgery procedures, and microscale technologies have made minimally invasive therapeutics a viable tool in regenerative medicine. Therapeutics, herein defined as cells, biomaterials, biomolecules, and their combinations, can be delivered in a minimally invasive way to regenerate different tissues in the body, such as bone, cartilage, pancreas, cardiac, skeletal muscle, liver, skin, and neural tissues. Sophisticated methods of tracking, sensing, and stimulation of therapeutics in vivo using nano-biomaterials and soft bioelectronic devices provide great opportunities to further develop minimally invasive and regenerative therapeutics (MIRET). In general, minimally invasive delivery methods offer high yield with low risk of complications and reduced costs compared to conventional delivery methods. Here, minimally invasive approaches for delivering regenerative therapeutics into the body are reviewed. The use of MIRET to treat different tissues and organs is described. Although some clinical trials have been performed using MIRET, it is hoped that such therapeutics find wider applications to treat patients. Finally, some future perspective and challenges for this emerging field are highlighted.
生物材料合成和制造、干细胞生物学、生物成像、微创手术程序和微尺度技术的进步使微创治疗成为再生医学中一种可行的工具。治疗方法,本文定义为细胞、生物材料、生物分子及其组合,可以以微创的方式递送到体内不同的组织,如骨骼、软骨、胰腺、心脏、骨骼肌、肝脏、皮肤和神经组织。使用纳米生物材料和软生物电子设备对治疗方法进行体内跟踪、感应和刺激的复杂方法为进一步发展微创和再生治疗方法(MIRET)提供了巨大的机会。一般来说,与传统的输送方法相比,微创输送方法具有高产量、低并发症风险和低成本的优点。本文综述了将再生治疗方法递送到体内的微创方法。描述了 MIRET 用于治疗不同组织和器官的情况。尽管已经进行了一些临床试验,但希望这些治疗方法能够得到更广泛的应用,以治疗患者。最后,强调了这一新兴领域的一些未来展望和挑战。
