      Giant vesicles (GVs), which are closed lipid bilayer membranes with a diameter of more than 1 μm, have attracted attention not only as model cell membranes but also for the construction of artificial cells. For encapsulating water-soluble materials and/or water-dispersible particles or functionalizing membrane proteins and/or other synthesized amphiphiles, giant unilamellar vesicles (GUVs) have been applied in various fields, such as supramolecular chemistry, soft matter physics, life sciences, and bioengineering. In this review, we focus on a preparation technique for GUVs that encapsulate water-soluble materials and/or water-dispersible particles. It is based on the centrifugation of a water-in-oil emulsion layered on water and does not require special equipment other than a centrifuge, which makes it the first choice for laboratory use. Furthermore, we review recent studies on GUV-based artificial cells prepared using this technique and discuss their future applications.

    • [Original] Release of liposomally formulated infrared fluorescent probes included in giant cluster vesicles by ultrasound irradiation Peer-reviewed

      Detection of tumors and regional lymph nodes during surgery has been proposed in the diagnosis of lymphatic metastasis and the surgical treatment of malignant diseases. Giant cluster vesicles (GCVs), including liposomally formulated indocyanine green (LP-ICG) derivatives, are a possible candidate for agents to realize the two contradictory properties, i.e., retention in tissue for lesion-marking and trace for sentinel lymph nodes (SLNs) identification. We attempted to release the LP-ICG derivatives from GCVs using ultrasound contrast agents (UCAs) under ultrasound irradiation. An absorption spectrophotometer quantitatively evaluated the amounts of released LP-ICG derivatives. As a result, we demonstrated that it depended on conditions for sound pressure, burst length, and number density of UCAs, and had a sound pressure threshold independent of burst length and number density of UCAs. The results will aid to determine appropriate conditions to maximize the released amount of LP-ICG derivatives while keeping safety.

    • Stannous colloid mixed with indocyanine green as a tracer for sentinel lymph node navigation surgery Peer-reviewed

      Abstract

      The combined use of a vital dye and radioactive colloid reportedly performs better in detecting sentinel lymph nodes (SLNs) for cancers than the use of either of them alone. However, especially for gastric cancer, two endoscopic procedures are required to administer these two tracers, which burdens the patients and practitioners. Here we propose the use of stannous colloid (SnC) mixed with indocyanine green (ICG) as a new mixed tracer (SnC–ICG); its characteristics were investigated in vivo and in vitro to estimate its usefulness for SLN navigation. The tracers were administered to rats and the accumulation of radioactivity and/or near-infrared fluorescence were evaluated in the regional lymph nodes (LNs) using single positron emission computed tomography and near-infrared fluorescence imaging, respectively. SnC–ICG showed significantly better clearance from the injection site and better migration to primary LNs than the single administration of SnC or ICG aqueous solution. SnC–ICG demonstrated a wide particle size variability, stabilized to 1200-nm upon the addition of albumin in vitro; These properties could contribute to its behavior in vivo. The use of SnC–ICG could contribute better performance to detect SLNs for gastric cancer with less burden on both patients and medical practitioners.

    • Identifying and Manipulating Giant Vesicles: Review of Recent Approaches Invited Peer-reviewed

      Giant vesicles (GVs) are closed bilayer membranes that primarily comprise amphiphiles with diameters of more than 1 μm. Compared with regular vesicles (several tens of nanometers in size), GVs are of greater scientific interest as model cell membranes and protocells because of their structure and size, which are similar to those of biological systems. Biopolymers and nano-/microparticles can be encapsulated in GVs at high concentrations, and their application as artificial cell bodies has piqued interest. It is essential to develop methods for investigating and manipulating the properties of GVs toward engineering applications. In this review, we discuss current improvements in microscopy, micromanipulation, and microfabrication technologies for progress in GV identification and engineering tools. Combined with the advancement of GV preparation technologies, these technological advancements can aid the development of artificial cell systems such as alternative tissues and GV-based chemical signal processing systems.

      Lipid-coated microbubbles (MBs) with an indocyanine green (ICG) derivative were fabricated for ultrasound and near-infrared (NIR) fluorescence dual imaging. We characterized the NIR-fluorescence intensity, stability and viscoelastic properties of the encapsulating lipid shell, focusing on the influence of the ICG derivative and lipid compositions. In terms of the NIR fluorescence intensity, the fluorescence intensity of the MBs (with the ICG derivative) was significantly affected by the lipid composition of the MB shell. Regarding the contrast agent used for ultrasound imaging, the stability of the MBs and viscoelastic properties of shell also depended on the lipid compositions, while the incorporation of the ICG derivative into the MB shells had a negligible effect. The performance of this contrast agent for ultrasound and NIR fluorescence dual-imaging exhibited a significant trade-off relationship for the lipid composition.

      粒子径200、400、800nmの近赤外(NIR)蛍光リポソームを用いて、生体内分布を調べた。ラットモデルにおける組織学的分析から、リポソームの粒子径が増加するに従って、一次リンパ節における分布度が低下していた。粒子径400nmのリポソーム製剤はブタモデルにおいて、粒子は胃から一次リンパ節に留まっていた。この粒子径は先行研究でSLNの検出に使用されたトレーサーの最適サイズよりも大きかった。NIR蛍光画像でSLNを効率よく検出するには、リポソームの粒子径を調整することが重要であると考えられた。

      In this paper, we propose a technically simple method of destroying a tissue marker composed of giant cluster-like vesicles (GCVs) to facilitate laparoscopic surgeries; the method releases various biological tracers contained in GCVs. An ultrasonically activated device (USAD) emitting 55.5 kHz ultrasound was employed for this purpose. Optical microscopy and fluorospectrophotometry revealed the destruction of GCVs after ultrasound irradiation when the blade tip was set 1.0 mm or closer to, but not directly in contact with, a GCV-containing cell. This means that USAD could be safely used for destroying this GCV tissue marker in clinical settings. (C) 2016 The Japan Society of Applied Physics
