Microbubble-Enhanced Sonoporation: Efficient Gene Transduction Technique for Chick Embryos
| Procedures for sonoporation-mediated gene transduction. Procedures consist of two steps. | |
| a, b: | DNA-microbubble mixture was injected into chick limb bud at HH stages 20-21. |
| c, d: | Immediately after injection, ultrasound irradiation was performed with the ultrasound probe placed adjacent to the injected site (introduction into the chick forelimb bud is illustrated in d). |
| Time course of GFP expression after sonoporation. pEGFP was transduced into chick limb buds by utilizing sonoporation at HH stage 20-21. Brightfield photos of the transduced limbs are shown in a-d. a, e: Three hours after transduction, GFP expression was detectable in the limb bud mesenchyme. The level of GFP expression progressively increased (b, f), reaching a plateau after 12h of gene transduction (c, g). d, h: The level of GFP expression decreased after 24h of transduction. (Scale bar = 1mm.) |
| Histological analysis of transduced chick limb buds. | |
| a： | pEBActN-LacZ was introduced into limb buds (at HH stages 20-21) by utilizing sonoporation. LacZ expression was detected in anterior limb buds after 12h. The white line in a represents the position of a section in b. |
| b： | In the transverse section of a transduced limb bud, LacZ-positive cells were detected in the mesenchyme. Scale bar = a: 1mm, b: 50um |
| Additional digit formation as a result of ectopic cShh expression. c: Additional digits were observed upon transducing pCAGGScShh into anterior chick limb buds. a: pCAGGS-cShh and pEGFP were coexpressed to monitor gene transduction efficiency. GFP expression was detected in anterior limb buds. b: Normal wing formation 12h after sonoporation-mediated pEGFP transduction as a control. c: Digit 3 duplication with truncated digit 2 formation. The asterisk shows a small cartilaginous element as previously reported (Drossopoulou et al., 2000). Scale bar = 1mm. |
| Serial gene transduction into the developing limb. pEGFP was introduced first to the anterior limb mesenchyme. A second gene introduction into the posterior limb mesenchyme was performed immediately after the initial transduction. GFP expression was detected after 12h of the transduction at both sites. Scale bar = 1mm. |

Fig. 3. Ultrasonographic Images of PEG-Liposomes and Bubble Liposomes
To confirm the perfluoropropane gas within bubble liposome, they were imaged with an ultrasound imaging machine. Liposomes were injected into latex tube in water bath and imaged. Bubble Liposomes made ultrasound echo signal increased, but PEG-liposomes did not so. Therefore, it confirmed that bubble liposomes were including perfluoropropane gas. In addition, it is expected that bubble liposomes are able to be utilized as ultrasound imaging agents.

In vivo luciferase imaging at 2 days after transfection in the mouse treated with plasmid DNA, bubble liposomes and ultrasound exposure. The photon counts are indicated by the pseudo-color scales. To evaluate the ability of bubble liposomes to in vivo gene delivery, we attempted to deliver plasmid DNA with bubble liposomes into femoral artery. In this study, we also examined the gene delivery with conventional lipofection method (1). The gene expression with ultrasound or bubble liposomes was low level. In addition, the gene expression was very low even in using Lipofectamine 2000. However, in the combination of bubble liposomes and ultrasound exposure, gene expression was higher than other groups. And the gene expression was observed at only area of ultrasound exposure (2). |
