Abstract
Photoacoustic transfection consists in the use of photoacoustic waves, generated in the thermoelastic expansion of a confined material absorbing a short pulse of a laser, to produce temporary mechanical deformations of the cell membrane and facilitate the delivery of plasmid DNA into cells. We show that high stress gradients, produced when picosecond laser pulses with a fluence of 100 mJ/cm2 are absorbed by piezophotonic materials, enable transfection of a plasmid DNA encoding Green Fluorescent Protein (gWizGFP, 3.74 MDa) in COS-7 monkey fibroblast cells with an efficiency of 5% at 20 °C, in 10 minutes. We did not observe significant cytotoxicity under these conditions. Photoacoustic transfection is scalable, affordable, enables nuclear localization and the dosage is easily controlled by the laser parameters.

Abstract
A 3 mW focused femtosecond laser spot at a distance (>15 mum) has shown to attract the fillopodia from growth cones of primary neuronal cell cultures (mice E15). The phenomenological behavior of fillopodia is studied under short durations (~40 min) and different laser light conditions. The analysis of the fillopodia movement showed that they become significantly attracted towards the focused femtosecond laser light. In contrast, the use of continuous wave under the same conditions did not generate the same effect, the results of which were indistinguishable from when there was no laser light present (control condition). These results suggest the possible existence of an optically-induced signaling mechanism in growth cones.

Abstract
Mammalian cells exposed to electric field pulses of nanosecond duration (nsPEF; 60-ns, 12 kV/cm) experienced a profound and long-lasting increase in passive electrical conductance (G(m)) of the cell membrane, probably caused by opening of stable conductance pores (CPs). The CPs were permeable to Cl(-) and alkali metal cations, but not to larger molecules such as propidium iodide (PI). CPs gradually resealed; the process took minutes and could be observed even in dialyzed cells and in ATP- and glucose-free solutions. Cells subjected to long nsPEF trains (up to 200 pulses) underwent severe and immediate necrotic transformation (cell swelling, blebbing, cytoplasm granulation), but remained impermeable to PI for at least 30-60 min after the exposure. Both G(m) increase after short nsPEF trains and necrotic changes after long nsPEF trains were cell type-dependent: they were much weaker in HeLa than in GH3 cells. La(3+) and Gd(3+) ions significantly inhibited the nsPEF-induced G(m) increase (probably by blocking the CPs), and effectively protected intensely exposed cells from developing necrosis. We conclude that plasma membrane permeabilization is the principal cause of necrotic transformation in nsPEF-exposed cells and probably contributes to other known nsPEF bioeffects.

Abstract
Treatment to increase secretion of growth factors related to angiogenesis by gene transfection is a promising therapeutic solution for improving the outcome of tissue transplantation. We attempted to deliver a therapeutic vector construct carrying the human hepatocyte growth factor (hHGF) gene to skin grafts of rats using laser-induced stress waves (LISWs), with the objective of enhancing their adhesion. First we delivered the hHGF gene to rat native skin in vivo to determine the optimum gene transfer conditions. We then transferred the hHGF gene to excised rat skins, with which autografting was performed. We found that the density and uniformity of neovascularities were significantly enhanced in the grafted skins that were transfected using LISWs. These results suggest the efficacy of this method to improve the outcome of skin grafting. To our knowledge, this is the first experimental demonstration of a therapeutic efficacy based on LISW-mediated gene transfection. Since the present method can be applied not only to various types of tissues but also to bioengineered tissues, this technique has the potential to contribute to progress in transplantation medicine and future regenerative medicine.

Abstract
Topical delivery of antisense oligonucleotides (ASOs) and DNA is attractive for treatment of skin disorders. However, this delivery method is limited by the low permeability of the stratum corneum (SC). The objective of this study was to enhance and optimize the skin absorption of gene-based drugs by an erbium:yttrium-aluminum-garnet (Er:YAG) laser. The animal model utilized nude mice. In the in vitro permeation study, the Er:YAG laser treatment produced a 3-30-fold increase in ASO permeation which was dependent on the laser fluence and ASO molecular mass used. The fluorescence microscopic images showed a more-significant localization of a 15-mer ASO in the epidermis and hair follicles after laser application as compared with the control. The expressions of reporter genes coding for beta-galactosidase and green fluorescent protein (GFP) in skin were assessed by X-gal staining and confocal laser scanning microscopy. The SC ablation effect and photomechanical waves produced by the Er:YAG laser resulted in DNA expression being extensively distributed from the epidermis to the subcutis. The GFP expression in 1.4 J/cm2-treated skin was 160-fold higher than that in intact skin. This non-invasive, well-controlled technique of using an Er:YAG laser for gene therapy provides an efficient strategy to deliver ASOs and DNA via the skin.

Abstract
Plasmid DNA has been successfully delivered to mammalian cells by applying a nanosecond pulsed laser-induced stress wave (LISW). Cells exposed to a LISW were selectively transfected with plasmids coding for green fluorescent protein. It was also shown that transient, mild cellular heating (approximately 43 degrees C) was effective in improving the transfection efficiency.

Abstract
Pressure waves, which are generated by intense laser radiation, can permeabilize the stratum corneum (SC) as well as the cell membrane. These pressure waves are compression waves and thus exclude biological effects induced by cavitation. Their amplitude is in the hundreds of atmospheres (bar) while the duration is in the range of nanoseconds to a few microseconds. The pressure waves interact with cells and tissue in ways that are probably different from those of ultrasound. Furthermore, the interactions of the pressure waves with tissue are specific and depend on their characteristics, such as peak pressure, rise time and duration. A single pressure wave is sufficient to permeabilize the SC and allow the transport of macromolecules into the epidermis and dermis. In addition, drugs delivered into the epidermis can enter the vasculature and produce a systemic effect. For example, insulin delivered by pressure waves resulted in reducing the blood glucose level over many hours. The application of pressure waves does not cause any pain or discomfort and the barrier function of the SC always recovers.
