Abstract
The airway epithelium is the footstone to maintain the structure and functions of lung, in which resident basal cells (BCs) maintain homeostasis and functional regeneration of epithelial barrier in response to injury. In recent clinical researches, transplanting BCs has shown great inspiring achievements in therapy of various lung diseases. In this study, we report a noninvasive optical method to activate BCs for airway epithelium regeneration in vivo by fast scanning of focused femtosecond laser on BCs of airway epithelium to active Ca2+ signaling and subsequent ERK and Wnt pathways. The photoactivated BCs present high proliferative capacity and maintain high pluripotency, which enables them to plant in the injured airway epithelium and differentiate to club cells for regeneration of epithelium. This optical method can also work in situ to activate localized BCs in airway tissue. Therefore, our results provide a powerful technology for noninvasive BC activation in stem-cell therapy of lung diseases.

JOURNAL OF BIOPHOTONICS 2022; 15:e202200144.

Abstract
A variety of physical and chemical methods have been developed in research laboratories for the induction of stem cell differentiation. However, the use of exogenous chemicals and materials may limit their widespread utility in clinics. To develop a clean and precise induction approach with minimal invasion, we reported here that 1-second stimulation by a tightly focused femtosecond laser (fsL) (140 mW/μm2 , 200 fs) can modulate the signaling systems in human mesenchymal cells, such as intracellular calcium and reactive oxygen species. Upon stimulation on an automatic platform, hMSCs were found to express osteoblastic markers and form calcium-rich deposits. Moreover, tissue mineralization was observed when the fsL-illuminated hMSCs were ectopically transplanted into nude mice. Collectively, we described a novel and non-contact optical stimulation method for cell differentiation with high spatiotemporal resolution.

Abstract
Ultra-precise stimulation solely to individual mitochondria, without any influence to the whole cell, is quite difficult by traditional biochemical reagents. In mitophagy research, the mitochondria and even the whole cell usually suffer irreversible and great damage caused by treatment with potent chemicals. In this protocol, we present the technical procedures of our developed noninvasive ultra- precise laser stimulation (UPLaS) technology, which introduces precise stimulation to individual mitochondria, to excite mitochondrial Ca 2+ (mitoCa 2+ ) oscillations, with little perturbation to mitochondrial membrane potential (MMP), or mitochondrial reactive oxygen species (mitoROS). The mitoCa 2+ oscillation by UPLaS was able to initiate the PINK1/Parkin pathway for mitophagy. This protocol has good potential to benefit researches on mitophagy and mitochondrial diseases. Graphic abstract: Figure 1.Flowchart of the UPLaS technology.The femtosecond laser (1030 nm, 1 MHz, 220 fs) can stimulate individual mitochondria (1 μm 2 ) for a short period (0.1 s), whereas confocal microscopy (CM) provides continuous cell imaging to monitor molecular dynamics in real time, before and after UPLaS.

Abstract
Gene therapy has become an effective treatment modality for some conditions. Laser light may augment or enhance gene therapy through photomechanical, photothermal, and photochemical. This review examined the evidence base for laser therapy to enhance nucleic acid transfection in mammalian cells. An electronic search of MEDLINE, Scopus, EMBASE, Web of Science, and Google Scholar was performed, covering all available years. The preferred reporting items for systematic reviews and meta-analyses guideline for systematic reviews was used for designing the study and analyzing the results. In total, 49 studies of laser irradiation for nucleic acid delivery were included. Key approaches were optoporation, photomechanical gene transfection, and photochemical internalization. Optoporation is better suited to cells in culture, photomechanical and photochemical approaches appear well suited to in vivo use. Additional studies explored the impact of photothermal for enhancing gene transfection. Each approach has merits and limitations. Augmenting nucleic acid delivery using laser irradiation is a promising method for improving gene therapy. Laser protocols can be non-invasive because of the penetration of desirable wavelengths of light, but it depends on various parameters such as power density, treatment duration, irradiation mode, etc. The current protocols show low efficiency, and there is a need for further work to optimize irradiation parameters.

Abstract
On-cue regulation of gene transcription is an invaluable tool for the study of biological processes and the development and integration of next-generation therapeutics. Ideal reagents for the precise regulation of gene transcription should be nontoxic to the host system, highly tunable, and provide a high level of spatial and temporal control. Light, when coupled with protein or small molecule-linked photoresponsive elements, presents an attractive means of meeting the demands of an ideal system for regulating gene transcription. In this review, we cover recent developments in the burgeoning field of light-regulated gene transcription, covering both genetically encoded and small-molecule based strategies for optical regulation of transcription during the period 2012 till present.

Abstract
The microenvironment is an important factor of stem cells regulating their maintenance, survival, and differentiation. The glycation of proteins with reducing sugars through nonenzymatic reactions induces the collagen cross-linking, which causes tissue stiffening, which is enhanced during aging and diabetes. In this study, we aimed to analyze the effect of glycated collagen on the stem cell culture and differentiation. The collagen type 1 was modified by glycation with mannose, rhamnose, arabinose, and glucose. After the culture of mesenchymal stem cells on the coated surfaces with glycated collagen, the differences in cell adhesion, proliferation, and differentiation were compared. The results showed that the modifications did not induce apoptosis or cause cell death. However, the culture of cells on modified collagens improved the proliferation. It was found that the mannose-modified collagen stimulated the adipogenic differentiation of stem cells, and rhamnose-modified collagen supports the differentiation into both osteogenic and insulin-producing cells. The low concentration of monosaccharides during glycation process improved the characteristics of the matrix protein in favor of stem cell differentiation. Modification of the collagen by glycation might be used as a tool to improve natural polymers for material-induced stem cell differentiation in the future.

Abstract
Micro-/nanosphere-mediated femtosecond laser cell perforation is one of the high throughput technologies used for macro-molecule-delivery into multiple cells. We have demonstrated the delivery of plasmid-DNA/liposome complexes into cells using biodegradable polymer microspheres and a femtosecond laser and investigated the intracellular localization of the complexes by delivering fluorescence-labeled plasmid-DNA/liposome complexes into cells. The utilization of liposomes increases the number of complexes delivered into the cytoplasm by laser illumination, which contributed to the increased transfection rate. In the experiment involving polystyrene (PS) microspheres of different diameters, the fluorescence of the complexes was detected in the nucleus as well as cytoplasm after laser illumination for PS microspheres of 3.0 μm diameter. The direct delivery of complexes into the nucleus is probably attributed to the enhancement of the nuclear membrane permeability by the enhanced optical field obtained close to the nucleus. These revelations on the intracellular localization of foreign DNA would provide effective laser-based transfection.

Abstract
Optically controlled release of a DNA strand based on a nonradiative relaxation process of black hole quenchers (BHQs), which are a sort of dark quenchers, is presented. BHQs act as efficient energy sources because they relax completely via a nonradiative process, i.e., without fluorescent emission-based energy losses. A DNA strand is modified with BHQs and the release of its complementary strand is controlled by excitation of the BHQs. Experimental results showed that up to 50% of the target strands were released, and these strands were capable of inducing subsequent reactions. The controlled release was localized on a substrate within an area of no more than 5 micrometers in diameter.
