Abstract
Cellular senescence, a cell-cycle arrest state upon stress or damage, can adversely impact aging and cancers. We have designed a novel near infrared fluorogenic nanoprobe, named D3, which can only be turned on by highly elevated levels of reactive oxygen species (ROS), critical players for the induction and maintenance of senescence, for real-time senescence sensing and imaging. In contrast to glowing senescent cells, non-senescent cells whose ROS levels are too low to activate the D3 signal remain optically silent. Upon systemic injection into senescent tumor-bearing mice, the D3 nanoprobe quickly accumulates in tumors, and its fluorescence signal is turned on specifically by senescence-associated ROS in the senescent tumors. The fluorescence signal at senescent tumors was 3-fold higher than that of non-senescent tumors. This groundbreaking design introduces a novel activation mechanism and a powerful imaging nanoprobe to identify and assess cellular senescence in living organisms.

Abstract
A novel donor-acceptor-donor (D-A-D) type compound containing pyrazine as the acceptor and triphenylamine as the donor has been designed and synthesized. The photophysical properties and biocompatibility of this probe, namely (OMeTPA)2-Pyr for live cell imaging were systematically investigated, with observed large Stokes shifts, high photostability, and low cytotoxicity. Furthermore, we demonstrated that (OMeTPA)2-Pyr could permeate live cell membranes for labeling. The proposed mechanism of this probe was the binding and shafting through membrane integral transport proteins by electrostatic and hydrophobic interactions. These salient and novel findings can facilitate the strategic design of new pyrazine-fused charge-neutral molecular platforms as fluorescent probes, for long-term in situ dynamic monitoring in live cells.

Abstract
Fluorescence imaging is one of the most widely used in vivo imaging methods for both fundamental research and clinical practice. Due to the reduced photon scattering, absorption, and autofluorescence in tissues, the emerging near-infrared (NIR) imaging (650-1700 nm) can afford deep tissue imaging with high spatiotemporal resolution and in vivo report the anatomical structures as well as the physiological activities in a whole-body level. Here, we give a brief introduction to fluorescence imaging in the first NIR (NIR-I, 650-950 nm) and second NIR (NIR-II, 1000-1700 nm) windows, summarize the recently developed NIR fluorophores and their applications in whole-body vascular system imaging, precision cancer theranostics, and regenerative medicine. Finally, the clinical applications and future prospects of in vivo NIR fluorescence imaging are also discussed.

Abstract
Identifying pro-inflammatory macrophages (M1) is of immense importance to diagnose, monitor, and treat various pathologies. In addition, adoptive cell therapies, where harvested cells are isolated, modified to express an M1-like phenotype, then re-implanted to the patient, are also becoming more prevalent to treat diseases such as cancer. In a step toward identifying, labeling, and monitoring macrophage phenotype for adoptive cell therapies, we developed a reactive oxygen species (ROS)-sensitive, gold nanoparticle (AuNP) that fluorescently labels M1 macrophages. AuNPs are electrostatically coated with a proteolysis resistant, fluorescein isothiocyanate-conjugated, poly-d-lysine (PDL-FITC) that is susceptible to backbone cleavage by ROS. When PDL-FITC is bound to AuNPs, fluorescence is quenched via a combination of nanoparticle surface (NSET) and Forster resonance (FRET) energy transfer mechanisms. Upon ROS-induced cleavage of PDL-FITC, up to a 7-fold change in fluorescence is demonstrated. PDL-FITC AuNPs were loaded into RAW 264.7 macrophages (RAWs) and primary bone marrow- derived macrophages (BMDMs) prior to in vitro polarization. For both cell types, detectable differences in intracellular fluorescence were observed between M1 polarized and non-stimulated (M0) control groups after 24 h using both confocal imaging and flow cytometry. PDL-FITC AuNPs can potentially be useful in identifying M1 macrophages within diverse cell populations and provide longitudinal macrophage response data to external cues.

Abstract
Light-based technique, including optical imaging and photoregulation, has become one of the most important tools for both fundamental research and clinical practice, such as cell signal sensing, cancer diagnosis, tissue engineering, drug delivery, visual regulation, neuromodulation, and disease treatment. In particular, low energy near-infrared (NIR, 700-1700 nm) light possesses lower phototoxicity and higher tissue penetration depth in living systems as compared with ultraviolet/visible light, making it a promising tool for in vivo applications. Currently, the NIR light-based imaging and photoregulation strategies have offered a possibility to real-time sense and/or modulate specific cellular events in deep tissues with subcellular accuracy. Herein, the recent progress with respect to NIR light for monitoring and modulating the spatiotemporal dynamics of cell functions in living systems are summarized. In particular, the applications of NIR light-based techniques in cancer theranostics, regenerative medicine, and neuroscience research are systematically introduced and discussed. In addition, the challenges and prospects for NIR light-based cell sensing and regulating techniques are comprehensively discussed.

Abstract
The silencing of an oncogene with a small interfering RNA (siRNA) is a promising way for cancer therapy. Its efficacy can be further enhanced by integrating with other therapeutics; however, transporting siRNA and other active ingredients to the same location at the same time is challenging. Here, we report a novel multifunctional nanodelivery platform by sequentially layering several functional ingredients, such as siRNAs, microRNAs, peptides, and targeting ligands, onto a core through charge-charge interaction. The prepared nanovectors effectively and programmably delivered multiple active components to maximize therapeutic combination with minimal off-targeting effects.

Abstract
The development of tumor targeted probes with strong signal and high contrast is always challenging in cancer imaging. Here, a unique multilayered activatable nanoprobe (MAN) is prepared to fulfill this long-standing goal. MAN adopts a versatile layer-by-layer fabrication technique that sequentially assembles multifunctional polyelectrolytes onto nanoparticles via charge-charge interaction. Unlike the common one-probe-one-fluorochrome construct, MAN offers a dramatic fluorescence enhancement by transporting a large quantity of quenched fluorochromes for maximal signal and contrast. Excellent signal amplification and retention with negligible cytotoxicity is observed in cell study. Upon systemic injection into mice, MAN quickly accumulates in tumor and its fluorescent signal is turned on by proteases overexpressed in tumors, resulting in >700% tumor-to-normal-tissue contrast. This multilayered fabrication provides a simple and powerful universal platform to design sensitive tumor imaging probes.

Abstract
Adult stem cell therapy has demonstrated improved outcomes for treating cardiovascular diseases in preclinical trials. The development of imaging tools may increase our understanding of the mechanisms of stem cell therapy, and a variety of imaging tools have been developed to image transplanted stem cells in vivo; however, they lack the ability to interrogate stem cell function longitudinally. Here, we report the use of a nanoparticle-based contrast agent that can track stem cell viability using photoacoustic imaging. The contrast agent consists of inert gold nanorods coated with IR775c, a reactive oxygen species (ROS) sensitive near-infrared dye. Upon cell death, stem cells produce ROS to degrade the cell. Using this feature of stem cells, the viability can be measured by comparing the IR775c signal to the ROS insensitive gold nanorod signal, which can also be used to track stem cell location. The nanoprobe was successfully loaded into mesenchymal stem cells (MSCs), and then, MSCs were transplanted into the lower limb of a mouse and imaged using combined ultrasound and photoacoustic imaging. MSC viability was assessed using the nanoprobe and displayed significant cell death within 24 h and an estimated 5% viability after 10 days. This nanoparticle system allows for longitudinal tracking of MSC viability in vivo with high spatial and temporal resolution which other imaging modalities currently cannot achieve.

Abstract
Triple-negative breast cancer (TNBC) patients exhibit the worst clinical outcome due to its aggressive clinical course, higher rate of recurrence, and a conspicuous lack of FDA-approved targeted therapies. Here, we show that multilayered nanoparticles (NPs) carrying the metastasis suppressor microRNA miR-708 (miR708-NP) localize to orthotopic primary TNBC, and efficiently deliver the miR-708 cargo to reduce lung metastasis. Using a SOX2/OCT4 promoter reporter, we identified a population of miR-708low cancer cells with tumor-initiating properties, enhanced metastatic potential, and marked sensitivity to miR-708 treatment. In vivo, miR708-NP directly targeted the SOX2/OCT4-mCherry+ miR-708low tumor cells to impair metastasis. Together, our preclinical findings provide a mechanism-based antimetastatic therapeutic approach for TNBC, with a marked potential to generate miR-708 replacement therapy for high-risk TNBC patients in the clinic. To our knowledge, this gold nanoparticle-based delivery of microRNA mimetic is the first oligonucleotide-based targeted therapy for TNBC.

Abstract
Stem cell-based regenerative medicine has attracted tremendous attention for its great potential to treat numerous incurable diseases. Tracking and understanding the fate and regenerative capabilities of transplanted stem cells is vital for improving the safety and therapeutic efficacy of stem cell-based therapy, therefore accelerating the clinical application of stem cells. Fluorescent nanoparticles (NPs) have been widely used for in vivo tracking of the transplanted stem cells. Among these fluorescent NPs, near-infrared (NIR) NPs have greatly improved the sensitivity, tissue penetration depth, spatial and temporal resolutions of the fluorescence imaging-based stem cell tracking technologies due to the reduced absorption, scattering, and autofluorescence of NIR fluorescence in tissues. Here, this review summarizes the recent studies regarding the tracking of transplanted stem cells using NIR NPs and emphasizes the recent advances of fluorescence imaging in the second NIR window (NIR-II, 1000-1700 nm). Furthermore, the challenges and future prospects of the NIR NP-based technologies are also discussed.

Abstract
Pluripotent stem cells can be isolated from embryos or derived by reprogramming. Pluripotency is stabilized by an interconnected network of pluripotency genes that cooperatively regulate gene expression. Here we describe the molecular principles of pluripotency gene function and highlight post-transcriptional controls, particularly those induced by RNA-binding proteins and alternative splicing, as an important regulatory layer of pluripotency. We also discuss heterogeneity in pluripotency regulation, alternative pluripotency states and future directions of pluripotent stem cell research.

Abstract
Recently, there has been much interest in the chirality-dependent cell affinity to enantiomorphous nanomaterials (NMs), since, at the nanoscale level, enantiomers of (bio)molecules have different effects on cell behaviors. In this respect, this study used enantiomorphous NMs with which to generate the Janus nanocomposite (NC) hydrogels as multifunctional biomaterials for studying chirality-dependent cell adhesion and cell migration. These Janus NC hydrogels possess two enantiomorphous NC hydrogels, in which the different halves of the hydrogel contain the opposite enantiomers of a biopolymer functionalized nanomaterials. Thus, the enantiomers contact each other only at the midline of the hydrogel but are otherwise separated, yet they are present in the same system. This advanced system allows us to simultaneously study the impact that each enantiomer of a biopolymer has on cell behavior under the same reaction conditions, at the same time, and using only a single biomaterial. Our results show that cells have higher affinity for and migrate toward the part of the Janus NC hydrogel containing the biopolymer enantiomer that the cells prefer.

Abstract
The unsatisfactory outcomes of typical multiple cytotoxic chemotherapeutic combination therapies used to treat patients have fostered a need for new unconventional combinations of therapeutic agents. Among the candidates, siRNA has been widely discussed and tested. However, the right time right place codelivery of siRNA with other types of active ingredients is challenging because of the possible differences among their physiochemical and pharmacodynamics properties. To accomplish a synergistic cytotoxic effect, a nanoassembly is thus designed to codeliver siRNA with other therapeutic agents. A siRNA, targeting prosurvival gene for the p75 neurotrophin receptor, and an organelle-fusing peptide, targeting mitochondria, are layered onto a nanotemplate by charge-charge interaction, followed by a layer of CD44 targeting ligand. The formulated triple-functional nanomedicine is efficiently internalized by the CD44 expressing triple-negative breast cancer cells. The encapsulated siRNA and the pro-apoptotic peptide are released inside cells, silencing the intended prosurvival gene, and inducing apoptosis by fusing the mitochondrial membrane, respectively. A synergistic effect is achieved by this three-agent combination. The design of the developed multifunctional nanomedicine can be generalized to deliver other siRNA and drugs for a maximum therapeutic combination with minimal off-targeting effects.

Abstract
There is a great demand to understand cell transplantation, migration, division, fusion, and lysis. Correspondingly, illuminant object-labeled bioprobes have been employed as long-term cellular tracers, which could provide valuable insights into detecting these biological processes. In this work, we designed and synthesized a fluorescent polymer, which was comprised of hydrophilic N-isopropylacrylamide polymers as matrix and a hydrophobic tetraphenylethene (TPE) unit as AIE-active cross-linkers (DDBV). It was found that when the feed molar ratio of N-isopropylacrylamides to cross-linkers was 22:1, the produced polymers demonstrated the desirable LCST at 37.5 °C. And also, the temperature sensitivity of polymers could induce phase transfer within a narrow window (32-38 °C). Meanwhile, phase transfer was able to lead the florescent response. And thus, we concluded that two responses occur when one stimulus is input. Therefore, the new cross-linker of DDBV rendered a new performance from PNIPAm and a new chance to create new materials. Moreover, the resulted polymers demonstrated very good biocompatibility with living A549 human lung adenocarcinoma cells and L929 mouse fibroblast cells, respectively. Both of these cells retained very active viabilities in the concentration range of 7.8-125 μL/mg of polymers. Notably, P[(NIPAm)22-(DDBV)1] (P6) could be readily internalized by living cells with a noninvasive manner. The cellular staining by the fluorescent polymer is so indelible that it enables cell tracing for at least 10 passages.

Abstract
Small interfering RNA (siRNA)-mediated gene silencing has shown prominent therapeutic effects in treating various diseases. However, adequate delivery and persistent gene silencing remain challenging. A nanoparticle-based delivery system which assembled by layering siRNAs between protease degradable polypeptides to show ultra-long gene silencing effect in vivo is developed. Gold nanoparticle is used as a scaffold for its unique properties including uniform size, biocompatibility, ready synthesis, and easy functionalization. A simple layer-by-layer fabrication approach, based on the electrostatic interaction between positively and negatively charged polymers, is applied to package the therapeutic siRNAs.

Abstract
One mechanism of photodynamic therapy (PDT) for the ablation of tumors is to induce apoptosis. Visualization of apoptosis during PDT in real-time is of great benefit for predicting and evaluating therapeutic outcomes. Herein, we engineered a highly stable and sensitive caspase-3 ferritin activatable probe (FABP/ZnPc) for simultaneous delivery of a photosensitizer (ZnPc) and real-time visualization of apoptosis during PDT. Upon near-infrared (NIR) light irradiation, ZnPc becomes active and initiates apoptosis, upon which the outer layer of the FABP/ZnPc is degraded by the apoptotic marker, caspase-3, to boost strong fluorescent signals, ultimately allowing real-time imaging of apoptosis. Our results demonstrate the utility of FABP/ZnPc as a tool for PDT and simultaneous imaging of caspase-3 activation in vitro and in vivo. Overall, the ability of FABP/ZnPc to image apoptosis during PDT will not only facilitate optimizing and personalizing the PDT strategy but is also important for understanding the mechanisms of PDT.
