Kartogenin (KGN), a small molecular compound, can induce bone marrow-derived mesenchymal stem cells (BMSCs) into chondrocytes. The previous in vitro study showed that kartogenin also had a chondrogenesis effect on synovium derived mesenchymal stem cells (SMSCs). Herein, we present the effect of an ultraviolet-reactive, rapidly cross-linkable scaffold integrated with kartogenin-loaded nanoparticles using an innovational one-step technology. In vivo studies showed its potential role for cell homing, especially for recruiting the host's endogenous cells, including BMSCs and SMSCs, without cell transplantation. Of note, the regenerated tissues were close to the natural hyaline cartilage based on the histological tests, specific markers analysis, and biomechanical tests. This innovative KGN release system makes the chondrogenesis efficient and persistent.}, number={1}, journal={ACS NANO}, author={Shi, Dongquan and Xu, Xingquan and Ye, Yanqi and Song, Kai and Cheng, Yixiang and Di, Jin and Hu, Quanyin and Li, Jianxin and Ju, Huangxian and Jiang, Qing and et al.}, year={2016}, month={Jan}, pages={1292–1299} }

We here report the development of the LGFU as a stimulus for promoted drug release from microgels integrated with drug-loaded polymeric nanoparticles. The pulsed waves of ultrasound, generated by a carbon black/polydimethylsiloxane (PDMS)-photoacoustic lens, were introduced to trigger the drug release from alginate microgels encapsulated with drug-loaded poly(lactic-co-glycolic acid) (PLGA) nanoparticles. We demonstrated the antibacterial capability of this drug delivery system against Escherichia coli by the disk diffusion method, and antitumor efficacy toward the HeLa cell-derived tumor spheroids in vitro. This novel LGFU-responsive drug delivery system provides a simple and remote approach to precisely control the release of therapeutics in a spatiotemporal manner and potentially suppress detrimental effects to the surrounding tissue, such as thermal ablation.}, journal={JOURNAL OF CONTROLLED RELEASE}, author={Di, Jin and Kim, Jinwook and Hu, Quanyin and Jiang, Xiaoning and Gu, Zhen}, year={2015}, month={Dec}, pages={592–599} }

Here we describe a wearable, tensile strain-triggered drug delivery device consisting of a stretchable elastomer and microgel depots containing drug loaded nanoparticles. By applying a tensile strain to the elastomer film, the release of drug from the microdepot is promoted due to the enlarged surface area for diffusion and Poisson's ratio-induced compression on the microdepot. Correspondingly, both sustained drug release by daily body motions and pulsatile release by intentional administration can be conveniently achieved. Our work demonstrated that the tensile strain, applied to the stretchable device, facilitated release of therapeutics from microdepots for anticancer and antibacterial treatments. Moreover, polymeric microneedles were further integrated with the stretch-responsive device for transcutaneous delivery of insulin and regulation of blood glucose levels of chemically induced type 1 diabetic mice.}, number={9}, journal={ACS NANO}, author={Di, Jin and Yao, Shanshan and Ye, Yanqi and Cui, Zheng and Yu, Jicheng and Ghosh, Tushar K. and Zhu, Yong and Gu, Zhen}, year={2015}, month={Sep}, pages={9407–9415} }

Glucose can passively transport across the bilayer membrane of the nanovesicle and be oxidized into gluconic acid by glucose oxidase, thereby causing a decrease in local pH. The acidic microenvironment causes the hydrolysis of the pH sensitive nanovesicle that in turn triggers the release of insulin in a glucose responsive fashion. In vitro studies validated that the release of insulin from nanovesicle was effectively correlated with the external glucose concentration. In vivo experiments, in which diabetic mice were subcutaneously administered with the nanovesicles, demonstrate that a single injection of the developed nanovesicle facilitated stabilization of the blood glucose levels in the normoglycemic state (<200 mg/dL) for up to 5 days.}, number={10}, journal={BIOMACROMOLECULES}, author={Tai, Wanyi and Mo, Ran and Di, Jin and Subramanian, Vinayak and Gu, Xiao and Buse, John B. and Gu, Zhen}, year={2014}, month={Oct}, pages={3495–3502} }

The traditional administration requires frequent subcutaneous insulin injections that are associated with poor patient compliance, including pain, local tissue necrosis, infection, and nerve damage. Taking advantage of emerging micro- and nanotechnologies, numerous alternative strategies integrated with chemical approaches for insulin delivery have been investigated. This review outlines recent developments in the controlled delivery of insulin, including oral, nasal, pulmonary, transdermal, subcutaneous and closed-loop insulin delivery. Perspectives from new materials, formulations and devices at the micro- or nano-scales are specifically surveyed. Advantages and limitations of current delivery methods, as well as future opportunities and challenges are also discussed.}, number={10}, journal={CHEMICAL SOCIETY REVIEWS}, author={Mo, Ran and Jiang, Tianyue and Di, Jin and Tai, Wanyi and Gu, Zhen}, year={2014}, pages={3595–3629} }
