In vivo imaging of hematopoietic stem cell development in the zebrafish

Panpan Zhang, Feng Liu

Frontiers of Medicine 2011, Volume 5, Issue 3,   Pages 239-247 doi: 10.1007/s11684-011-0123-0

Abstract: imaging is crucial for developmental biology and can further help to follow cell development/differentiation in normal and pathological conditions. Recent advances in optical imaging techniques has facilitated tracing of the developmental dynamics of a specific organ, tissue, or even a single cell. The zebrafish is an excellent model for imaging of hematopoiesis due to its transparent embryo at early stage; moreover, different zebrafish hematopoietic stem cells (HSCs) transgenic lines have been demonstrated as very useful tools for illustrating the details of the HSC developmental process. In this review, we summarize recent studies related to the non-invasive imaging of HSC transgenics, to show that zebrafish transgenic lines are powerful tools for developmental biology and disease. At the end of the review, the perspective and some open questions in this field will be discussed.

molecule fluorescent probes for simultaneous imaging of two bioactive molecules in live cells and in vivo

Yongqing Zhou, Xin Wang, Wei Zhang, Bo Tang, Ping Li

Frontiers of Chemical Science and Engineering 2022, Volume 16, Issue 1,   Pages 4-33 doi: 10.1007/s11705-021-2041-2

Abstract: The interrelationships and synergistic regulations of bioactive molecules play pivotal roles in physiological and pathological processes involved in the initiation and development of some diseases, such as cancer and neurodegenerative and cardiovascular diseases. Therefore, the simultaneous, accurate and timely detection of two bioactive molecules is crucial to explore their roles and pathological mechanisms in related diseases. Fluorescence imaging associated with small molecular probes has been widely used in the imaging of bioactive molecules in living cells and due to its excellent performances, including high sensitivity and selectivity, noninvasive properties, real-time and high spatial temporal resolution. Single organic molecule fluorescent probes have been successively developed to simultaneously monitor two biomolecules to uncover their synergistic relationships in living systems. Hence, in this review, we focus on summarizing the design strategies, classifications, and bioimaging applications of dual-response fluorescent probes over the past decade. Furthermore, future research directions in this field are proposed.

Positive ion activated rapid addition and mitochondrial targeting ratiometric fluorescent probes for in vivo

Yan Shi, Fangjun Huo, Yongkang Yue, Caixia Yin

Frontiers of Chemical Science and Engineering 2022, Volume 16, Issue 1,   Pages 64-71 doi: 10.1007/s11705-021-2048-8

Abstract: Heterocyclic compound quinoline and its derivatives exist in natural compounds and have a broad spectrum of biological activity. They play an important role in the design of new structural entities for medical applications. Similarly, indoles and their derivatives are found widely in nature. Amino acids, alkaloids and auxin are all derivatives of indoles, as are dyes, and their condensation with aldehydes makes it easy to construct reaction sites for nucleophilic addition agents. In this work, we combine these two groups organically to construct a rapid response site (within 30 s) for H S, and at the same time, a ratiometric fluorescence response is presented throughout the process of H S detection. As such, the lower detection limit can reach 55.7 nmol/L for H S. In addition, cell imaging shows that this probe can be used for the mitochondrial targeted detection of endogenous and exogenous H S. Finally, this probe application was verified by imaging H S in nude mice.

Oral product input to the GI tract: GIS an oral product performance technology

Gordon L. Amidon, Yasuhiro Tsume

Frontiers of Chemical Science and Engineering 2017, Volume 11, Issue 4,   Pages 516-520 doi: 10.1007/s11705-017-1658-7

Abstract: The patient receives a pharmaceutical product, not a drug. The pharmaceutical products are formulated with a drug, an active ingredient to produce the maximum therapeutic effect after oral absorption. Therefore, it is the product we must optimize for the patients. In order to assure the safety and efficacy of pharmaceutical products, we need an predictive tool for oral product performance in patients. Currently, we are a surprisingly long way from accomplishing that objective. If the 20th century was the ‘age of the drug’, i.e., the ‘magic bullet’, the 21st century must become the ‘age of the guided missile’, i.e., the delivery system, including the form of the active pharmaceutical ingredient (API) (‘drug’). The physical form of the drug and the delivery system must be optimized to maximize the therapeutic benefits of pharmaceutical products for humans. Oral immediate release (IR) dosage forms cannot be optimal for all drugs or likely even any drugs (APIs). Still, the formulation of pharmaceutical products has to be optimized for patients. But how do we optimize oral delivery of drugs? It is usually through ‘trial and error’, in humans! We need a better way to optimize the oral dosage forms. We have suggested to select different dissolution methodologies for this optimization based on BCS Subclasses. In this article, we present the predicted drug dissolution profile of ketoconazole as a model drug from our laboratory utilizing a gastrointestinal simulator (GIS), which is an adaptation of the ASD system. GIS consists of three chambers representing stomach, duodenum, and jejunum, to create the human gastrointestinal tract-like environment and enable the control the gastric emptying rate. This dissolution system allows the monitoring of the drug dissolution phenomena and the observation of the supersaturation and the precipitation of pharmaceutical products, which is useful information to predict dissolution of pharmaceutical products. This system can provide the actual input needed to accurately predict the input into the systemic circulation required by many of the absorption prediction packages available today.

Abstract:

Controlling the immune response with only clinically approved immunosuppressant drugs is difficult in renal heterotransplantation from pigs to nonhuman primates. Moreover, to the best of our knowledge, no reports exist on the use of fetal pigs as kidney donors. This study aimed to compare the degree of transplant rejection between neonatal and fetal kidneys, with genetically unmodified pigs as donors and cynomolgus monkeys as recipients. The left kidneys of the recipient monkeys were removed, followed by transplantation of neonatal as well as fetal pig kidneys, which had undergone vascular anastomosis at the same site, into the retroperitoneum. Immunosuppression was performed with only US Food and Drug Administration-approved drugs. The fetal kidneys were transplanted into the omentum and paraaortic regions of cynomolgus monkeys. Consequently, the engraftment and development of the transplanted tissues were pathologically examined by sampling over time (twice in each experiment). An acute rejection was observed after a few weeks in neonatal renal grafts with vascular anastomosis. However, fetal pig kidneys were spared from rejection despite the administration of the same immunosuppressive protocol to the monkeys and the recipient blood vessels flowing into the fetal kidneys. The immunogenicity of fetal kidneys in pig–monkey renal heterotransplantation was lower than that of neonatal kidneys.
