Summary: Bone marrow transplantation is a treatment for various diseases, and this study proposes a new method to evaluate the engraftment and behavior of hematopoietic stem cells. The method involves the use of bioluminescence imaging and inductively coupled plasma mass spectrometry associated with superparamagnetic iron oxide nanoparticles. The study found that the administration of Fluorouracil enriched the population of hematopoietic stem cells in the bone marrow, and labeling the cells with nanoparticles provided information on their internalization status. The study also utilized blood count and bioluminescence imaging to monitor the reconstitution of hematopoiesis and evaluate the transplantation effectiveness.

Summary: The study found that the use of MGO enhanced the effect of ESC-MSC-CM on reducing necrosis, inflammation, aspartate transaminase, alanine aminotransferase, and alkaline phosphatase in CCl4-induced rat liver failure. Treatment with MGO also upregulated the expression of vascular endothelial growth factor and matrix metalloproteinase-9 (MMP-9). Additionally, ESC-MSC-CM was more efficient compared to MSC-CM in protecting against acute liver damage.

Summary: In this study, a new microcarrier with hyaluronic acid (HA) as the core material was developed for scalable serum-free suspension culture of hESC-derived MSCs. The optimal microcarriers, with a coating collagen concentration of 100 μg/mL or concave-structured surface (cHAMCs), allowed for the expansion of IMRCs within six days with a high yield. The harvested cells showed high viability, immunomodulatory and regenerative therapeutic promise, as well as increased secretion of extracellular matrix (ECM).

Summary: Alzheimer's disease (AD) is a complex neurodegenerative disease with limited treatment options. Mesenchymal stem cell (MSC) therapy, with its ability to target multiple pathological mechanisms, has recently emerged as a potential novel treatment. However, the low brain retention efficiency of MSCs and the limited therapeutic abilities of autologous MSCs pose challenges to their effectiveness. In this study, we developed iron oxide nanoparticle (IONP)-incorporated human Wharton's jelly-derived MSCs (MSC-IONPs) to enhance their therapeutic potential. With the use of magnetic guidance, MSC-IONPs showed higher brain retention efficiency, leading to improved therapeutic efficacy in murine models of AD. Furthermore, allogeneic MSCs derived from human Wharton's jelly may offer superior therapeutic abilities compared to autologous MSCs in aged AD patients. This study provides a promising strategy for the development of MSC therapies for AD.

Summary: In this study, non-genetically modified Sertoli-like cells were successfully induced from mouse ESCs using defined protein factors, showing similar characteristics and functionality to natural Sertoli cells. However, the efficiency of the non-GM method was still lower compared to lentiviral transduction. This work lays a foundation for the future production of non-GM Sertoli-like cells for clinical applications and fundamental theory research.

Summary: The study synthesized NDG-Mn3O4 nanocomposite and tested its performance in photodynamic therapy (PDT) and magnetic resonance imaging (MRI) for cancer treatment. The results showed that NDG-Mn3O4 nanocomposite exhibited significant cytotoxicity in cancer cells under laser irradiation and increased generation of singlet oxygen proportional to the duration of laser irradiation. It also showed concentration-dependent enhancement of signal intensity in MRI. These findings suggest the potential application of NDG-Mn3O4 nanocomposites in cancer theranostics.

Summary: Ultrasound can deliver energy and control devices wirelessly and non-contactly, and it can propagate and focus in various mediums including biological tissue. Mechanoluminescent (ML) nanocrystal colloids activated by ultrasound provide a wireless method to remotely control a light source, such as a multicolor display. In this study, we synthesized ML colloids with bright blue emission under ultrasound using a biomineral-inspired suppressed dissolution approach, achieving small sizes down to 20 nm. By leveraging the bandgap engineering strategy of all-inorganic perovskite quantum dots (PQDs), we achieved wavelength tunability of the mechanoluminescence of ML colloid/PQD composites. The ultrasound-activated emission of the ML colloid/PQD composites exhibited a highly saturated color gamut covering the entire visible spectrum, enabling the demonstration of a flexible and wireless multicolor display with individually addressed pixels using scanning focused ultrasound.

Summary: Bioluminescence imaging (BLI) is an essential technique in biomedical research that allows non-invasive visualization of cells and biochemical events in living organisms. However, BLI in the central nervous system faces challenges due to the poor performance of luciferases and existing substrates. In this study, researchers discovered a NanoLuc substrate, cephalofurimazine (CFz), which improves the brain performance of BLI. CFz paired with Antares luciferase produces significantly higher signals in the brain compared to the standard combination of d-luciferin and firefly luciferase. This discovery enables high sensitivity imaging of the brain using NanoLuc-based indicators.

Summary: Light is widely used in life science for controlling and observing biological processes, but limited penetration depth of visible light has been a challenge for using light inside tissue. In the past decade, non-invasive deep-tissue light sources based on luminescent nanomaterials have been developed using photonics and materials science tools. This perspective provides an overview of intravital nanoscopic light sources, discussing their advantages over existing methods for in vivo light delivery, and highlighting their recent applications in optogenetics neuromodulation and fluorescent imaging in live animals. The feasibility of combining these non-invasive light sources with other modalities to expand the utilities of light in biology is also discussed.
