Nondestructive Characterization of Stem Cell Neurogenesis by a Magneto-Plasmonic Nanomaterial-Based Exosomal miRNA Detection

KiBum Article Pic Nondestructive Characterization of Stem CelltifThe full realization of stem cell-based treatments for neurodegenerative diseases requires precise control and characterization of stem cell fate. Recently, exosomes and their inner contents have been discovered to play critical roles in cell-cell interactions and intrinsic cellular regulations and have received wide attention as next-generation biomarkers. Moreover, exosomal microRNAs (miRNA) also offer an essential avenue for nondestructive molecular analyses of cell cytoplasm components.

Biosensors: NIR Biosensing of Neurotransmitters in Stem Cell‐Derived Neural Interface Using Advanced Core–Shell Upconversion Nanoparticles

KiBum Article Pic NIR Optical Biosensor for Dopamine DetectionNeurotransmitters, for instance dopamine (DA), are significant endogenous signals in the central nervous system (CNS), as they play vital roles in modulating neurophysiological processes including cognition, emotion, memory, and other behaviors. Therefore, fast, ultra-sensitive, non-destructive and robust detection of neurotransmitters during stem cell differentiation and neuromodulation processes in the CNS would be of paramount importance for gaining an insight into how neural interactions regulate brain functions, developing better molecular diagnostics and therapeutics for neurological disorders. To this end, upconversion nanoparticles (UCNPs) have recently gained extensive attention as optical biosensors due to their excellent photo-stability, narrow emission bandwidths, as well as high signal to noise ratio, showing great potential in various applications; however, the relatively weak luminescence intensity due to low quantum efficiencies compromises the further development of UCNP-based applications.

Overcoming Chemoresistance in Cancer Using Nanotechnology-based Drug Delivery

kibum article 3 000b0Chemoresistance is a major challenge facing the effective treatment of cancers. To overcome resistance to chemotherapy, microRNA (miRNA), which are short (20−22 nucleotides) noncoding RNA molecules, has shown to be an attractive strategy. A growing body of evidence shows that modulation of miRNA levels in cancer can mitigate the development and progression of cancer.

A Biodegradable Hybrid Inorganic Nanoscaffold for Advanced Stem Cell Therapy

mice d9d52

Considering the intrinsically limited regenerative capability of the central nervous system (CNS) and the complex inhibitory microenvironment of injured spinal cord, developing effective therapeutics for CNS diseases and injuries [e.g., Parkinson disease and spinal cord injury (SCI)] has been challenging. To this end, stem cell therapy can provide a promising solution. Neural stem cells can differentiate into neurons and restore the damaged neuronal circuits. Additionally, stem cells modulate the inhibitory microenvironment at the site of CNS disease and injury through the secretion of trophic factors. Nevertheless, the low survival rate and incomplete differentiation control of stem cells in vivo are critical barriers for the full realization of stem cell therapy potential. As such, there is an urgent need to develop an innovative approach to enhance stem cell transplantation and to control stem cell fate precisely.
