Summary: Aplastic anemia is a rare but life-threatening disease characterized by low blood cell count and reduced cellularity in the bone marrow. Mesenchymal stem cell dysfunction is believed to play a role in the development of the disease. This review provides a comprehensive understanding of the involvement of mesenchymal stem cells in acquired idiopathic aplastic anemia and discusses their clinical application. The pathophysiology of the disease, properties of mesenchymal stem cells, and results of mesenchymal stem cell therapy in animal models are also described. The authors anticipate that more patients with aplastic anemia can benefit from mesenchymal stem cell therapy in the future.

Summary: The research proposes a simple method to induce neural differentiation of stem cells using ultrasound-driven piezoelectric materials to generate electrical signals on the surface, allowing stem cells to differentiate into neurons without the need for biological or chemical factors. The assessment at the gene and protein levels confirms the differentiation of stem cells into neuron-like cells.

Summary: This research suggests that the cell surface glycoprotein CD24 could serve as a selective biomarker for identifying subpopulations of BMSCs with varying osteogenic potential. CD24(pos) cells have increased expression of genes related to cell adhesion, motility, and extracellular matrix, while also showing reduced proliferation compared to CD24(neg) cells.

Summary: Myofibroblasts (MFB), derived from the fibroblast to myofibroblast transition (FMT), play a crucial role in pathologic fibrosis. Although MFBs were considered terminally differentiated cells, recent studies have shown their potential for de-differentiation, which could be therapeutically valuable for treating fibrotic diseases. This study investigated the MSC-mediated regulation of FMT and found that MSCs can reversibly de-differentiate MFBs into a group of fibroblast-like cells by inhibiting the TGF-beta-SMAD2/3 signaling pathway. These de-differentiated cells remain sensitive to TGF-beta 1 and may contribute to the progression of fibrotic diseases unless the pro-fibrotic microenvironment is corrected.

Summary: In this study, nano-deer bone meal was successfully prepared and found to have a higher Ca/P ratio and enriched beneficial trace elements compared to cow bone. The nano-deer bone meal showed good biocompatibility and met the standards of medical biomaterials. Cell function studies demonstrated its excellent performance in the proliferation and differentiation of bone marrow mesenchymal stem cells. These findings suggest the potential use of nano-deer bone meal as an active nanomaterial in bone tissue engineering.

Summary: Biomineralization is the process by which living organisms generate organized mineral crystals, especially in human cells the mechanism and propagation of the mineral remain largely unexplained and controversial. This study provides insight into the calcium depositions in human bone mesenchymal stem cells, suggesting a potentially redefined model for biomineralization.

Summary: Osteoporosis is characterized by low bone mass and degradation of bone tissue microarchitecture, leading to increased bone fragility and fracture risk. Our study found that BMSCs from ovariectomized rats had higher osteogenic and lipogenic differentiation capacity compared to the control group. Proteomics and transcriptome analysis showed differential expression of proteins and genes mainly involved in ECM-receptor interaction signaling pathway. These findings provide new insights for further research on the pathogenesis of osteoporosis.

Summary: ADSCs tend to spontaneously differentiate into neuron-like cells during high confluence culture, with enhanced expression of neuronal markers and neurotrophins, while BMSCs do not show this tendency. Additionally, ADSCs do not exhibit spontaneous adipogenic and osteogenic differentiation during this process.

Summary: Porous tantalum-based biomaterials have been widely used in bone defect repair due to their unique properties and excellent biocompatibility. BMSCs, as an important type of stem cells, have shown great potential in regulating the effects of porous tantalum. This study reviews the characteristics of porous tantalum-based biomaterials and the regulatory mechanisms on BMSCs, and discusses the feasibility of seeding BMSCs in porous tantalum-based biomaterials for tissue repair.

Summary: This study used resting-state functional magnetic resonance imaging to explore the relationship between individual's spontaneous neural activity and social interaction anxiety in a nonclinical population. The results showed that social interaction anxiety was correlated with the fractional amplitude of low-frequency fluctuations in several brain regions, and that emotional intelligence partially mediated this relationship. This study provides evidence for the neural basis of social interaction anxiety in the normal population and highlights the role of emotional intelligence in this anxiety.

Summary: This study provides morphometric data on the development of the human medullary arcuate nucleus (AN) by examining the brains of preterm and perinatal infants. The results show that AN morphology demonstrates asymmetry and individual variability during the fetal period. The volume and neuronal number of AN increase exponentially with age, while neuronal density decreases exponentially. The AN may undergo neuron death and neuroblasts production after mid-gestation.

Summary: Studies have shown that propofol-induced neurotoxicity is caused by disruption of mitochondrial fission and fusion, leading to an energy supply imbalance for developing neurons. Healthy mitochondria released by astrocytes can migrate to compromised neurons to mitigate propofol-induced neurotoxicity, but the exact mechanisms involved still need further clarification.

Summary: This study investigated the effects of alamandine on allodynia in a rat model and found the presence of MrgD receptors in the vlPAG and RVM regions. Microinjection of alamandine resulted in a significant increase in paw withdrawal threshold and could be blocked by an MrgD receptor antagonist. Upregulation of MrgD receptor expression following allodynia induction suggests a potential compensatory mechanism in response to pain.

Summary: The present study aimed to investigate the separate and combined effects of anodal transcranial direct current stimulation (tDCS) over the primary motor cortex (M1) and left dorsolateral prefrontal cortex (F3) regions on pain relief in patients with type-2 diabetes suffering from neuropathic pain (NP). The results showed that tDCS had the potential to induce pain relief in patients with type-2 diabetes suffering from NP. The mean perceived pain intensity in the posttest was lower in the M1 stimulation group than in the F3 stimulation group. However, more trials with larger sample sizes are necessary to define clinically relevant effects.

Summary: This study found a general impairment in humor comprehension in individuals with schizophrenia, with mental jokes being more difficult for both patients and controls. Humor comprehension was closely associated with the patients' overall pragmatic and linguistic profile, while the association with Theory of Mind (ToM) was minimal. Another notable finding was the increased appreciation of humor in individuals with schizophrenia, who rated jokes as funnier than controls did, regardless of whether they were correctly or incorrectly completed. The funniness ratings were not predicted by any measure, suggesting a dimension of humor untied to cognition or psychopathology.
