AI Article Synopsis
Article Abstract
Aim: The aim of this study was to evaluate the clinical safety, feasibility and efficacy of transplantation of neural precursor cells (NPCs) in the treatment for Parkinson's disease (PD).
Material And Methods: Twenty-one patients, aged 42-79 years (median age 57.33 years), participated in the study. A total of 3 × 107 NPCs in 0.25 ml were deposited unilaterally into the striatum. To access the effectiveness of first transplantation surgery, comparisons between the resulting pre-first surgery evaluation and pre-second surgery evaluation were made with repeatedmeasures analysis of variance. Unified Parkinson's Disease Rating Scale (UPDRS), Hoehn-Yahr, PDQ-39 and Schwab-England Scores were used to evaluate the Parkinson patients' neurofunctions. Four aspects were used to assess the possible side effects of transplantation: a) tumor formation, b) immune rejection and use of immunosuppressant, c) graft induced complication and d) delivery related side effects.
Results: This study demonstrated that the symptoms of PD patients were statistically improved after transplantation (P < 0.01). There were no obvious side effects of transplantation.
Conclusion: Transplantation of neural precursor cells may be a valid and safe treatment method for Parkinson's Disease.

Poly (lactic-co-glycolic acid) (PLGA) is an important biomaterial for tissue defect repair, but its application in replacing missing brain tissue needs improvement. Mesenchymal stem cells (MSCs) have been used to treat various neurological diseases, but they face challenges when filling large tissue defects. The purpose of this study was to investigate the effects of PLGA combined with MSCs transplantation on brain structure and neural function in rats with traumatic brain injury (TBI), and explore its possible mechanism.

Background & Aims: Biliary abnormalities in autoimmune hepatitis (AIH) and interface hepatitis in primary biliary cholangitis (PBC) occur frequently, and misinterpretation may lead to therapeutic mistakes with a negative impact on patients. This study investigates the use of a deep learning (DL)-based pipeline for the diagnosis of AIH and PBC to aid differential diagnosis.
Methods: We conducted a multicenter study across six European referral centers, and built a library of digitized liver biopsy slides dating from 1997 to 2023.

Fragile X syndrome (FXS) is an inherited neurodevelopmental disorder characterized by a range of clinical manifestations with no effective treatment strategy to date. Here, transplantation of GABAergic precursor cells from the medial ganglionic eminence (MGE) is demonstrated to significantly improve cognitive performance in Fmr1 knockout (KO) mice. Within the hippocampus of Fmr1-KO mice, MGE-derived cells from wild-type donor mice survive, migrate, differentiate into functionally mature interneurons, and form inhibitory synaptic connections with host pyramidal neurons.

Facilitating neuronal differentiation of stem cells and microenvironment remodeling are the key challenges in cell-based transplantation strategies for central nervous system regeneration. Herein, the study harnesses the intrinsic pro-neural differentiation potential of nerve-derived extracellular matrix (NDEM) and its specific affinity for cytokines to develop an NDEM-gelatin methacryloyl(gelMA)-based bifunctional hydrogel delivery system for stem cells and cytokines. This system promotes the neural differentiation of bone marrow stromal cells (BMSCs) and optimizes the therapeutic index of Interleukin-4 (IL-4) for spinal cord injury (SCI) treatment.

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative malady that causes progressive degeneration and loss of motor neuron function in the brain and spinal cord, eventually resulting in muscular atrophy, paralysis, and death. Neural stem/progenitor cell (NSPC) transplantation can improve bodily function in animals and delay disease progression in patients with ALS. This paper summarizes and analyzes the efficacy and safety of neural stem/progenitor cell (NSPC) transplantation as a treatment for ALS, aiming to improve function and delay disease progression in patients.
