Synergic Neuroprotection Between Hort and Borneol Against Ischemic Stroke by Neurogenesis Modulating Reactive Astrogliosis and Maintaining the Blood-Brain Barrier.

Front Pharmacol 2021 16;12:666790. Epub 2021 Jun 16.

Jiangsu Key Laboratory for Pharmacology and Safety Evaluation of Chinese Materia Medica, Nanjing University of Chinese Medicine, Nanjing, China.

Hort (LCH) is a famous ethnomedicine in Asia known for its excellent output on stroke treatment, and borneol usually acts as an assistant for its reducing permeability of the blood-brain barrier (BBB) after stroke. Although their synergy against brain ischemia was verified in previous studies, the potential mechanism is still unknown.

Differentiation of Porcine Induced Pluripotent Stem Cells (piPSCs) into Neural Progenitor Cells (NPCs).

J Vis Exp 2021 Jun 11(172). Epub 2021 Jun 11.

Department of Surgery, Faculty of Veterinary Medicine and Animal Sciences, University of São Paulo; Department of Veterinary Medicine, Faculty of Animal Sciences and Food Engineering, University of São Paulo;

iPSC-derived neurons are attractive in vitro models to study neurogenesis and early phenotypic changes in mental illness, mainly when most animal models used in pre-clinical research, such as rodents, are not able to meet the criteria to translate the findings to the clinic. Non-human primates, canines, and porcine are considered more adequate models for biomedical research and drug development purposes, mainly due to their physiological, genetic, and anatomical similarities to humans. The swine model has gained particular interest in translational neuroscience, enabling safety and allotransplantation testing. Read More

Differential expression of stem cell markers in proliferating cells in glioma.

J Cancer Res Clin Oncol 2021 Jun 25. Epub 2021 Jun 25.

Institute of Neuropathology, University Medical Center Hamburg-Eppendorf, Martinistrasse 52, 20246, Hamburg, Germany.

Purpose: The identification of prognostically and therapeutically relevant molecular markers is fundamental to the further development of personalised therapies in brain tumours. Current therapeutic options for the treatment of gliomas rely mainly on surgical resection and the inhibition of tumour cell proliferation by irradiation and chemotherapy. Glioma stem cells are a subpopulation of proliferating tumour cells that have self-renewal capacity and can give rise to heterogeneous cells that comprise the tumour and are thought to play a role in the resistance of gliomas to therapy.

Neural stem cells in the adult olfactory bulb core generate mature neurons in vivo.

Stem Cells 2021 May 8. Epub 2021 May 8.

Instituto Cajal-Consejo Superior de Investigaciones Científicas (CSIC), Madrid, Spain.

Although previous studies suggest that neural stem cells (NSCs) exist in the adult olfactory bulb (OB), their location, identity, and capacity to generate mature neurons in vivo has been little explored. Here, we injected enhanced green fluorescent protein (EGFP)-expressing retroviral particles into the OB core of adult mice to label dividing cells and to track the differentiation/maturation of any neurons they might generate. EGFP-labeled cells initially expressed adult NSC markers on days 1 to 3 postinjection (dpi), including Nestin, GLAST, Sox2, Prominin-1, and GFAP. Read More
