miR-145-5p inhibits the proliferation of glioma stem cells by targeting translationally controlled tumor protein.

Glioma stem cells (GSCs) have potential for proliferation, self-renewal, and differentiation-the properties that play decisive roles in the process of malignancy in glioma. MicroRNAs (miRNAs) have been shown to regulate the characteristics of cancer stem cells. In this study, we show that miR-145-5p, a recently discovered miRNA, is expressed at low levels in primary GSCs (pGSCs).

Ultra-Stretchable and Fast Self-Healing Ionic Hydrogel in Cryogenic Environments for Artificial Nerve Fiber.

Self-healing materials behave with irreplaceable advantages in biomimetic intelligent robots (BIR) for avoiding or reducing safety hazards and economic losses from accidental damage during service. However, the self-healing ability is unreservedly lost and even becomes rigid and fragile in the cryogenic environment where BIR are precisely needed. Here, the authors report a versatile ionic hydrogel with fast self-healing ability, ultra-stretchability, and stable conductivity, even at -80 °C.

A case report on intermediate-grade malignant meningeal melanocytoma with elevated cell proliferation index.

Meningeal melanocytoma is a kind of extremely rare pigmented tumor of the central nervous system, which often occurs in the groove around the base of the brain and spinal pia mater. Age of onset is 40 to 50 years old, mostly presenting a benign course of disease and the prognosis is good. Case reports of partial invasion or metastasis from lesions are even rarer.

Intra-arterial delivery of human bone marrow mesenchymal stem cells is a safe and effective way to treat cerebral ischemia in rats.

Cerebral ischemic stroke is a very common condition that can cause death and disability. Studies have confirmed that stem cells have therapeutic effects if administered after a stroke. There is still a great deal of debate regarding the best route for cell transplantation.

TIMP1 in conditioned media of human adipose stromal cells protects neurons against oxygen-glucose deprivation injury.

Adipose stromal cells (ASC) can protect neurons when administered to brains due to secreted trophic factors. Our previous studies demonstrated that several neurotrophic factors such as brain-derived neurotropic factor (BDNF) and insulin like growth factor-1 (IGF-1) in ASC conditioned media (ASC-CM) can protect brains against hypoxic-ischemic (HI) injury in neonatal rats. In this study, we demonstrated that human ASC-CM potently blockeds caspase-3 mediated cortical neuronal apoptosis under in vitro oxygen-glucose deprivation (OGD).
