Endothelial progenitor cells influence acute and subacute stroke hemodynamics
Endothelial Progenitor Cells (EPCs) are a circulating stem cell population with in vivo capacity of promoting angiogenesis after ischemic events. Despite the promising preclinical data, their potential integration with reperfusion therapies and hemodynamic evolution of stroke patients is still unknown. Our aim was to determine the association of EPCs with acute, subacute and chronic hemodynamic features.

New spectrum of the neurologic consequences of Zika
Zika virus infection represents a new neuropathological agent with association to a wide spectrum of neurological complications: a) Congenital Zika Syndrome by affecting the neural stem cells of the human fetal brain; b) Guillain-Barr é Syndrome by an autoimmune response against peripheral myelin and/or axonal components or probable direct inflammatory reaction; c) Encephalitis/meningoencephalitis and myelitis by a direct viral inflammatory process on the central nervous system; d) Sensory neuropathy by infecting directly the pe ripheral neurons and causing substantial cell death and pathogenic transcriptional dysregulati...

Protective effects of ginsenoside Rg1 against oxygen-glucose-deprivation-induced apoptosis in neural stem cells
Oxygen-glucose deprivation (OGD) causes neural damages through stroke-induced ischemia. Neural stem cells (NSCs) have been shown to alleviate ischemia-induced neural damages. However, ischemia reduces NSC survival. Ginsenoside Rg1 exerts anti-inflammatory and anti-oxidative effects, and repairs brain injury-related neural damages. We aimed to investigate whether ginsenoside Rg1 could prevent NSCs from OGD insult. Using multiple techniques, we explored neuroprotective effects of ginsenoside Rg1 on OGD-insulted NSCs.

The potential use of mesenchymal stem cells in stroke therapy - from bench to bedside
Stroke is the second main cause of morbidity and mortality worldwide. The rationale for the use of mesenchymal stem cells (MSCs) in stroke is based on the capacity of MSCs to secrete a large variety of bioactive molecules such as growth factors, cytokines and chemokines leading to reduction of inflammation, increased neurogenesis from the germinative niches of central nervous system, increased angiogenesis, effects on astrocytes, oligodendrocytes and axons. This review presents the data derived from experimental studies and the evidence available from clinical trials about the use of MSCs in stroke therapy.
