VIB scientists discover neuron-producing stem cells in the membranes covering the brain: possible implications for brain regeneration?

How is your doctor and stroke hospital encouraging/sponsoring research to make this knowledge usable for stroke recovery. ANYTHING AT ALL?  Or are they continuing to sit on their asses doing NOTHING?

In a cross-domain study directed by professor Peter Carmeliet (VIB – KU Leuven), researchers discovered unexpected cells in the protective membranes that enclose the brain, the so called meninges. These ‘neural progenitors’ – or stem cells that differentiate into different kinds of neurons – are produced during embryonic development. These findings show that the neural progenitors found in the meninges produce new neurons after birth – highlighting the importance of meningeal tissue as well as these cells’ potential in the development of new therapies for brain damage or neurodegeneration. A paper highlighting the results was published in the leading scientific journal Cell Stem Cell.
Scientists’ understanding of brain plasticity, or the ability of the brain to grow, develop, recover from injuries and adapt to changing conditions throughout our lives, has been greatly broadened in recent years. Before the discoveries of the last few decades, neurologists once thought that the brain became ‘static’ after childhood. This dogma has changed, with researchers finding more and more evidence that the brain is capable of healing and regenerating in adulthood, thanks to the presence of stem cells. However, neuronal stem cells were generally believed to only reside within the brain tissue, not in the membranes surrounding it.
The meninges: unappreciated no more: Believed in the past to serve a mainly protective function to dampen mechanical shocks, the meninges have been historically underappreciated by science as having neurological importance in its own right. The data gathered by the team challenges the current idea that neural precursors – or stem cells that give rise to neurons – can only be found inside actual brain tissue.
Prof. Peter Carmeliet (VIB-KU Leuven): “The neuronal stems cells that we discovered inside the meninges differentiate to full neurons, electrically-active and functionally integrated into the neuronal circuit. To show that the stem cells reside in the meninges, we used the extremely powerful single-cell RNA sequencing technique, a very novel top-notch technique, capable of identifying the (complex gene expression signature) nature of individual cells in a previously unsurpassed manner, a première at VIB.”
Following up on future research avenues: When it comes to future leads for this discovery, the scientists also see possibilities for translation into clinical application, though future work is required.
Prof. Peter Carmeliet (VIB-KU Leuven): “An intriguing question is whether these neuronal stem cells in the meninges could lead to better therapies for brain damage or neurodegeneration. However, answering this question would require a better understanding of the molecular mechanisms that regulate the differentiation of these stem cells. How are these meningeal stem cells activated to become different kinds of neurons? Can we therapeutically ‘hijack’ their regeneration potential to restore dying neurons in, for example, Alzheimer’ Disease, Parkinson’s Disease, amyotrophic lateral sclerosis (ALS), and other neurodegenerative disorders? Also, can we isolate these neurogenic progenitors from the meninges at birth and use them for later transplantation? These findings open up very exciting research opportunities for the future.”
Unique funding opportunities: Moving into unchartered territory is high risk, and can offer high gain, but securing funding for such type of research is challenging. However, Carmeliet’s discoveries were made possible to a large extent by funding through “Opening the Future: pioneering without boundaries”, a recently created Mecenas Funding Campaign for funding of high risk brain research but with potential for breakthrough discoveries, started up by the KU Leuven in 2013 and unique in Flanders.
Prof. Peter Carmeliet (VIB-KU Leuven): “Being able to use such non-conventional funding channels is of utmost importance to break new boundaries in research. This unique Mecenas funding initiative by the KU Leuven is innovative and boundary-breaking by itself. Our entire team is enormously grateful for the opportunities it has created for our investigations”.

Meninges: from protective membrane to stem cell niche

This sounds important  but I'll have to leave the full 14 pages to researchers to propose uses for this knowledge.

Abstract: Meninges are a three tissue membrane primarily known as coverings of the brain. More in depth studies on
meningeal function and ultrastructure have recently changed the view of meninges as a merely protective membrane.
Accurate evaluation of the anatomical distribution in the CNS reveals that meninges largely penetrate inside
the neural tissue. Meninges enter the CNS by projecting between structures, in the stroma of choroid plexus and form
the perivascular space (Virchow-Robin) of every parenchymal vessel. Thus, meninges may modulate most of the
physiological and pathological events of the CNS throughout the life. Meninges are present since the very early embryonic
stages of cortical development and appear to be necessary for normal corticogenesis and brain structures
formation. In adulthood meninges contribute to neural tissue homeostasis by secreting several trophic factors including
FGF2 and SDF-1. Recently, for the first time, we have identified the presence of a stem cell population with neural
differentiation potential in meninges. In addition, we and other groups have further described the presence in meninges
of injury responsive neural precursors. In this review we will give a comprehensive view of meninges and their
multiple roles in the context of a functional network with the neural tissue. We will highlight the current literature on
the developmental feature of meninges and their role in cortical development. Moreover, we will elucidate the anatomical
distribution of the meninges and their trophic properties in adult CNS. Finally, we will emphasize recent evidences
suggesting the potential role of meninges as stem cell niche harbouring endogenous precursors that can be
activated by injury and are able to contribute to CNS parenchymal reaction.
