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.
