Collaborating teams from @Department of Physiology, Anatomy and Genetics and @Department of Chemistry at University of Oxford engineered 3D microfluidic constructs containing human neuronal progenitor cells (NPCs) cultured either alone or together with mouse astrocytes. 
The results were striking. Compared to NPCs alone, co-cultures exhibited:
Enhanced neuronal maturation
Increased cell viability and density
Reduced lesion size after implantation
Greater axonal outgrowth
Improved astrocyte coupling to blood vessels within the graft.
High-resolution deconvolved microscopy confirmed the presence of synapses within the implants, while optogenetic experiments demonstrated functional connections between host brain tissue and the transplanted constructs.
Both NPC-only and co-culture grafts increased astrocyte size, but co-cultures demonstrated superior structural and functional outcomes overall, underscoring the importance of astrocyte–neuron interactions from the outset.

The research was done with support from the Oxford Martin School- https://www.oxfordmartin.ox.ac.uk/brain-repair Oxford Martin School

have ppl encountered any IP problems getting to use any of the tools we've made? GCaMP? RCaMP, SnFRs, AAVretro, etc.? we tried to make access trivial and cheap. but if there are problems, please let me know. we could try to break patents on all those to make shareware versions, if this is a problem

Even though, for each manuscript, time under review is only 7–15 days longer for female- than for male-authored articles (Fig 2), accumulated over a woman’s career, these delays can be very substantial. For instance, for every 50 papers published by a female author, she will have spent on average 350–750 days longer than her male counterparts waiting for reviews and editorial decisions and/or revising manuscripts.

"Biomedical and life science articles by female researchers spend longer under review" from @plosbiology.org. After I read this sentence, I counted & I have 43 papers w/ a female first and/or last author. Lots of time wasted in longer reviews/revisions. πŸ˜•
