Numerous strategies have been managed to improve functional recovery after spinal cord injury (SCI) but an optimal strategy doesn't exist yet. Actually, it is the complexity of the injured spinal cord pathophysiology that begets the multifactorial approaches assessed to favour tissue protection, axonal regrowth and functional recovery. In this context, it appears that mesenchymal stem cells (MSCs) could take an interesting part. The aim of this study is to graft MSCs after a spinal cord compression injury in adult rat to assess their effect on functional recovery and to highlight their mechanisms of action. We found that in intravenously grafted animals, MSCs induce, as early as 1 week after the graft, an improvement of their open field and grid navigation scores compared to control animals. At the histological analysis of their dissected spinal cord, no MSCs were found within the host despite their BrdU labelling performed before the graft, whatever the delay observed: 7, 14 or 21 days. However, a cytokine array performed on spinal cord extracts 3 days after MSC graft reveals a significant increase of NGF expression in the injured tissue. Also, a significant tissue sparing effect of MSC graft was observed. Finally, we also show that MSCs promote vascularisation, as the density of blood vessels within the lesioned area was higher in grafted rats. In conclusion, we bring here some new evidences that MSCs most likely act throughout their secretions and not via their own integration/differentiation within the host tissue.

re: Chronic utis & bacteriall vaginitus/ trichomunus [ metronizadole? ]
Research in past[ Prof Moorhead kidneys & Brumfitt [ urology] Royal Free
showed spina bifida GPs say occulta but results 1969 didn't mention what
kind.My mobility lifting & carrying poor but suspect connected to breathing
/ heart [ cardiac arrest] due to not following up.
Cupping [ acupuncture] caused a bruise on sacrum [ where spina bifida is]
but GPs are looking me in the face saying osteo /spasm giving medication
that has no effect.Also have CFS / fibro .
I am having the acute problem of episodes of temporary acute pain & near
paralysis caused by chronic utis 3 weekly [ out of Profs control [ not his
remit] relieved with paramol ,acupuncture & adding to uti medication which
can stop within hours but taking longer each time.Now can't get paramol.
The last time I had acute episodes of symptons[ different] resulted in
cardiac arrest as a result never having seen a cardiologist.There is a
possible genetic multi infart dementia connection [ Mother has severely]
What I need patient orientated researchers. Any trials? Stem cells to stop
infections getting to spine?
Maybe I could be the first human as pain excrutiating I don't want it to become chronic with the paralysis .
