[Histonet] unidentified object

[S.Mason]

Hi folks,
 
Could anyone help me identify this object?

 
It was found just outside the epineurium in rat sciatic nerve and is surrounded by what I presume to be RBCs.  The staining is Passini's trichrome.
 
I have ruled out sutures, so does anyone have any ideas?  I would be most grateful to hear from you on s.mason <@t> open.ac.uk <mailto:s.mason <@t> open.ac.uk>  if you have.  I am away for a week so I apologise in advance if I don't reply immediately.
 
Thank you for your interest.
 
Kind regards,
