Just fix them in NBF, embed in paraffin, and do an H&E. Collagen gels
stain very lightly in an H&E and the fibroblasts will stain dark with the
hematoxylin. You shouldn't have any problem seeing/counting the
fibroblasts. Any problems, ask me about it; collagen matrices of one kind
or another account for the bulk of my lab's work.   jc
