I had similar strange in situ hybridization results, but decided that
they were interesting so I published them.  Using a probe to exons 2
and 3 of Fibroblast Growth Factor 2, I got slightly different signals
from the sense and the antisense probes. I ended up doing Ribonuclease
Protection Assays to show that they were very real and different
messages.  This is published as:  Savage, M.P. and J.F. Fallon (1995)
FGF-2 mRNA and its antisense message are expressed in a developmentally
specific manner in the chick limb bud and mesonephros.  Developmental
Dynamics 202:343-353.  Two other references,  Borja et al. (1993) 
Developmental Biol. 157:110-118,  and  Kimelman, D.(1992) In: Gene
Regulation: Biology of Antisense RNA and DNA  eds. Erickson, R.P. and
Izant, J.G.  New York: Raven Press, Ltd have been published on the same
system.  There are starting to be more papers out there, but they are
hard to find.
