Table 2 Sub-cellular distribution of FGF and GFG immunoreactivity in rat tissues. Immunohistochemistry was performed as described in Materials and Methods. Tissues were scored as negative, -; a trace, (+); positive, +; or strongly positive, ++.

From: Alternative splicing and differential subcellular localization of the rat FGF antisense gene product
