Fig. 2
In situ hybridization of esco2 in fin cryosections. Left: Cryosection from a whole-mount WT-5 dpa fin treated for in situ hybridization showing tissue specific expression of esco2 mRNA within the blastema compartment. Right: In situ hybridization was completed on a WT-5 dpa fin cryosection showing a similar pattern of esco2 expression localized specifically at the blastemal region. Arrows indicate esco2 expression at blastema. B, blastemal; e, epidermis; m, mesenchyme. Scale bar = 50 µm.
