Multiplexed FISH. Two sequential rounds of v3.HCR-FISH performed on a
regenerating axolotl limb tissue section. The DAPI image is shown for reference
(a) along with four genes stained in round 1:
Midkine (Mdk) (b),
Keratin 5 (Krt5) (c),
Axolotl anterior gradient (Aag)
(d), Thrombospondin 1 (Thbs1)
(e) and an overlay of all four genes (f). Four
genes stained in round 2: Hyaluronan And Proteoglycan Link Protein
3 (g), Keratin 17 (h),
Methyltransferase-like (i), Laminin
beta 1 (j) and an overlay of all 4 genes
(k). 50-μm scale bar is included on DAPI image and a
dotted line represents the epithelium/mesenchyme boundary
