Mouse hindlimb microdissections. 11.5 dpc, 12.5 dpc, and 13.5 dpc mouse hindlimb cryosections stained with Toluidine Blue. Upper panels (A-C) show intact tissue; lower panels (D-F) show cryosections following microdissection of tibial and fibular tissues. Staining of tissues shown in lower panels was performed following microdissection. T = Tibia, F = Fibula. Scale bar = 500 μm.
