Figure 2

The secondary giant trophoblast cells of the field vole Microtus rossiameridionalis at 10th (a, b) and 14th (c-f) day pc. a – a nucleus of a giant trophoblast cell of network structure (endointerphase), the elongated GCB (GCB) with signs of disc patterns characteristical of polytene chromosomes; b – a nucleus of a giant trophoblast cell with bundles of polytene chromosomes (endoprophase); GCBs are different of these bundles by higher degree of condensation; c-f – nuclei of the secondary giant trophoblast cells with 1–2 GCBs and a great number of endomitotic chromosomes (asterisks). Feulgen staining. Bar is 10 μm.
