Simultaneous determinations of DNA content in cell nuclei and condensed chromatin bodies formed by heterochromatized regions of sex chromosomes (gonosomal chromatin bodies, GCB) have been performed in two trophoblast cell populations of the East-European field vole Microtus rossiaemeridionalis: in the proliferative population of trophoblast cells of the… (More)
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.
