Time-Lapse Dynamics of the Mouse Oocyte Chromatin Organisation during Meiotic Resumption
Figure 1
Time-lapse imaging during the first 120 minutes of oocyte culture. (a) SN oocyte, (a–p) bright field; (a’–p’) UV fluorescence describing the changes to the Ho-positive chromatin within the nucleus. Arrow in (e) and (d) shows increase of perivitelline space. Arrowhead in (l’) enlargement thread-like chromatin structures is visible among the pericentromeric CHCs. (b) NSN oocyte, (a–p) bright field; (a’–p’) UV fluorescence. Bar: 40 μm.
