Figure 7. Representative Ca²⁺ oscillatory patterns in Sr²⁺-induced MII oocytes.

Changes in the fluorescence of a Ca²⁺ indicator dye in mouse oocytes followed by incubation in Sr²⁺-containing medium revealed the almost normal pattern of Ca²⁺ oscillations in the control (A) and buffer-injected sham control (B) MII oocytes. However, Gas6-silence MII oocytes (C) exhibited both normal and abnormal patterns of Ca²⁺ oscillations. N, normal Ca²⁺ oscillatory pattern; Ab, abnormal Ca²⁺ oscillatory pattern.
