Sheep Oocyte Preantral Follicle Distribution of TERT

Oocytes derived from a preantral (PA) follicle.

  • TERT - Red (Cy3-conjugated secondary antibody) (telomerase reverse transcriptase, TERT)
  • DNA - Green (SYBR Green 14/I)

Cropped, resized and relabelled from full figure.

Examples of oocyte TERT distribution, visualized with Cy3-conjugated secondary antibody (red), while DNA was counterstained in green with SYBR Green 14/I. TERT sub-cellular localization was influenced by chromatin configuration in all in vitro and in vivo classes of germ cells analyzed. (A,B) Oocytes derived from a preantral (PA) follicle (A) and an in vitro grown early antral (EA) follicle (B) with a not surrounded nucleolus (NSN) chromatin configuration which localized TERT in the nucleus. (C) in vitro grown oocyte derived from an EA follicle with a surrounded nucleolus (SN) chromatin configuration which reveals TERT between the nucleus and ooplasm. (D) Oocyte of a preovulatory follicle with condensed chromatin localized surrounding the nucleolus and the nuclear envelope (SNE configuration) and with a clear subcortical and perinuclear cytoplasmatic TERT distribution. Scale bar = 25 µm.
