Mouse Meiotic Prophase I Stages

Representative immunofluorescence images showing synaptonemal complex 3 protein (Scp3) organization on nuclear spreads at different stages of meiotic prophase I made on cultured spermatogonia.

Scale bar, 10 µm.


Leptotene

  • leptotene phase, leptonema; Greek, leptotene = "thin threads"
  • the duplicated paired chromosome homologs condense.

Zygotene

  • zygotene phase, zygonema, Greek, zygotene = "paired threads"
  • homologous chromosomes become closely associated (synapsis) to form pairs of chromosomes consisting of four chromatids (tetrads).
  • the synaptonemal complex begins to form between the two sets of sister chromatids in each bivalent (the duplicated chromosome paired with its homologous duplicated chromosome).
