- It is also strongly expressed in spermatogonia and in primary spermatocytes of adult testis, but not in post-meiotic cells or testicular somatic cells.
- In addition, GJA1 can be found in the Leydig cells and seminiferous tubules between Sertoli cells and spermatogonia or primary spermatocytes, where it plays a key role in spermatogenesis and testis development through controlling the tight junction proteins in the blood-testis barrier.
- "Type B spermatogonia" undergo mitosis to produce diploid intermediate cells called primary spermatocytes.
- This is in contrast to male primordial germ cells which are arrested in the spermatogonial stage at birth and do not enter into spermatogenesis and meiosis to produce primary spermatocytes until puberty in the adult male.
- Primary spermatocytes are diploid (2N) cells. After meiosis I, two secondary spermatocytes are formed. Secondary spermatocytes are haploid (N) cells that contain half the number of chromosomes.
- Male germ-line stem cells divide asymmetrically to give one stem cell and a spermatogonia cell (unspecialised male germ cell) that undergoes mitotic proliferation to form primary spermatocytes (diploid - 46 chromosomes in the human).
- Type A cells replenish the stem cells, and type B cells differentiate into primary spermatocytes.
