Postnatal development of bovine Sertoli cells
Anatomy and Embryology
|January 1, 1986
Summary
Bovine Sertoli cell development shows significant morphological and functional changes from birth to 40 weeks. Key maturation stages, including the blood-testis barrier formation, occur within the first 28 weeks.
Area of Science:
- Reproductive Biology
- Cell Biology
- Histology
Background:
- Sertoli cells are crucial for spermatogenesis and testicular function.
- Understanding Sertoli cell development is key to reproductive health research.
Purpose of the Study:
- To investigate the morphological and functional development of bovine Sertoli cells postnatally.
- To correlate cellular changes with the acquisition of adult morphology and function.
Main Methods:
- Histological examination of bovine testicular tissue.
- Observation of Sertoli cell fine structure from 4 to 40 weeks postnatum.
Main Results:
- Tubular size increases due to cell proliferation and expansion in early weeks, then solely germ cell increase.
- Sertoli cells differentiate morphologically, with organelle changes and surface specialization, completing by 28 weeks.
- Inter-Sertoli junctions suggest blood-testis barrier formation by 24 weeks; high early secretory activity is noted.
Conclusions:
- Bovine Sertoli cell maturation is a prolonged process involving significant morphological and functional differentiation.
- The development of the blood-testis barrier is a critical milestone in postnatal testicular development.
- Early secretory activity of Sertoli cells may influence basal lamina formation and remodeling.

01:41Spermatogenesis
Spermatogenesis is the process by which haploid sperm cells are produced in the male testes. It starts with stem cells located close to the outer rim of seminiferous tubules. These spermatogonial stem cells divide asymmetrically to give rise to additional stem cells (meaning that these structures “self-renew”), as well as sperm progenitors, called spermatocytes. Importantly, this method of asymmetric mitotic division maintains a population of spermatogonial stem cells in the male reproductive...
01:10Zygotic Development And Stem Cell Formation
The development of all multicellular organisms starts with the fusion of haploid cells called sperm and egg to form a diploid zygote. A zygote is a totipotent cell that can develop into a complete organism. The zygote undergoes cell division or cleavage to form an 8-cell mass. Until this stage, the cells are spherical, loosely attached, and remain totipotent. Totipotent cells are capable of developing both the embryonic and the extraembryonic tissues. However, as they continue to divide, they...
01:22Spermatogenesis
Spermatogenesis is a complex process that involves the development of sperm cells from undifferentiated stem cells in the seminiferous tubules of the testes. The process is essential for the production of mature and functional sperm cells that are capable of fertilizing an egg.
The process of spermatogenesis can be divided into mitosis, meiosis, and spermiogenesis. During mitosis, the spermatogonia or stem cells divide to produce two identical daughter cells, type A and B spermatogonia. Type-A...

01:20Folliculogenesis
Folliculogenesis is the development of ovarian follicles, the specialized structures within the ovarian cortex where oogenesis, or egg development, occurs. This process is essential for female reproductive health and begins during fetal development when primordial follicles are formed. Each primordial follicle comprises a primary oocyte in the center, surrounded by a single layer of squamous pre-granulosa cells. These follicles remain dormant in late prophase I of meiosis until triggered by...
01:15Development of the Sexual Organs in the Embryo and Fetus
Development of the reproductive organs in an embryo starts from a bipotential state. This means the early embryo can develop either male or female reproductive organs. The formation of these organs begins with the growth of gonadal ridges that arise from the intermediate mesoderm during the fifth week of development.
Near the gonadal ridges, two duct systems are present: the mesonephric ducts (Wolffian ducts) and paramesonephric ducts (Müllerian ducts). These ducts form the basis for the male...
