sertoli cell
Definition
Noun: * Sertoli cell: An elongated, supportive cell found within the seminiferous tubules of the testis. Its primary function is to nourish, protect, and support developing sperm cells (spermatids) during the process of spermatogenesis. These cells form part of the blood-testis barrier.
Usage
Sertoli cells are a specific anatomical and physiological term used in biology and medicine. * It is typically used as a countable noun. * It is often discussed in the context of male reproductive biology, spermatogenesis, and endocrine function.
Examples
- The Sertoli cell provides structural and metabolic support to germ cells.
- Hormones like follicle-stimulating hormone (FSH) act directly on the Sertoli cells.
- Damage to the Sertoli cells can impair sperm production.
Advanced Usage
- Sertoli cell-only syndrome: A pathological condition of the testes characterized by the presence of Sertoli cells in the seminiferous tubules but a complete absence of germ cells, leading to infertility.
- Sertoli cell tumor: A rare type of testicular tumor that originates from these supportive cells.
Variants and Related Words
- Sustentacular cell: A more general histological term for a supporting cell; Sertoli cells are the sustentacular cells of the seminiferous tubules.
- Nurse cell: A descriptive term highlighting the nurturing function of the Sertoli cell.
Synonyms
- Sustentacular cell (of the testis)
- Nurse cell (in this specific context)
