2010年2月1日 · Spermatogenesis is a developmental process during which a small number of diploid spermatogonial stem cells produce a large number of highly differentiated spermatozoa …

2010年2月1日 · The present chapter will first deal with morphological aspects of male germ cell development, will then turn to gene expression patterns accompanying spermatogenesis, …

2019年8月1日 · Nutritional deficiency suppresses fish spermatogenesis by changing metabolic peptides that affect male reproduction. Metabolic hormones play essential regulatory roles in …

2009年5月1日 · We propose a nomenclature for fish germ cells to improve the comparability among different teleost fish but also to higher vertebrates. Survival and development of germ …

During spermatogenesis in all bony fishes, spermatogonia are associated in the germinal compartment with Sertoli cells by processes that join laterally. These processes completely …

In the following section, we will review fish spermatogonial cell morphology, distribution, identification, and niche, and the endocrine and paracrine regulation of spermatogenesis. In …

2010年2月1日 · In general, transcription of CYP17 and CYP19a genes was significantly up-regulated in both sexes, while vitellogenin (VTG) 1 gene was down- and up-regulated in …

Since FSH (besides luteinizing hormone, LH) stimulates steroidogenesis in fish, and since FSH is the only gonadotropin detected in the plasma of sexually immature salmonids, increased FSH …

Fish spermatogenesis, from spermatogonial stem-cell renewal to sperm maturation, is controlled by the sex steroid hormones. Mitotic divisions of spermatogonia can be categorized by …

2021年4月8日 · In this review, we discuss the general outline and expression pattern of the major genes involved in testicular development and gonadal steroidogenesis in fish.
