adult leydig cells -

'Adult'-type Leydig cells differentiate in the post-natal testis and are quiescent until puberty. They are preceded in the testis by a population of 'fetal'-type Leydig cells from the 8th to the 20th week of gestation, which produce enough testosterone for masculinisation of a male fetus.

Adult Leydig cells originate within the testis postnatally. Their formation is a continuous process involving gradual transformation of progenitors into Cited by: 255.

Mar 08, 2016 · Testicular Leydig cells are the primary source of testosterone in males. Adult Leydig cells have been shown to arise from stem cells present in the neonatal testis. Once established, adult Leydig cells turn over only slowly during adult life, but when these cells are eliminated experimentally from the adult testis, new Leydig cells rapidly Cited by: 63. Apr 16, 2019 · Leydig cells play a pivotal function in the synthesis of a male sex steroid, testosterone. The ability of the steroid production is dependent on the expression of the steroidogenic genes, such as HSD3B (3β-hydroxysteroid dehydrogenase/Δ5- Δ4 isomerase). It has been established that two different types of Leydig cells, fetal Leydig cells (FLCs) and adult Leydig cells (ALCs), are developed in Cited by: 1.

Dec 01, 2018 · Previous studies have established that fetal Leydig cells (FLCs) and adult Leydig cells (ALCs) show distinct functional characteristics. However, the lineage relationship between FLCs and ALCs has not been clarified yet. Here, we reveal that a subset of FLCs dedifferentiate at fetal stages to give rise to ALCs at the pubertal stage. Moreover, the dedifferentiated cells contribute to the Cited by: 4. The EDS-treated regeneration of Leydig cells is a unique model for the investigation of the proliferation and differentiation of stem and progenitor Leydig cells in the adult-testis. Leydig cells in the adult-testis completely disappear after a rat is injected intraperitoneally a dose (75 mg/kg) of EDS (Teerds, 1996).Author: Yao Lv, Yinghui Fang, Panpan Chen, Yue Duan, Tongliang Huang, Leikai Ma, Lubin Xie, Xianwu Chen, Xia.
