Leydig cells express neural cell adhesion molecules in vivo and in vitro [PDF]

open access: yes, 1992
The neural cell adhesion molecule (NCAM) polypeptides are expressed by numerous tissues during embryonic development, where they are involved in cell-cell interactions.

Regulation of development of rat stem and progenitor Leydig cells by activin [PDF]

open access: yesAndrology, 2016
SummaryStem Leydig cells have been demonstrated to differentiate into adult Leydig cells via intermediate stages of progenitor and immature Leydig cells. However, the exact regulatory mechanisms are unclear. We hypothesized that the development of stem or progenitor Leydig cells depends upon locally produced growth factors. Microarray analysis revealed

Persistent Wnt/β-catenin signaling determines dorsalization of the postnatal subventricular zone and neural Stem cell specification into oligodendrocytes and glutamatergic neurons [PDF]

open access: yes, 2014
In the postnatal and adult central nervous system (CNS), the subventricular zone (SVZ) of the forebrain is the main source of neural stem cells (NSCs) that generate olfactory neurons and oligodendrocytes (OLs), the myelinating cells of the CNS.

Transcriptional Profiling of Luteinizing Hormone Receptor-Deficient Mice Before and after Testosterone Treatment Provides Insight into the Hormonal Control of Postnatal Testicular Development and Leydig Cell Differentiation [PDF]

open access: yes, 2010
Luteinizing hormone (LH) is a key regulator of male fertility through its effects on testosterone secretion by Leydig cells. Transcriptional control of this is, however, currently poorly understood.

Effects of spermatogenic cycle on Stem Leydig cell proliferation and differentiation [PDF]

open access: yesMolecular and Cellular Endocrinology, 2019
We reported previously that stem Leydig cells (SLC) on the surfaces of rat testicular seminiferous tubules are able to differentiate into Leydig cells. The proliferation and differentiation of SLCs seem likely to be regulated by niche cells, including nearby germ and Sertoli cells. Due to the cyclical nature of spermatogenesis, we hypothesized that the

Slow Turning Lateral Vessel Bioreactor Improves Embryoid Body Formation and Cardiogenic Differentiation of Mouse Embryonic Stem Cells. [PDF]

open access: yes, 2013
Embryonic stem cells (ESCs) have the ability to form aggregates, which are called embryoid bodies (EBs). EBs mimic early embryonic development and are commonly produced for cardiomyogenesis.

Notch promotes neural lineage entry by pluripotent embryonic stem cells [PDF]

open access: yes, 2006
A central challenge in embryonic stem (ES) cell biology is to understand how to impose direction on primary lineage commitment. In basal culture conditions, the majority of ES cells convert asynchronously into neural cells.

GENERATION OF MOUSE INDUCED PLURIPOTENT STEM CELLS BY PROTEIN TRANSDUCTION. [PDF]

open access: yes, 2013
Somatic cell reprogramming has generated enormous interest after the first report by Yamanaka and his coworkers in 2006 on the generation of induced pluripotent stem cells (iPSCs) from mouse fibroblasts. Here we report the generation of stable iPSCs from

CCL2 enhances pluripotency of human induced pluripotent stem cells by activating hypoxia related genes [PDF]

open access: yes, 2014
Standard culture of human induced pluripotent stem cells (hiPSCs) requires basic Fibroblast Growth Factor (bFGF) to maintain the pluripotent state, whereas hiPSC more closely resemble epiblast stem cells than true naïve state ES which requires LIF to ...
