distal cauda epididymidis rat
<
2009/2/23
The transport of [3H]myo-inositol into the lumen of the rat distal cauda epididymidis was studied by luminal perfusion in vitro. Entry was time and tubule length-dependent and saturable transport ...
Radioautographic localization of atrial natriuretic factor receptors in the rat testis
Radioautographic localization atrial natriuretic factor receptors rat testis
<
2009/2/23
Recent data have suggested that atrial natriuretic factors (ANFs) can modulate Leydig cell functions. An in vitro radioautographic procedure on slide-mounted frozen testicular sections was used to l...
The regulation of the proliferation and differentiation of rat Leydig cell precursor cells after EDS administration or daily HCG treatment
Leydig cell Leydig cell precursor LH hCG EDS proliferation
