Stem cells in the development and differentiation of the human adrenal glands.

abstract：:Ultra-thin frozen sections are ideal substrates for immunolabelling in high resolution electron microscopy. However, visualization of subcellular structures is inferior to that obtained with corresponding plastic sections. Although negative staining is generally effective and even superior to positive staining, the ac...

abstract：:The anatomical substrate for coordinated release from the dispersed gonadotropin-releasing hormone (GnRH) neuronal population remains obscure. There is physiological evidence that the GnRH hormone itself has a role in tonic inhibition or modulation of GnRH function. This has led to the hypothesis that there is an ultr...
