Ultrastructural alterations of the pancreatic D cell in the domestic fowl following vagotomy.

abstract：:Mesenchymal stem cells (MSCs) are increasingly being reported as occurring in a variety of tissues. Although MSCs from human bone marrow are relatively easy to harvest, the isolation of rodent MSCs is more difficult, thereby limiting the number of experiments in vivo. To determine a suitable cell source, we isolated r...
