Question: Is non-neural tyrosine hydroxylase , via modulation of endocrine pancreatic precursors , required for normal development of beta cells in the mouse pancreas?
Answer: A non-neural catecholaminergic pathway appears to modulate the pancreatic endocrine precursor and insulin producing cell neogenesis. This finding may have important implications for approaches seeking to promote the generation of beta cells to treat diabetes.
yes
