Does circulating bile salt-dependent lipase originate from the pancreas via intestinal transcytosis?
These in vivo data show that BSDL, normally present in blood, originates from exocrine pancreatic secretion and support the pathophysiologic relevance of BSDL transcytosis through the intestinal mucosa cell lining. Based on this, the implication of circulating BSDL in atherosclerosis merits careful attention.
Pressure-induced myocardial hypertrophy leads to upregulation of systemic EPCs, increased extra-cardiac angiogenesis, and upregulation of intra-myocardial bone marrow-derived endothelial and myocyte precursor cells. The data show that afterload-dependent regulation of bone marrow-derived progenitor cells contributes to angiogenesis in myocardial hypertrophy.
