The clinical and biochemical abnormalities expressed in the mice resemble Niemann-Pick type C and D disorders in humans. One of the proposed mechanisms to explain the pathophysiology of the disorder implies a defect in the process of membrane transport that normally takes place in the vesicular movement of cholesterol to specific target sites in the cell.<\/jats:p>\n               <jats:p>Secretory granule formation in pancreatic acinar cells is one of the biological processes known to involve massive membrane flow. Thus, we have undertaken a morphometric study of the regranulation mechanism in the pancreatic acinar cells of the mutant mice, as a way of studying cellular membrane movement.<\/jats:p>\n               <jats:p>Electron micrographs of pancreatic acinar cells from mutant and normal mice were taken at several time points after extensive degranulation induced by pilocarpine injection. Two hours after stimulation the pancreatic cells demonstrated a complete loss of granules, and at later time points newly formed granules appeared. Identical unit granule volumes were observed in both groups, indicating that the progranules were of normal size. However, the rate of granule formation and maturation was reduced in the mutant mice, which might be the result of a defect in membrane function.<\/jats:p>","DOI":"10.1242\/jcs.102.1.141","type":"journal-article","created":{"date-parts":[[2021,4,25]],"date-time":"2021-04-25T15:21:02Z","timestamp":1619364062000},"page":"141-147","source":"Crossref","is-referenced-by-count":13,"title":["Morphometric studies of pancreatic acinar granule formation in NCTR-Balb\/c mice"],"prefix":"10.1242","volume":"102","author":[{"given":"H.","family":"Weintraub","sequence":"first","affiliation":[{"name":"Tel-Aviv University 1 Department of Pathology, Sackler School of Medicine , , Ramat-Aviv, Tel-Aviv, Israel 69978"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.","family":"Abramovici","sequence":"additional","affiliation":[{"name":"Tel-Aviv University 1 Department of Pathology, Sackler School of Medicine , , Ramat-Aviv, Tel-Aviv, Israel 69978"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D.","family":"Amichai","sequence":"additional","affiliation":[{"name":"Tel-Aviv University 1 Department of Pathology, Sackler School of Medicine , , Ramat-Aviv, Tel-Aviv, Israel 69978"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"T.","family":"Eldar","sequence":"additional","affiliation":[{"name":"Tel-Aviv University 1 Department of Pathology, Sackler School of Medicine , , Ramat-Aviv, Tel-Aviv, Israel 69978"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"L.","family":"Ben-Dor","sequence":"additional","affiliation":[{"name":"Tel-Aviv University 1 Department of Pathology, Sackler School of Medicine , , Ramat-Aviv, Tel-Aviv, Israel 69978"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"P.
