In Vitro Proliferation of Adult Human Beta-Cells
A decrease in functional beta-cell mass is a key feature of type 2 diabetes. Glucagon-like peptide 1 (GLP-1) analogues induce proliferation of rodent beta-cells. However, the proliferative capacity of human beta-cells and its modulation by GLP-1 analogues remain to be fully investigated. We therefore sought to quantify adult human beta-cell proliferation in vitro and whether this is affected by...
متن کاملIn vitro proliferation of cells derived from adult human beta-cells revealed by cell-lineage tracing.
OBJECTIVE Expansion of insulin-producing beta-cells from adult human islets could alleviate donor shortage for cell-replacement therapy of diabetes. A major obstacle to development of effective expansion protocols is the rapid loss of beta-cell markers in the cultured cells. Here, we report a genetic cell-lineage tracing approach for following the fate of cultured beta-cells. RESEARCH DESIGN ...

متن کاملEffect of Ghrelin on Viability, Proliferation, and Apoptosis in Human Granulosa Cells, In Vitro
Background and Objectives: Ghrelin is a peptide hormone that was initially derived from stomach and introduced as an endogenous ligand for the growth hormone secretagogue receptor. Ghrelin is fundamentally involved in regulation of nutrition and energy homeostasis in the body. It has been shown that ghrelin has an important role in fertility in women. The purpose of the present study was to ass...
متن کاملculture and proliferation of human limbal stem cells in vitro
purpose: to evaluate the properties of cultured limbal stem cells for corneal surface reconstruction. methods: specimens of limbal explants were prepared from the eye bank of i.r. iran. the explants were cultured and expanded on acellular amniotic membrane for 21 days. the cultured cells were evaluated for expression of connexin 43 and keratinine k3 by immunocytochemistry and expression of k12 ...
