Polysiphonia japonica Extract Attenuates Palmitate-Induced Toxicity and Enhances Insulin Secretion in Pancreatic Beta-Cells

Figure 2

Polysiphonia japonica extract (PJE) promotes insulin secretion in zebrafish. Zebrafish were incubated with 10 μg/mL PJE from 3 to 4 days postfertilization. (a) Heart rates of embryos were measured for 3 min. (b) Phase contrast images of zebrafish and fluorescence and confocal microscopy images of the β-cell mass of zebrafish. Scale bar: 200 μm. (c) Relative EGFP fluorescence levels from (b). (d) Number of β-cells per embryo from (b). –24. ; n.s.: no significance.
