Synthesis and Functionalization of Nitrogen-doped Carbon Nanotube Cups with Gold Nanoparticles as Cork Stoppers

¹Department of Chemistry, University of Pittsburgh

We discussed the synthesis of individual graphitic nanocups using a series of techniques including chemical vapor deposition, acid oxidation and probe-tip sonication. By citrate reduction of HAuCl₄, the graphitic nanocups were effectively corked with gold nanoparticles due to the chemically reactive edges of the cups.

Here we present an adaptation of the passive CLARITY and 3D reconstruction method for visualization of the ovarian vasculature and follicular capillaries in intact mouse ovaries.

Exosome application is an emerging tool for drug development and regenerative medicine. We establish an exosome isolation protocol with high purity to isolate exosomes from novel identified stem cells called CB-SC for mechanistic studies. We also coculture CB-SC-derived exosomes with human monocytes, leading to their differentiation into phenotypically distinct macrophages.

Separation of Follicular Cells and Oocytes in Ovarian Follicles of Zebrafish

Wenyi Wang¹, Tao Kang¹, Lin Bai¹, Wei Hu², Yayoi Obata³, Jianzhen Li¹

¹College of Life Sciences, Northwest Normal University, ²State Key Laboratory of Freshwater Ecology and Biotechnology, Institute of Hydrobiology, Chinese Academy of Sciences, ³Department of Bioscience, Tokyo University of Agriculture

Here, we present a simple method for separating follicular cells and oocytes in zebrafish ovarian follicles, which will facilitate investigations of ovarian development in zebrafish.
