- Paraptosis-like cell death in Wistar rat granulosa cells

The follicular atresia is a normal process in mammals' ovaries. Along this process the non-selected oocytes to be ovulated are degraded. It has been described that during atresia, the apoptosis has been identified as the main route of elimination; however, some ultrastructural characteristics observed in the granulosa cells during the atretic process are not corresponding to the classical apoptotic process. In this work we have evidenced that those altered morphology is corresponding with the paraptosis process, which is characterized by the endoplasmic reticulum being swollen, no presence of active caspase-3, and the fragmented chromatin is absent.

We have compared two almost similar monolayer culture protocols and one rather different suspension culture approach for differentiation of NT2 cells into neuronal cells using efficiency, i.e. cell number, cluster number and size, as well as the expression of CNS specific markers (including GFAP and MAP2) as quantifiers. Based on the results of our comparative analysis, we have established a refined method for differentiation of NT2 cells in monolayer cultures. We visualize expression of neuronal proteins in NT2-N cells using monoclonal antibodies raised against the markers beta-III-tubulin and Synapsin I and validate the robustness of the method by quantifying cluster number in a dataset generated from multiple replicate experiments conducted during a period of 8 months.
- Mitochondrial trafficking through Rhot1 is involved in the aggregation of germinal granule components during primordial germ cell formation in Xenopus embryos
Haru Tada, Yuya Taira, Keisuke Morichika and Tsutomu Kinoshita
Version of Record online: 1 SEP 2016 | DOI: 10.1111/dgd.12310
Using Xenopus transgenic line with EGFP-labeled mitochondria and truncated form of mitochondria-anchor protein, we demonstrate that mitochondrial GTPase Rhot1 is essential for the aggregation of mitochondria and germinal granule components in germ plasm. Our results suggest that mitochondrial trafficking is involved in the aggregation of germinal granule components, which are essential for primordial germ cells formation.
- Molecular markers for X-ray-insensitive differentiated cells in the Inner and outer regions of the mesenchymal space in planarian Dugesia japonica (pages 609–619)
Machiko Teramoto, Tomomi Kudome-Takamatsu, Osamu Nishimura, Yang An, Makoto Kashima, Norito Shibata and Kiyokazu Agata

Planarian mesenchymal space can be divided into two regions using marker genes for both X-ray-sensitive cells and differentiated cells. These findings support the idea that the mesenchymal space may have a key role in regulation of the stem cell system in planarians.
- Human pancreatic islets develop through fusion of distinct β and α/δ islets
Version of Record online: 17 AUG 2016 | DOI: 10.1111/dgd.12308
Fetal pancreatic islets develop first in two distinct types consisting of β or α/δ cells, respectively. During the development, they fuse with each other forming the prototype of mature human islets.
