TLDR
By systematically altering the germ cell contents of the hermaphrodite using mutant strains, this work has uncovered evidence of four cell-cell interactions that regulate maturation and ovulation in Caenorhabditis elegans.About:

Flk1-positive cells derived from embryonic stem cells serve as vascular progenitors
Jun K. Yamashita,Hiroshi Itoh,Masanori Hirashima,Minetaro Ogawa,Satomi Nishikawa,Takami Yurugi,Makoto Naito,Kazuwa Nakao,Shin-Ichi Nishikawa +8 more
TL;DR: It is shown that Flk1+ cells derived from embryonic stem cells can differentiate into both endothelial and mural cells and can reproduce the vascular organization process and offer potential for tissue engineering of the vascular system.

Receptor-mediated endocytosis in the Caenorhabditis elegans oocyte.
Barth D. Grant,David Hirsh +1 more
TL;DR: It is shown that the basic components and pathways of endocytosis trafficking are conserved between C. elegans and vertebrates, and that this system can be used to test the endocytic functions of any new gene.

Degradation of Paternal Mitochondria by Fertilization-Triggered Autophagy in C. elegans Embryos
Miyuki Sato,Ken Sato +1 more
TL;DR: It is shown that autophagy, which delivers cytosolic components to lysosomes for degradation, is required for the elimination of paternal mitochondria in Caenorhabditis elegans and thereby maternal inheritance of mitochondrial DNA.

A Sperm Cytoskeletal Protein That Signals Oocyte Meiotic Maturation and Ovulation
Michael A. Miller,Viet Q. Nguyen,Min-Ho Lee,Mary E. Kosinski,Tim Schedl,Richard M. Caprioli,David Greenstein +6 more
TL;DR: It is shown that the major sperm cytoskeletal protein (MSP) is a bipartite signal for oocyte maturation and sheath contraction, and MSP also functions in sperm locomotion, playing a role analogous to actin.
Journal ArticleDOI
AIR-2: An Aurora/Ipl1-related protein kinase associated with chromosomes and midbody microtubules is required for polar body extrusion and cytokinesis in Caenorhabditis elegans embryos.
TL;DR: The results suggest that during each meiotic and mitotic division, AIR-2 may coordinate the congression of metaphase chromosomes with the subsequent events of polar body extrusion and cytokinesis.

The structure of the nervous system of the nematode Caenorhabditis elegans
TL;DR: The structure and connectivity of the nervous system of the nematode Caenorhabditis elegans has been deduced from reconstructions of electron micrographs of serial sections as discussed by the authors.

Universal control mechanism regulating onset of M-phase
TL;DR: The onset of M-phase is regulated by a mechanism common to all eukaryotic cells and requires p34cdc2 dephosphorylation and association with cyclin.

Genetic Control of the Cell Division Cycle in Yeast
TL;DR: Two features which distinguish the cell cycle of Saccharomyces cerevisiae from most other eukaryotes are particularly useful for an analysis of the gene functions that control the cell division cycle.

Cytoplasmic control of nuclear behavior during meiotic maturation of frog oocytes.
Yoshio Masui,Clement L. Markert +1 more
TL;DR: Fully grown oocytes of the frog (Rana pipiens) undergo cytoplasmic and nuclear maturation when treated with progesterone after the follicular envelopes have been removed, and the arrest of mitosis and cleavage can be attributed to a specific “cytostatic factor” in the cy toplasm of the secondary oocyte.
