Elimination of nurse cell nuclei that shuttle into oocytes during oogenesis.

J Cell Biol 2021 Jul 5;220(7). Epub 2021 May 5.

Cardiovascular Research Institute, University of California, San Francisco, San Francisco, CA.

Drosophila oocytes develop together with 15 sister germline nurse cells (NCs), which pass products to the oocyte through intercellular bridges. The NCs are completely eliminated during stages 12-14, but we discovered that at stage 10B, two specific NCs fuse with the oocyte and extrude their nuclei through a channel that opens in the anterior face of the oocyte. These nuclei extinguish in the ooplasm, leaving 2 enucleated and 13 nucleated NCs. Read More

Cellular and Supracellular Planar Polarity: A Multiscale Cue to Elongate the Egg Chamber.

Front Cell Dev Biol 2021 2;9:645235. Epub 2021 Mar 2.

Molecular, Cellular and Developmental Biology Department (MCD), Centre de Biologie Integrative (CBI), University of Toulouse, CNRS, UPS, Toulouse, France.

Tissue elongation is known to be controlled by oriented cell division, elongation, migration and rearrangement. While these cellular processes have been extensively studied, new emerging supracellular mechanisms driving tissue extension have recently been unveiled. Tissue rotation and actomyosin contractions have been shown to be key processes driving egg chamber elongation. Read More

Neuropeptide Y and maternal behavior in the female native Thai chicken.

Acta Histochem 2021 May 10;123(4):151698. Epub 2021 Mar 10.

School of Biology, Institute of Science, Suranaree University of Technology, Nakhon Ratchasima, Thailand. Electronic address:

Maternal care behaviors in birds include incubation and rearing behaviors. During incubating period, the hens stop laying and eating less due to food restriction as a natural fasting when compared with the rearing hens, resulting in low production of eggs and chicks. Neuropeptide Y (NPY), a neurotransmitter/neuromodulator, is very well known to be involved in food intake regulation in birds and mammals. Read More

DVM Student, Faculty of Veterinary Medicine, Islamic Azad University, Shoushtar Branch, Shoushtar, Iran.

All conjoined twins are originally born as a result of fertilizing one zygote (egg) and also called monozygotic twins experiencing an incomplete division of an embryo into two portions of the embryo usually causing the formation of the primary streak stage. The main reason for the creation of this defect is not obvious. Dead twin goat with one head, one trunk, four anterior limbs, and four posterior organs was referred to the Laboratory of the Faculty of Veterinary Medicine, Islamic Azad University, Shoushtar Branch, Shoushtar, Iran.

Department of Life Sciences, Imperial College London, Berkshire, United Kingdom; Natural History Museum, London, United Kingdom. Electronic address:

Amniotes, a clade of terrestrial vertebrates, which includes all of the descendants of the last common ancestor of the reptiles (including dinosaurs and birds) and mammals, is one of the most successful group of animals on our planet. In addition to having an egg equipped with an amnion, an adaptation to lay eggs on land, amniotes possess a number of other major morphological characteristics. Chief among them is the amniote skull, which can be classified into several major types distinguished by the presence and number of temporal fenestrae (windows) in the posterior part. Read More

A Progressive Somatic Cell Niche Regulates Germline Cyst Differentiation in the Drosophila Ovary.

Curr Biol 2021 Feb 18;31(4):840-852.e5. Epub 2020 Dec 18.

National Institute of Biological Sciences, No. 7 Science Park Road, Zhongguancun Life Science Park, Beijing 102206, China; Tsinghua Institute of Multidisciplinary Biomedical Research, Tsinghua University, Beijing 102206, China. Electronic address:

In the germarium of the Drosophila ovary, developing germline cysts are surrounded by a population of somatic escort cells that are known to function as the niche cells for germline differentiation; however, the underlying molecular mechanisms of this niche function remain poorly understood. Through single-cell gene expression profiling combined with genetic analyses, we here demonstrate that the escort cells can be spatially and functionally divided into two successive domains. The anterior escort cells (aECs) specifically produce ecdysone, which acts on the cystoblast to promote synchronous cell division, whereas the posterior escort cells (pECs) respond to ecdysone signaling and regulate soma-germline cell adhesion to promote the transition from 16-cell cyst-to-egg chamber formation.

Laboratoire de Biologie et de Modélisation de la Cellule, Univ Lyon, ENS de Lyon, UCB Lyon 1, CNRS, Lyon, France.

It is unknown how growth in one tissue impacts morphogenesis in a neighboring tissue. To address this, we used the Drosophila ovarian follicle, in which a cluster of 15 nurse cells and a posteriorly located oocyte are surrounded by a layer of epithelial cells. It is known that as the nurse cells grow, the overlying epithelial cells flatten in a wave that begins in the anterior. Read More

Human sperm chaperone HSPA2 distribution during in vitro capacitation.

J Reprod Immunol 2021 02 12;143:103246. Epub 2020 Nov 12.

Departamento de Biotecnología, Universidad de Alicante, Alicante, 03690, Spain; Cátedra Human Fertility, Universidad de Alicante, Alicante, Spain. Electronic address:

Human fertilization success depends on the ability of the spermatozoa to undergo capacitation. Even though this process can be conducted in vitro, the optimal time for a sperm cell to complete capacitation in vitro is still under discussion due to the lack of proper capacitation biomarkers. Here, we evaluated the influence of in vitro capacitation time on HSPA2 distribution over human sperm head testing this chaperone as a potential capacitation biomarker. Read More

Opposing JAK-STAT and Wnt signaling gradients define a stem cell domain by regulating differentiation at two borders.

Elife 2020 11 2;9. Epub 2020 Nov 2.

Department of Biological Sciences, Columbia University, New York, United States.

Many adult stem cell communities are maintained by population asymmetry, where stochastic behaviors of multiple individual cells collectively result in a balance between stem cell division and differentiation. We investigated how this is achieved for Follicle Stem Cells (FSCs) by spatially-restricted niche signals. FSCs produce transit-amplifying Follicle Cells (FCs) from their posterior face and quiescent Escort Cells (ECs) to their anterior. Read More

Numerous specimens belonging to the syllid genus Anguillosyllis Day were collected during several deep-sea studies conducted between 1970 and 2011 in depths ranging from 180 to nearly 5000 m. These quantitative studies demonstrated that members of this genus are not as uncommon as once thought but can be among the 10 most common infaunal species at some deep-sea locations. Study areas included Georges Bank (New England), the North, Mid, and South Atlantic Continental Slope and Rise (east coast of North America), the Gulf of Mexico (off Louisiana), off San Francisco, California, the Clarion-Clipperton Fracture Zone (Pacific Ocean), the South China Sea (off Brunei), the abyssal plain in the South Atlantic Ocean, and Antarctica (Scotia Sea, Weddell Sea).

GAGA Regulates Border Cell Migration in .

Int J Mol Sci 2020 Oct 10;21(20). Epub 2020 Oct 10.

Department of the Regulation of Genetic Processes, Institute of Molecular and Cellular Biology of the Siberian Branch of the Russian Academy of Sciences, 630090 Novosibirsk, Russia.

Collective cell migration is a complex process that happens during normal development of many multicellular organisms, as well as during oncological transformations. In oogenesis, a small set of follicle cells originally located at the anterior tip of each egg chamber become motile and migrate as a cluster through nurse cells toward the oocyte. These specialized cells are referred to as border cells (BCs) and provide a simple and convenient model system to study collective cell migration. Read More

Development 2020 11 15;147(22). Epub 2020 Nov 15.

Center for Computational and Integrative Biology, Rutgers, The State University of NJ, Camden, NJ 08102, USA

The Janus-kinase/signal transducer and activator of transcription (JAK/STAT) pathway regulates the anterior posterior axis of the follicle cells. In the anterior, it activates the bone morphogenetic protein (BMP) signaling pathway through expression of the BMP ligand (). In the posterior, JAK/STAT works with the epidermal growth factor receptor (EGFR) pathway to express the T-box transcription factor (). Read More
