    Figure In chemical signaling, a cell may target itself (autocrine signaling), a cell connected by gap junctions, a nearby cell (paracrine signaling), or a distant cell (endocrine signaling). Paracrine signaling acts on nearby cells, endocrine signaling uses the circulatory system to transport ligands, and autocrine signaling acts on the signaling cell.

This project examined a publicly available dataset to quantify pathway dynamics during testicular development and spermatogenesis and anchor toxicant-perturbed pathways within the context of normal development. Genes significantly changed throughout testis development in mice were clustered by their direction of change using K-means Cited by: 3.

Abstract. Each major histologic category of testicular tumor includes hormonally functional neoplasms. Testicular germ cell tumors, sex cord-stromal tumors, and tumors of neuroendocrine origin are all capable of producing one or more hormones that may result in the clinical presentation of the tumor, be useful for diagnosis of the tumor, or serve as a tumor marker for guiding.

A complex milieu of hormones initiates diverse signaling pathways within and between cells of the testis to support the processes of steroidogenesis, spermatogenesis, and ultimately male fertility. This book covers the specification, regulation, and reprogramming of germ cell and germ line stem cells.

This book provides important information about the new insight into germ cell signaling and the genotoxic in vitro studies in testicular germ cells.

This book offers significant results about the origin, specification, and development of the female germ line in placental mammals and the germ cell tumors.

Description of the book "Bacterial Signaling": Providing a comprehensive insight into cellular signaling processes in bacteria, this is the first book to cover intercellular, transmembrane, as well as intra-cellular signaling and its relevance for biofilm formation, differentiation, host pathogen interactions, symbiotic relationships, chemotaxis and various stress responses.

Such stress conditions can cause changes in the dynamics of testicular microvascular blood flow, endocrine signaling, and germ cell apoptosis. Testicular oxidative stress appears to be a common feature in much of what underlies male infertility, which suggests that there may be benefits to developing better antioxidant therapies for relevant Cited by: Title: Nitric Oxide-cGMP Signaling: Its Role in Cell Junction Dynamics During Spermatogenesis VOLUME: 8 ISSUE: 1 Author(s):Dolores D.

Ann N Y Acad Sci. Dec; Proceedings of the XVIIIth North American Testis Workshop: Testicular Cell Dynamics and Endocrine Signaling, March 30. Such advances have resulted from efforts to integrate knowledge of (1) the signaling pathways and mechanisms that govern key steps in the differentiation and maturation of testicular cells, (2) the effects of toxicants on these processes, and (3) the common and species-specific features of normal and disordered testicular growth.

Both the testis and ovary are endocrine organs. Endocrine hormones from the pituitary (i.e., gonadotropins, follicle stimulating hormone (FSH), and luteinizing hor-mone (LH)) act on various cell types to influence cellular functions and cell – cell interactions. The influence these endocrine hormones have on cell – cell signaling events is.

The endocrine system broadcasts its hormonal messages to essentially all cells by secretion into blood and extracellular fluid. Like a radio broadcast, it requires a receiver to get the message - in the case of endocrine messages, cells must bear a receptor for the hormone being broadcast in order to respond.

The testes is the male reproductive organ held responsible for the production and storage of millions of tiny sperm cells. The testicles are oval-shaped and can grow to about five centimeters in length and 3 centimeters in diameter. The testes do indeed play a pivotal role in the endocrine system due its production of hormones, namely testosterone.

Cell signaling mechanisms Five major types of cell-cell signaling are considered (Figure ): 1. Endocrine cell signaling involves a signaling molecule, called a hormone, secreted by an endocrine cell and transported through the circulation to act on distant target cells.

An example is the steroid hormone testosterone producedFile Size: 1MB. The incidence of testicular germ cell tumors (TGCTs) has been increasing the past 4 to 6 decades; however, exposures that account for this rise have not been identified.

Marijuana use also grew during the same period, and it has been established that chronic marijuana use produces adverse effects on the human endocrine and reproductive by: and cryptorchidism have been demonstrated to increase testicular oxidative stress, which leads to an increase in germ cell apoptosis and subsequent hypospermatogenesis.

Such stress conditions can cause changes in the dynamics of testicular microvascular blood flow, endocrine signaling, and germ cell apoptosis.

This layer of connective tissue encompasses peritubular myoid cells, which are joined by punctate junctions to form a continuous sheet of cells. Connective tissue cells known as fibrocytes are typically seen on the interstitial surface of the tubular membrane.

Testicular growth in response to LH and FSH stimulation. Mean testicular volumes before initiation of the infusions were ± ml (vehicle), ± ml (48 h) and ± ml (96 h). Combined testicular weights in the three groups were ±± and ± g (vehicle, 48 and 96 h gonadotrophin, respectively).Cited by: 4.

Evidence supporting a role for estrogen in male reproductive tract development and function has been collected from rodents and humans.

Inhibin suppresses the effects of FSH locally in the testes as well as FSH secretion by the. In biology, cell signaling (cell signalling in British English) is part of any communication process that governs basic activities of cells and coordinates multiple-cell actions.

The ability of cells to perceive and correctly respond to their microenvironment is the basis of development, tissue repair, and immunity.

Insulin-like 3 (INSL3) plays a prominent role in male development and is supposed to induce the growth of the gubernaculum testis (g.t.), thus being directly involved in testicular descent in humans and rodents.

This happens through activation of the RXFP2 receptor (GREAT or LGR8). The INSL3-RXFP2 complex is reputed to play an additional paracrine role in the testis, possibly acting as part of Cited by: Endocrine (endo=inside crine=to secrete) - releases signal into bloodstream where it travels to other parts of the body.

Paracrine (para=side-by-side) - releases molecules locally, affects nearby cells Autocrine - self signaling neuroendocrine-neurons that release chemical signals (hormones).

The male gonad is the testis (pl, testes). The initial difference in male and female gonad development are dependent on testis-determining factor (TDF) the protein product of the Y chromosome SRY gene.

Recent studies have indicated that additional factors may also be required for full differentiation. The glands pdf secrete hormones comprise the endocrine system. The term hormone is sometimes extended to include chemicals produced by cells that affect the same cell (autocrine or intracrine signalling) or nearby cells (paracrine signalling).FMA:   Platelet-derived growth factor (PDGF)- A–deficient male mice were found to develop progressive reduction of testicular size, Leydig cells loss, and spermatogenic arrest.

In normal mice, the PDGF-A and PDGF-Rα expression pattern showed positive cells in the seminiferous epithelium and in interstitial mesenchymal cells, by: Endocrine disruptors (EDs) are chemical substances that affect physiological ebook in ebook body via hormonal regulation.
