      NEUROG3 is a key regulator of pancreatic endocrine cell differentiation in mouse, essential for the generation of all mature hormone producing cells. It is repressed by Notch signaling that prevents pancreatic cell differentiation by maintaining precursors in an undifferentiated state. We show that, in zebrafish, neurog3 is not expressed in the pancreas Cited by:

Introduction: Clinical presentation of pancreas rejection through the evolution of surgical techniques and immunosuppressive therapies. Like other solid organs and tissues, pancreas allograft transplantation is generating several immunological responses in the recipient: the first one is rapid and includes humoral (antibody, complement) and cellular (natural killer cells, Author: Jean-Paul G.

Squifflet, Angelika C. Gruessner, Angelika C. Gruessner, Rainer W.G. Gruessner. Because of the different regeneration capabilities of the pancreas, the molecular mechanism of pancreatic regeneration is still not well understood. On the other hand, targeting the regeneration mechanism of pancreatic endocrine tissue in the form of islets, or β cells, can help control and even reverse diabetes mellitus [2], [3], [4].Author: Dilem Ceren Oran, Ipek Simay Gokulu, Seda Kizilel.

Islets of 1 d post-SZ mice contained 1–2 IN + cells. A and B, Islet of 1 d post-SZ/ mice examined by confocal microscopy.

The book details the-state-of-the-art in modern whole pancreas and islet transplantation, including donor selection, immunosuppression, complications, allograft pathology, and : In agreement with results from others, our data (Figures 5 and S5) indicate that Ngn3+ cells in adult pancreas islets are important for β-cell regeneration in mice.

On the other hand, the role of Ngn3 in human islet development and β-cell regeneration in adulthood remains poorly understood. The pancreas arises from a ventral and a dorsal bud, which fuse to form the definitive pancreas in the 6-week fetus. The gland, which is derived from the primitive duodenum, is.

The liver and the pancreas are target organs in which many researchers of bioartificial organs are interested (Prokop et al.

A study by the universities of Bergen, Norway, and Geneva, Switzerland, found that when beta cells - which make insulin - are wiped out in mice, surrounding cells step in and make the hormone.

Streptozotocin-induced diabetes can be reversed by hepatic oval cell activation through hepatic transdifferentiation and pancreatic islet by: Author summary Diseases resulting in retinal pigment epithelium (RPE) degeneration are among the leading causes of blindness worldwide, and no therapy exists that can replace RPE or restore lost vision.

One intriguing possibility is the development of therapies focused on stimulating endogenous RPE regeneration. For this to be possible, we must first gain a deeper Cited by: 3. The zebrafish has emerged as a powerful model for studying regeneration of the heart, spinal cord, liver, pancreas, retina, tail, and other tissues [2,3].

Among these regenerative structures, the adult zebrafish tail is unparalleled for its accessibility to amputation and relatively simple cellular organization [ 4 – 6 ].Cited by: Table 1: Cell renewal rates in different tissues of the human body.

Values are rounded to one significant digit. Giving context through daily life replacement processes, we note that hair elongates at about 1 cm per month (BNID ) while fingernails grow at about cm per month (BNID ), which is about the same speed as the continental spreading in plate.

Morphological organization of NIC in the mammalian pancreas. These structures consist of autonomic nerve cells, islet cells and nerve fibers in juxtaposition with each other, as described for the first time by Van Campenhout in studies on the histogenesis of islets in human, sheep and dog [].Later, Simard [] confirmed the presence of such complexes in the human pancreas at Cited by: 1.

The liver is an organ only found in vertebrates which detoxifies various metabolites, synthesizes proteins and produces biochemicals necessary for digestion and growth. In humans, it is located in the right upper quadrant of the abdomen, below the other roles in metabolism include the regulation of glycogen storage, decomposition of red blood cells and the Artery: Hepatic artery.

The pancreas of mammals shows large variations. The extremes are the unique, massive pancreas of humans, and the richly branched organ of the rabbit.

Usually, the main duct, the duct of Wirsung, opens into the duodenum very close to the hepatic duct. In humans, the pancreas weighs about oz (70 g). It can be divided into head, body, and tail. Resident tissue stem cells called satellite cells repair muscle after injury. However, how satellite cells operate inside living tissue is unclear.

Gurevich et al. exploited the optical clarity of zebrafish larvae and used a series of genetic approaches to study muscle injury. After injury, satellite cells divide asymmetrically to generate a progenitor pool for muscle replacement and Cited by: Neural tripeptide amide L-pyroglutamyl-L-histidyl-L-prolineamide (L-PHP, Thyrotropin-releasing hormone, TRH) is a fine molecular peptide that was first identified in the Central Nervous System (CNS) and discovered in many other regions of body later as a neuropeptide hormone or neuromodulator [].L-PHP stimulates the thyroid stimulating hormone (TSH) after it is released Cited by: 1.

The hypothalamus is a portion of the brain that contains a number of small nuclei with a variety of functions.

Cells for tissue engineering Carole A. Heath Recent advances in stem-cell technology have improved the prognosis for tissue engineering. The use of cultured stem and/or progenitor cells has the potential to improve the extent of regeneration, and also increases the likelihood that the transplant ed tissue will integrate with the surrounding tissue.

Adenosine regulates exocrine and endocrine secretions in the pancreas. Adenosine is considered to play a role in acini-to-duct signaling in the exocrine pancreas. To identify the molecular basis of functional adenosine receptors in the exocrine pancreas, immunohistochemical analysis was performed in the rat, mouse, and guinea pig pancreas, and the secretory rate and Cited by: 1.

Requirement of BMP signaling in the specification of the ventral pancreatic bud. Involvement of BMP signaling in liver bud specification was previously investigated with laf/alk8 mutants (Chung et al., ).In addition, Chung et al. () showed that VPB outgrowth was severely affected in alk8 mutants, and alk8 morphants have a hypoplasic ventral pancreas at 3 d postfertilization.

A method for complete pancreatectomy in the rabbit is described. The removal of the pancreas at one operation usually proved fatal, but a 3-stage operation with intervals of weeks between stages was satisfactory.

Larval lesion induces local regeneration of motor neurons.

Zebrafish larvae have been shown to be a useful model for studying regeneration of melanocytes (Yang et al., ; Yang and Johnson, ), hair cells (Harris et al., ), and fin, which was shown to regenerate by a mechanism similar to that at play during adult regeneration (Kawakami et al., a).

The book also features an extensive bibliography, and extensive bodies of independent data on organ regeneration from the journal literature. In short, the generic organ-blind methodology described in this volume should be useful to most students and practitioners of tissue engineering.

Obesity is a major cause of type 2 diabetes mellitus (T2DM) in mammals. We have previously established a zebrafish model of diet-induced obesity (DIO zebrafish) by. A set of trans-organ rules is established and its use in regeneration of several organs is illustrated from the works of several independent investigators who worked with a variety of organs, such as the lung, the bladder, and the Achilles tendon, using collagen-based scaffolds somewhat similar to the original one.

The pancreas was removed within thirty minutes of death. From this clinical history one might expect the pancreas to show marked degeneration. However, on section there was little sign of degeneration, but on the other hand there was strong evidence to support the view of active regeneration both of acinar and islet tissue.
