With His Knack for Knowing What Stem Cells Want, Yoshiki Sasai Has Grown an Eye and Parts of a Brain in a Dish
THE BRAINMAKER BY DAVID CYRANOSKI With his knack for knowing what stem cells want, Yoshiki Sasai has grown an eye and parts of a brain in a dish. n December 2010, Robin Ali became suddenly coaxing neural stem cells to grow into elaborate structures. excited by the usually mundane task of reviewing As well as the optic cup1, he has cultivated the delicate tissue a scientific paper. “I was running around my room, layers of the cerebral cortex2 and a rudimentary, hormone- I waving the manuscript,” he recalls.

Acid Bath Offers Easy Path to Stem Cells
NEWS IN FOCUS that the pluripotent cells were converted mature cells and not pre-existing pluripotent cells. So she made pluripotent cells by stressing T cells, a type of white blood cell whose maturity is clear from a rearrangement that its genes undergo OBOKATA HARUKO during development. She also caught the con- version of T cells to pluripotent cells on video. Obokata called the phenomenon stimulus- triggered acquisition of pluripotency (STAP). The results could fuel a long-running debate. For years, various groups of scientists have reported finding pluripotent cells in the mam- malian body, such as the multipotent adult pro- genitor cells described4 by Catherine Verfaillie, a molecular biologist then at the University of Minnesota in Minneapolis. But others have had difficulty reproducing such findings. Obokata started the current project in the laboratory of tissue engineer Charles Vacanti at Harvard Uni- versity in Cambridge, Massachusetts, by looking at cells that Vacanti’s group thought to be pluri- potent cells isolated from the body5. But her A mouse embryo injected with cells made pluripotent through stress, tagged with a fluorescent protein. results suggested a different explanation: that pluripotent cells are created when the body’s REGENERATIVE MEDICINE cells endure physical stress. “The generation of these cells is essentially Mother Nature’s way of responding to injury,” says Vacanti, a co-author of the latest papers2,3.

Folliculo-Stellate Cells: Paracrine Communicators in the Anterior Pituitary John Morris* and Helen Christian*
The Open Neuroendocrinology Journal, 2011, 4, 77-89 77 Open Access Folliculo-stellate Cells: Paracrine Communicators in the Anterior Pituitary John Morris* and Helen Christian* Department of Physiology, Anatomy & Genetics, University of Oxford, South Parks Road, Oxford OX1 3QX, UK Abstract: Most research on the anterior pituitary (adenohypophysis) has concentrated on the endocrine cells characterized by their complement of cytoplasmic dense-cored vesicles containing the classic anterior pituitary hormones. However it has become increasingly clear over the last 20 years that cells first identified more than 50 years ago in the basis that they lack such dense-cored vesicles and now known generically as folliculo-stellate or follicular cells have important physiological functions and act as an adenohypophysis wide communication system. This brief review reveals the need for this communication system, what we know of the plethora of products secreted by Folliculo-Stellate cells, the many receptors to which they respond, and in particular, the role of these enigmatic cells in the physiology of the stress/immune axis, the gonadotroph cells and the pituitary vasculature. Finally we review the current evidence that cells in this category can act as stem cells in the adult pituitary. Keywords: Annexin 1, ABC-transporter, folliculo-stellate.

Lois 2008 iii CENTRAL RESPIRATORY CIRCUITS THAT CONTROL DIAPHRAGM FUNCTION IN CAT REVEALED BY TRANSNEURONAL TRACING James H. Lois, M. S. University of Pittsburgh, 2008 Previous transneuronal tracing studies in the rat and ferret have identified regions throughout the spinal cord, medulla, and pons that are synaptically linked to the diaphragm muscle; however, the extended circuits that innervate the diaphragm of the cat have not been well defined. The N2C strain of rabies virus has been shown to be an effective transneuronal retrograde tracer of the polysynaptic circuits innervating a single muscle. Rabies was injected throughout the left costal region of the diaphragm in the cat to identify brain regions throughout the neuraxis that influence diaphragm function. Infected neurons were localized throughout the cervical and thoracic spinal cord with a concentration of labeling in the vicinity of the phrenic nucleus where diaphragm motoneurons are known to reside. Infection was also found throughout the medulla and pons particularly around the regions of the dorsal and ventral respiratory groups and the medial and lateral reticular formations but also in several other areas including the caudal raphe nuclei, parabrachial nuclear complex, vestibular nuclei, ventral paratrigeminal area, lateral reticular nucleus, and retrotrapezoid nucleus. -

Basic Organization of Projections from the Oval and Fusiform Nuclei of the Bed Nuclei of the Stria Terminalis in Adult Rat Brain
THE JOURNAL OF COMPARATIVE NEUROLOGY 436:430–455 (2001) Basic Organization of Projections From the Oval and Fusiform Nuclei of the Bed Nuclei of the Stria Terminalis in Adult Rat Brain HONG-WEI DONG,1,2 GORICA D. PETROVICH,3 ALAN G. WATTS,1 AND LARRY W. SWANSON1* 1Neuroscience Program and Department of Biological Sciences, University of Southern California, Los Angeles, California 90089-2520 2Institute of Neuroscience, The Fourth Military Medical University, Xi’an, Shannxi 710032, China 3Department of Psychology, Johns Hopkins University, Baltimore, Maryland 21218 ABSTRACT The organization of axonal projections from the oval and fusiform nuclei of the bed nuclei of the stria terminalis (BST) was characterized with the Phaseolus vulgaris-leucoagglutinin (PHAL) anterograde tracing method in adult male rats. Within the BST, the oval nucleus (BSTov) projects very densely to the fusiform nucleus (BSTfu) and also innervates the caudal anterolateral area, anterodorsal area, rhomboid nucleus, and subcommissural zone. Outside the BST, its heaviest inputs are to the caudal substantia innominata and adjacent central amygdalar nucleus, retrorubral area, and lateral parabrachial nucleus. It generates moderate inputs to the caudal nucleus accumbens, parasubthalamic nucleus, and medial and ventrolateral divisions of the periaqueductal gray, and it sends a light input to the anterior parvicellular part of the hypothalamic paraventricular nucleus and nucleus of the solitary tract. The BSTfu displays a much more complex projection pattern. Within the BST, it densely innervates the anterodorsal area, dorsomedial nucleus, and caudal anterolateral area, and it moderately innervates the BSTov, subcommissural zone, and rhomboid nucleus. Outside the BST, the BSTfu provides dense inputs to the nucleus accumbens, caudal substantia innominata and central amygdalar nucleus, thalamic paraventricular nucleus, hypothalamic paraventricular and periventricular nuclei, hypothalamic dorsomedial nucleus, perifornical lateral hypothalamic area, and lateral tegmental nucleus. -

Central and Peripheral Peptides Regulating Eating
REVIEW Central and Peripheral Peptides Regulating Eating Behaviour and Energy Homeostasis in Anorexia Nervosa and Bulimia Nervosa: A Literature Review Alfonso Tortorella1, Francesca Brambilla2, Michele Fabrazzo1, Umberto Volpe1, Alessio Maria Monteleone1, Daniele Mastromo1 & Palmiero Monteleone1,3* 1Department of Psychiatry, University of Naples SUN, Napoli, Italy 2Department of Psychiatry, San Paolo Hospital, Milan, Italy 3Department of Medicine and Surgery, University of Salerno, Salerno, Italy Abstract A large body of literature suggests the occurrence of a dysregulation in both central and peripheral modulators of appetite in patients with anorexia nervosa (AN) and bulimia nervosa (BN), but at the moment, the state or trait-dependent nature of those changes is far from being clear. It has been proposed, although not definitively proved, that peptide alterations, even when secondary to malnutrition and/or to aberrant eating behaviours, might contribute to the genesis and the maintenance of some symptomatic aspects of AN and BN, thus affecting the course and the prognosis of these disorders. This review focuses on the most significant literature studies that explored the physiology of those central and peripheral peptides, which have prominent effects on eating behaviour, body weight and energy homeostasis in patients with AN and BN. The relevance of peptide dysfunctions for the pathophysiology of eating disorders is critically discussed. Copyright © 2014 John Wiley & Sons, Ltd and Eating Disorders Association.

Understanding Eating Disorders
Hormones and Behavior 50 (2006) 572–578 www.elsevier.com/locate/yhbeh Understanding eating disorders Per Södersten ⁎, Cecilia Bergh, Michel Zandian Karolinska Institutet, Section of Applied Neuroendocrinology, Center for Eating Disorders, AB Mando, Novum, S-141 57 Huddinge, Sweden Received 16 May 2006; revised 20 June 2006; accepted 21 June 2006 Available online 4 August 2006 Abstract The outcome in eating disorders remains poor and commonly used methods of treatment have little, if any effect. It is suggested that this situation has emerged because of the failure to realize that the symptoms of eating disorder patients are epiphenomena to starvation and the associated disordered eating. Humans have evolved to cope with the challenge of starvation and the neuroendocrine mechanisms that have been under this evolutionary pressure are anatomically versatile and show synaptic plasticity to allow for flexibility. Many of the neuroendocrine changes in starvation are responses to the externally imposed shortage of food and the associated neuroendocrine secretions facilitate behavioral adaptation as needed rather than make an individual merely eat more or less food. A parsimonious, neurobiologically realistic explanation why eating disorders develop and why they are maintained is offered. It is suggested that the brain mechanisms of reward are activated when food intake is reduced and that disordered eating behavior is subsequently maintained by conditioning to the situations in which the disordered eating behavior developed via the neural system for attention. In a method based on this framework, patients are taught how to eat normally, their physical activity is controlled and they are provided with external heat. The method has been proven effective in a randomized controlled trial. -
