  • 3 Embryology and Development
    BIOL 6505 − INTRODUCTION TO FETAL MEDICINE 3. EMBRYOLOGY AND DEVELOPMENT Arlet G. Kurkchubasche, M.D. INTRODUCTION Embryology – the field of study that pertains to the developing organism/human Basic embryology –usually taught in the chronologic sequence of events. These events are the basis for understanding the congenital anomalies that we encounter in the fetus, and help explain the relationships to other organ system concerns. Below is a synopsis of some of the critical steps in embryogenesis from the anatomic rather than molecular basis. These concepts will be more intuitive and evident in conjunction with diagrams and animated sequences. This text is a synopsis of material provided in Langman’s Medical Embryology, 9th ed. First week – ovulation to fertilization to implantation Fertilization restores 1) the diploid number of chromosomes, 2) determines the chromosomal sex and 3) initiates cleavage. Cleavage of the fertilized ovum results in mitotic divisions generating blastomeres that form a 16-cell morula. The dense morula develops a central cavity and now forms the blastocyst, which restructures into 2 components. The inner cell mass forms the embryoblast and outer cell mass the trophoblast. Consequences for fetal management: Variances in cleavage, i.e. splitting of the zygote at various stages/locations - leads to monozygotic twinning with various relationships of the fetal membranes. Cleavage at later weeks will lead to conjoined twinning. Second week: the week of twos – marked by bilaminar germ disc formation. Commences with blastocyst partially embedded in endometrial stroma Trophoblast forms – 1) cytotrophoblast – mitotic cells that coalesce to form 2) syncytiotrophoblast – erodes into maternal tissues, forms lacunae which are critical to development of the uteroplacental circulation.

  • The Genetic Basis of Mammalian Neurulation
    REVIEWS THE GENETIC BASIS OF MAMMALIAN NEURULATION Andrew J. Copp*, Nicholas D. E. Greene* and Jennifer N. Murdoch‡ More than 80 mutant mouse genes disrupt neurulation and allow an in-depth analysis of the underlying developmental mechanisms. Although many of the genetic mutants have been studied in only rudimentary detail, several molecular pathways can already be identified as crucial for normal neurulation. These include the planar cell-polarity pathway, which is required for the initiation of neural tube closure, and the sonic hedgehog signalling pathway that regulates neural plate bending. Mutant mice also offer an opportunity to unravel the mechanisms by which folic acid prevents neural tube defects, and to develop new therapies for folate-resistant defects. 6 ECTODERM Neurulation is a fundamental event of embryogenesis distinct locations in the brain and spinal cord .By The outer of the three that culminates in the formation of the neural tube, contrast, the mechanisms that underlie the forma- embryonic (germ) layers that which is the precursor of the brain and spinal cord.

  • Understanding Paraxial Mesoderm Development and Sclerotome Specification for Skeletal Repair Shoichiro Tani 1,2, Ung-Il Chung2,3, Shinsuke Ohba4 and Hironori Hojo2,3
    Tani et al. Experimental & Molecular Medicine (2020) 52:1166–1177 https://doi.org/10.1038/s12276-020-0482-1 Experimental & Molecular Medicine REVIEW ARTICLE Open Access Understanding paraxial mesoderm development and sclerotome specification for skeletal repair Shoichiro Tani 1,2, Ung-il Chung2,3, Shinsuke Ohba4 and Hironori Hojo2,3 Abstract Pluripotent stem cells (PSCs) are attractive regenerative therapy tools for skeletal tissues. However, a deep understanding of skeletal development is required in order to model this development with PSCs, and for the application of PSCs in clinical settings. Skeletal tissues originate from three types of cell populations: the paraxial mesoderm, lateral plate mesoderm, and neural crest. The paraxial mesoderm gives rise to the sclerotome mainly through somitogenesis. In this process, key developmental processes, including initiation of the segmentation clock, formation of the determination front, and the mesenchymal–epithelial transition, are sequentially coordinated. The sclerotome further forms vertebral columns and contributes to various other tissues, such as tendons, vessels (including the dorsal aorta), and even meninges. To understand the molecular mechanisms underlying these developmental processes, extensive studies have been conducted. These studies have demonstrated that a gradient of activities involving multiple signaling pathways specify the embryonic axis and induce cell-type-specific master transcription factors in a spatiotemporal manner. Moreover, applying the knowledge of mesoderm development, researchers have attempted to recapitulate the in vivo development processes in in vitro settings, using mouse and human PSCs. In this review, we summarize the state-of-the-art understanding of mesoderm development and in vitro modeling of mesoderm development using PSCs. We also discuss future perspectives on the use of PSCs to generate skeletal tissues for basic research and clinical applications.

  • THE HISTOGENESIS of BONE by C
    THE HISTOGENESIS OF BONE By C. WITHERINGTON STUMP, M.D. From the Laboratory of the Royal College of Physicians, Edinburgh INTRODUCTION FEW processes in histogenesis have been the subject of so much controversy, as that of the development of bone. On reading over the literature, even incompletely, the conviction came with considerable force, that the chief cause of the inability of observers, to find agreement, lay in technical difficulties in obtaining satisfactory preparations for cytological study. The divergent opinions are accounted for by the singular absence of detailed work-a fact which has fostered and sustained a controversy into which there is no need to enter. Microscopic evidence of cell growth and change is yielded by slight morpho- logical variations in different individual cells. Slight differences in structure, and staining reaction, are the only factors by means of which variations can be determined. It is essential, with cells examined in a dead state, to have a standard of fixation which registers detailed and minute structure. Further, it is constantly to be borne in mind, that merely a phase of life is represented, through which the cell was passing at the time of its death. Especially is this so in actively growing, developing tissue, where many structural tendencies are manifested by the act of growth. Thus, in fixed primitive tissue, the ontogeny of any given cell is a matter of conjecture, and it can only be defined with any degree of certainty by an experienced observer. It would be redundant to attempt an historical survey of the contributions to the problem of osteogenesis.

  • Labiatae) in South-Eastern Australia
    319 Contributions to the systematics of Prostanthera (Labiatae) in south-eastern Australia Barry J. Conn Abstract Conn, B.J. (Royal Botanic Gardens, Mrs Macquaries Road, Sydney NSW 2000, Australia) 1997. Contributions to the systematics of Prostanthera (Labiatae) in south-eastern Australia. Telopea 7(4): 319–332. Prostanthera cuneata is regarded as endemic to mainland Australia, with the type material based on cultivated material grown in Formosa garden, Tasmania. The new species Prostanthera galbraithiae B.J.Conn is here formally described. A morphological re-evaluation of Prostanthera melissifolia concludes that this species is endemic to Victoria. Prostanthera melissifolia sensu Conn, from the Northern Tablelands of New South Wales, is P. caerulea R.Br., and Prostanthera sp. aff. melissifolia sensu Beauglehole, from East Gippsland (Victoria), probably is P. incisa R.Br. (s. lat.). A full description, habitat notes, distribution map and illustration of each of the first three species are provided. Introduction This paper presents the conclusions of revisionary studies into the genus Prostanthera section Prostanthera, arising particularly from work towards the preparation of an account of the genus for the forthcoming Flora of Victoria, volume 4. Terminology follows Conn (1984), except inflorescence terminology as modified by Conn (1995). Distribution information for Victoria follows Conn (1993). 1. Distribution of Prostanthera cuneata Benth. Previously, Prostanthera cuneata has been regarded as occurring in New South Wales, Tasmania and Victoria. Although the type specimen of this species (Gunn 725, 7 Dec. 1842) is stated to have been collected from the ‘South Esk’ River, south of Launceston in Tasmania, Buchanan (1988, 1990) states that Gunn actually collected from ‘Formosa’ garden, on the estate of W.E.

  • Action Statement
    Action Statement Flora and Fauna Guarantee Act 1998 No. 2 31 Wellington Mint-bush Prosthanthera galbraithiae This Action Statement is based on a draft Recovery Plan prepared for this species by DSE under contract to the Australian Government Department of the Environment, Water, Heritage and the Arts. Description Wellington Mint-bush (Prostanthera galbraithiae ) is an erect or spreading shrub, 0.3–2 m tall (Walsh & Entwisle 1999). Young branches have a square- shaped cross-section, and are densely hairy between two faint lateral-running ridges and on nodes; the rest of the branch is hairless (Walsh & Entwisle 1999). The leaves are stalkless, arise in opposite pairs and have a slight aroma when crushed (Walsh & Entwisle 1999). They are linear, narrowly ovate or oblong, ~15 x 2 mm, mid green and mostly hairless (Walsh & Entwisle 1999). Flowers appear from September through to November, and are generally deep mauve to purple with deep mauve to purple spots in the throat. Distribution in Victoria The two upper petals form a hood and the three (Flora Information System DSE 2007) lower petals form a fan shape. The petals are 7 - 10 mm long; the middle petal of the lower three, however, is broader and longer than each of the two upper petals (Walsh & Entwisle 1999). The stamens have anthers which lack a basal appendage. The surrounding calyx is divided into two lips, the upper lip (curved backwards) grows to 5.5 mm in length. Eight to 24 flowers appear in a leafy, branched inflorescence that may be branched or unbranched. Distribution Abundance Wellington Mint-bush is restricted to the Holey It is estimated that over 1000 individuals exist in Plains State Park in the Gippsland Plains in Victoria 13 populations.
