Vom Fachbereich Biologie der Philipps-Universitat¨ Marburg (Hochschul- kennziffer 1180) als Dissertation angenommen am Erstgutachter*in: Prof. Dr. Monika Hassel Zweitgutachter*in: Prof. Dr. Christian Helker Tag der Disputation: Abstract Fibroblast growth factor receptor (FGFR) signaling is crucial in animal development. Two FGFRs and one FGFR-like receptor, which lacks the intracellular domain, are known in the Cnidarian Hydra vulgaris. FGFRa, also known as Kringelchen, is an important factor in the developmental process of budding, as it controls the detachment of the bud. It is still unknown, which extracellular ligands are responsible for the start of the relevant signal transduction cascades in Hydra. This study gives first insights into the potential functions of five FGFs previously identified in Hydra. Analysis of the gene and protein expression patterns of different FGFs in several Hydra strains suggest that FGFs may comprise evolutionary conserved, multiple functions in bud detachment, neurogenesis, migration and cell differentiation, as well as in the regeneration of head and foot structures in Hydra. The electroporation of siRNAs into adult Hydra was used to analyze knockdown effects of FGFs and FGFRs in Hydra. This method was efficiently reproducing phenotypes obtained using the FGFR inhibitor SU5402 or, alternatively phosphorothioate antisense oligonucleotides or a dominant-negative FGFR mutant.

  • DEVELOPMENTAL BIOLOGY LECTURE NOTES Regeneration If
    DEVELOPMENTAL BIOLOGY LECTURE NOTES Regeneration If the tail of a house lizard is cut, the missing part develops again from the remaining part of the tail. In some cases, regeneration is so advanced that an entire multicellular body is reconstructed from a small fragment of tissue. Our body spontaneously loses cells from the surface of the skin and replaced by newly formed cells. This is due to regeneration. Regeneration can be defined as the natural ability of living organisms to replace worn out parts, repair or renew damaged or lost parts of the body, or to reconstitute the whole body from a small fragment during the post embryonic life of an organism. Regeneration is thus also a developmental process that involves growth, morphogenesis and differentiation. Types of Regeneration Physiological Regeneration There is a constant loss of many kinds of cells due to wear and tear caused by day-to-day activities. The replacement of these cells is known as physiological regeneration Example: Replacement of R.B.C's The worn out R.B.C's are deposited in the spleen and new R.B.C's regularly produced from the bone marrow cells, since the life span of R.B.C's is only 120days. Replacement of Epidermal Cells of the Skin The cells from the outer layers of epidermis are regularly peeled off by wear and tear. These are constantly being replaced by new cells added by the malpighian layer of the skin. Reparative Regeneration This is the replacement of lost parts or repair of damaged body organs. In this type of regeneration, wound is repaired or closed by the expansion of the adjoining epidermis over the wound.

This type of organ regeneration, in which a mass of undifferentiated cells referred to as the “blastema” proliferate to restore the lost part of the amputated organ, is distinct from morphallaxis as observed, for instance, in Hydra, in which rearrangement of pre-existing cells and tissues mainly contribute to regeneration. In contrast to complete limb regeneration in urodele amphibians, limb regeneration in Xenopus, an anuran amphibian, is restricted. In this review of some aspects regarding adult limb regeneration in Xenopus laevis, we suggest that limb regeneration in adult Xenopus, which is pattern/tissue deficient, also represents epimorphosis. KEYWORDS: Xenopus, epimorphosis, limb regeneration, dedifferentiation, blastema, spike, nerve dependence, muscle regeneration, wound healing PROCESS OF LIMB REGENERATION IN VERTEBRATES Regenerative ability of appendages (limbs/fins) in vertebrates varies greatly[1]. Teleost fishes are capable of regenerating radial rays of their pectoral and pelvic fins as well as caudal fins, but they cannot regenerate internal skeletal elements at the base of their fins[2,3]. Birds such as chickens cannot regenerate even limb buds at any stage of development, though the implantation of additional AER (apical ectodermal ridge)- or FGF-soaked beads partially rescues the limb structure of amputated limb buds[4,5,6].

  • Regeneration of Limb in Salamander
    Regeneration of limb in salamander By Kartik Samanta Regeneration Regeneration is the reactivation of developmental processes in post- embryonic life to restore missing tissues/organs. Types of regeneration Regeneration does in fact take place in all species and can occur in four major ways: STEM CELL REGENERATION: Stem cells allow an organism to regrow certain organs or tissues that have been lost. Examples include the regrowth of hair shafts from follicular stem cells in the hair bulge and the continual replacement of blood cells from the hematopoietic stem cells in bone marrow. EPIMORPHOSIS: Here, adult structures can undergo dedifferentiation to form relatively undifferentiated mass of cells that the redifferentiates to form the new structure. Such epimorphosis is characteristic of planarian flatworm regeneration and also of regenerating amphibian limbs. MORPHALLAXIS: Here, regeneration occurs through the repatterning of existing tissues and there is little new growth. Such regeneration is seen in Hydra. COMPENSATORY REGENERATION: Here, the differentiated cells divide but maintain their differentiated functions. The new cells do not come from stem cells, nor they come from the dedifferentiation of the adult cells. Each cell produces cells similar to itself, no mass of undifferentiated tissue forms. This type of regeneration is characteristic of the mammalian liver. Regeneration blastema When an adult salamander limb is amputated, the remaining limb cells are able to reconstruct a complete new limb, with its all differentiated cells arranged in the proper order. In other words, the new cells construct only the missing structures and no more. For example, when a wrist is amputated, the salamander forms a new wrist and a new elbow.

  • Regeneration Versus Scarring in Vertebrate Appendages and Heart
    Journal of Pathology J Pathol 2015 INVITED REVIEW Published online in Wiley Online Library (wileyonlinelibrary.com) DOI: 10.1002/path.4644 Regeneration versus scarring in vertebrate appendages and heart Anna Jazwi´ nska´ * and Pauline Sallin Department of Biology, University of Fribourg, Switzerland *Correspondence to: A Jazwi´ nska,´ Department of Biology, University of Fribourg, Chemin du Musée 10, 1700 Fribourg, Switzerland. E-mail: [email protected] Abstract Injuries to complex human organs, such as the limbs and the heart, result in pathological conditions, for which we often lack adequate treatments. While modern regenerative approaches are based on the transplantation of stem cell-derived cells, natural regeneration in lower vertebrates, such as zebrafish and newts, relies predominantly on the intrinsic plasticity of mature tissues. This property involves local activation of the remaining material at the site of injury to promote cell division, cell migration and complete reproduction of the missing structure. It remains an unresolved question why adult mammals are not equally competent to reactivate morphogenetic programmes. Although organ regeneration depends strongly on the proliferative properties of cells in the injured tissue, it is apparent that various organismic factors, such as innervation, vascularization, hormones, metabolism and the immune system, can affect this process. Here, we focus on a correlation between the regenerative capacity and cellular specialization in the context of functional demands, as illustrated by appendages and heart in diverse vertebrates. Elucidation of the differences between homologous regenerative and non-regenerative tissues from various animal models is essential for understanding the applicability of lessons learned from the study of regenerative biology to clinical strategies for the treatment of injured human organs.

  • The Role of Fibroblast Growth Factor Signalling in Epimorphic Regeneration
    THE ROLE OF FIBROBLAST GROWTH FACTOR SIGNALLING IN EPIMORPHIC REGENERATION (Synopsis of thesis) Isha Ranadive DEPARTMENT OF ZOOLOGY, FACULTY OF SCIENCE, THE MAHARAJA SAYAJIRAO UNIVERSITY OF BARODA, VADODARA- 390002, INDIA INTRODUCTION Regeneration in an adult animal is a striking example of post-embryonic morphogenesis. It involves the recognition of tissue loss or injury, followed by mechanisms that reconstruct or restore the relevant structure (Brockes, 2001). There are three primary ways by which regeneration can occur. The first mechanism involves the dedifferentiation of adult structures to form an undifferentiated mass of cells that then becomes respecified. This type of regeneration is called epimorphosis and is characteristic of regenerating limbs. The second mechanism is called morphallaxis. Here, regeneration occurs through the re-patterning of existing tissues, and there is little new growth. Such regeneration is seen in hydras. The third type of regeneration is an intermediate type and can be thought of as compensatory regeneration. Here, the cells divide but maintain their differentiated functions. They produce cells similar to themselves and do not form a mass of undifferentiated tissue. This type of regeneration is characteristic of the mammalian liver (Gilbert 2014). A diagrammatic representation of these three types of regeneration has been portrayed in figure 1. Figure 1: Types of regeneration Isha Ranadive (Synopsis of Thesis) 1 The ability of adult animals to regenerate large sections of the primary or secondary body axes is not found in all phyla. Six phyla, including rotifers and nematodes, are considered to exhibit cell constancy after embryological development (Hughes, 1989; S´anchez Alvarado, 2000). Out of these, our lab has been working on class reptilian wherein the model organism is Hemidactylus flaviviridis and class Pisces wherein the model organism is Poecilia latipinna.

  • Lecture on Regeneration
    Buddhi Prakash Jain Assistant Professor Department of Zoology Mahatma Gandhi Central University Motihari Objectives of the lecture: 1. Concept of the regeneration. 2. Mode of regeneration. 3. Mechanism of salamander limb regeneration. 1. Concept of the regeneration Dear students you might have seen a house lizard without tail. After some days the tail develops again from the remaining part. This process of development of missing part or structure is due to regeneration. Our body also lose some of the cells and replaced by new ones. It is post embryonic developmental process. “Regeneration can be defined as the ability of living organisms to replace damaged or lost parts of the body or to reconstitute the whole organism from small fragments of the body”. Regeneration is carried out by specialized cells called stem cells. Regeneration was first reported in Hydra by Tremble in 1740. T.H. Morgan studied regeneration in Planaria. Limb and tail regeneration in Salamanders was described by Spallanzani. The regenerative capacity is present in different animal kingdom but with varying degree. In lower animal kingdom as sponge, coelenterate, flat worm the regenerative capacity is very high. In higher kingdom the regeneration is higher in embryonic and larval stage. In adult stage it is restricted to certain parts or organs. 2. Mode of regeneration There are three major ways (types) of regeneration: 1. Epimorphosis: Regeneration of some lost or damaged part. This type of regeneration occurs by proliferation of new cells from the surface of the injured part. In this type of regeneration, first the adult structure at the lost or damaged part dedifferentiate, and then proliferate to increase the number of dedifferentiated cells and form blastema.
