Proliferating and migrating effects of regenerating sea anemone Aulactinia stella cells-derived exosomes on human skin fibroblasts. Nat Prod Res 2024:1-8. [PMID: 38824422 DOI: 10.1080/14786419.2024.2352144] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2024] [Accepted: 05/01/2024] [Indexed: 06/03/2024]
Abstract
Regenerative effects of sea anemone-derived exosomes on human foreskin fibroblasts (HFFs) were investigated. Water-based extracts from regenerating Aulactinia stella tissue were collected at various time points, and exosomes were extracted after inducing wounds. Both the extract and exosomes were tested on HFF for proliferation and in vitro wound healing. In silico analysis explored protein-protein docking between regenerative exosome proteins and HFF receptors. The MTT (3-(4,5-dimethylthiazol-2yl)-2,5 diphenyltetrazolium bromide proliferation assay and in vitro wound healing test of aquatic extract showed proliferative effects on HFF cell lines, with the 60 μg/mL concentration significantly enhancing cell migration. Exosomes were characterised. Exosomes showed a significantly positive effect on cell proliferation and migration at the 50 µg/mL concentration 48 h post-wound induction. In silico analysis revealed potential binding affinities between exosome proteins and HFF receptors. In conclusion, optimised concentrations of A. stella-derived exosomes exhibited positive effects on HFF regeneration and migration, suggesting their potential in accelerating wound healing.

Abstract
Reproductive propagation by asexual fragmentation in the reef-building coral Acropora millepora depends on (1) successful attachment to the reef substrate through modification of soft tissues and (2) a permanent bond with skeletal encrustation. Despite decades of research examining asexual propagation in corals, the initial response, cellular reorganisation, and development leading to fragment substrate attachment via a newly formed skeleton has not been documented in its entirety. Here, we establish the first "coral attachment model" for this species ("Am-CAM") by developing novel methods that allow correlation of fluorescence and electron microscopy image data with in vivo microscopic time-lapse imagery. This multi-scale imaging approach identified three distinct phases involved in asexual propagation: (1) the contact response of the coral fragment when contact with the substrate, followed by (2) fragment stabilisation through anchoring by the soft tissue, and (3) formation of a "lappet-like appendage" structure leading to substrate bonding of the tissue for encrustation through the onset of skeletal calcification. In developing Am-CAM, we provide new biological insights that can enable reef researchers, managers and coral restoration practitioners to begin evaluating attachment effectiveness, which is needed to optimise species-substrate compatibility and achieve effective outplanting.

Presnell JS, Wirsching E, Weis VM. Tentacle patterning during Exaiptasia diaphana pedal lacerate development differs between symbiotic and aposymbiotic animals. PeerJ 2022; 10:e12770. [PMID: 35047238 PMCID: PMC8757374 DOI: 10.7717/peerj.12770] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2021] [Accepted: 12/19/2021] [Indexed: 01/07/2023] Open
Abstract
Exaiptasia diaphana, a tropical sea anemone known as Aiptasia, is a tractable model system for studying the cellular, physiological, and ecological characteristics of cnidarian-dinoflagellate symbiosis. Aiptasia is widely used as a proxy for coral-algal symbiosis, since both Aiptasia and corals form a symbiosis with members of the family Symbiodiniaceae. Laboratory strains of Aiptasia can be maintained in both the symbiotic (Sym) and aposymbiotic (Apo, without algae) states. Apo Aiptasia allow for the study of the influence of symbiosis on different biological processes and how different environmental conditions impact symbiosis. A key feature of Aiptasia is the ease of propagating both Sym and Apo individuals in the laboratory through a process called pedal laceration. In this form of asexual reproduction, small pieces of tissue rip away from the pedal disc of a polyp, then these lacerates eventually develop tentacles and grow into new polyps. While pedal laceration has been described in the past, details of how tentacles are formed or how symbiotic and nutritional state influence this process are lacking. Here we describe the stages of development in both Sym and Apo pedal lacerates. Our results show that Apo lacerates develop tentacles earlier than Sym lacerates, while over the course of 20 days, Sym lacerates end up with a greater number of tentacles. We describe both tentacle and mesentery patterning during lacerate development and show that they form through a single pattern in early stages regardless of symbiotic state. In later stages of development, Apo lacerate tentacles and mesenteries progress through a single pattern, while variable patterns were observed in Sym lacerates. We discuss how Aiptasia lacerate mesentery and tentacle patterning differs from oral disc regeneration and how these patterning events compare to postembryonic development in Nematostella vectensis, another widely-used sea anemone model. In addition, we demonstrate that Apo lacerates supplemented with a putative nutrient source developed an intermediate number of tentacles between un-fed Apo and Sym lacerates. Based on these observations, we hypothesize that pedal lacerates progress through two different, putatively nutrient-dependent phases of development. In the early phase, the lacerate, regardless of symbiotic state, preferentially uses or relies on nutrients carried over from the adult polyp. These resources are sufficient for lacerates to develop into a functional polyp. In the late phase of development, continued growth and tentacle formation is supported by nutrients obtained from either symbionts and/or the environment through heterotrophic feeding. Finally, we advocate for the implementation of pedal lacerates as an additional resource in the Aiptasia model system toolkit for studies of cnidarian-dinoflagellate symbiosis.

Nematostella vectensis, an Emerging Model for Deciphering the Molecular and Cellular Mechanisms Underlying Whole-Body Regeneration. Cells 2021; 10:cells10102692. [PMID: 34685672 PMCID: PMC8534814 DOI: 10.3390/cells10102692] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2021] [Revised: 09/30/2021] [Accepted: 10/04/2021] [Indexed: 12/18/2022] Open
Abstract
The capacity to regenerate lost or injured body parts is a widespread feature within metazoans and has intrigued scientists for centuries. One of the most extreme types of regeneration is the so-called whole body regenerative capacity, which enables regeneration of fully functional organisms from isolated body parts. While not exclusive to this habitat, whole body regeneration is widespread in aquatic/marine invertebrates. Over the past decade, new whole-body research models have emerged that complement the historical models Hydra and planarians. Among these, the sea anemone Nematostella vectensis has attracted increasing interest in regard to deciphering the cellular and molecular mechanisms underlying the whole-body regeneration process. This manuscript will present an overview of the biological features of this anthozoan cnidarian as well as the available tools and resources that have been developed by the scientific community studying Nematostella. I will further review our current understanding of the cellular and molecular mechanisms underlying whole-body regeneration in this marine organism, with emphasis on how comparing embryonic development and regeneration in the same organism provides insight into regeneration specific elements.

Abstract
Sea anemones vary immensely in life history strategies, environmental niches and their ability to regenerate. While the sea anemone Nematostella vectensis is the starlet of many key regeneration studies, recent work is emerging on the diverse regeneration strategies employed by other sea anemones. This manuscript will explore current molecular mechanisms of regeneration employed by non-model sea anemones Exaiptasia diaphana (an emerging model species for coral symbiosis studies) and Calliactis polypus (a less well-studied species) and examine how these species compare to the model sea anemone N. vectensis. We summarize the field of regeneration within sea anemones, within the greater context of phylum Cnidaria and in other invertebrate models of regeneration. We also address the current knowledge on two key systems that may be implemented in regeneration: the innate immune system and developmental pathways, including future aspects of work and current limitations.

Molecular mechanisms of wound healing and regeneration of siphon in the Manila clam Ruditapes philippinarum revealed by transcriptomic analysis. Genomics 2021; 113:1011-1025. [PMID: 33626340 DOI: 10.1016/j.ygeno.2021.02.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2020] [Revised: 01/24/2021] [Accepted: 02/18/2021] [Indexed: 10/22/2022]
Abstract
Ruditapes philippinarum is an economically important marine shellfish aquaculture species, and it has the ability to regenerate its siphons. To gain a greater understanding of the molecular mechanisms at work during siphon regeneration and to provide evidence for morphological regeneration, we examined transcriptome responses of siphon tissue of R. philippinarum during regeneration and observed regenerative siphons under the stereomicroscope. The overall process of siphon regeneration was dissected based on the morphological changes of siphon and the identification of up-regulated key differentially expressed genes (DEGs). The protein biosynthesis and metabolism played important roles in wound healing and siphon regeneration of R. philippinarum. Transcriptomic analysis identified the Wnt and TGF-β signaling pathways by focusing on the function and expression pattern of genes in these pathways during siphon regeneration. In addition, we carried out a genome-wide identification and phylogenetic analysis of TGF-β superfamily in R. philippinarum. The expression profiles of the TGF-β superfamily genes were analyzed in eight adult tissues (adductor muscle, mantle, foot, gill, siphon, digestive gland, gonad, and labial palp) and regenerative siphon. This study shed new light on the process of morphological regeneration and regenerative mechanism of siphon of R. philippinarum.
