Zaraisky AG, Araslanova KR, Shitikov AD, Tereshina MB. Loss of the ability to regenerate body appendages in vertebrates: from side effects of evolutionary innovations to gene loss. Biol Rev Camb Philos Soc 2024; 99:1868-1888. [PMID: 38817123 DOI: 10.1111/brv.13102] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2023] [Revised: 05/04/2024] [Accepted: 05/14/2024] [Indexed: 06/01/2024]
Abstract
The ability to regenerate large body appendages is an ancestral trait of vertebrates, which varies across different animal groups. While anamniotes (fish and amphibians) commonly possess this ability, it is notably restricted in amniotes (reptiles, birds, and mammals). In this review, we explore the factors contributing to the loss of regenerative capabilities in amniotes. First, we analyse the potential negative impacts on appendage regeneration caused by four evolutionary innovations: advanced immunity, skin keratinization, whole-body endothermy, and increased body size. These innovations emerged as amniotes transitioned to terrestrial habitats and were correlated with a decline in regeneration capability. Second, we examine the role played by the loss of regeneration-related enhancers and genes initiated by these innovations in the fixation of an inability to regenerate body appendages at the genomic level. We propose that following the cessation of regenerative capacity, the loss of highly specific regeneration enhancers could represent an evolutionarily neutral event. Consequently, the loss of such enhancers might promptly follow the suppression of regeneration as a side effect of evolutionary innovations. By contrast, the loss of regeneration-related genes, due to their pleiotropic functions, would only take place if such loss was accompanied by additional evolutionary innovations that compensated for the loss of pleiotropic functions unrelated to regeneration, which would remain even after participation of these genes in regeneration was lost. Through a review of the literature, we provide evidence that, in many cases, the loss in amniotes of genes associated with body appendage regeneration in anamniotes was significantly delayed relative to the time when regenerative capability was lost. We hypothesise that this delay may be attributed to the necessity for evolutionary restructuring of developmental mechanisms to create conditions where the loss of these genes was a beneficial innovation for the organism. Experimental investigation of the downregulation of genes involved in the regeneration of body appendages in anamniotes but absent in amniotes offers a promising avenue to uncover evolutionary innovations that emerged from the loss of these genes. We propose that the vast majority of regeneration-related genes lost in amniotes (about 150 in humans) may be involved in regulating the early stages of limb and tail regeneration in anamniotes. Disruption of this stage, rather than the late stage, may not interfere with the mechanisms of limb and tail bud development during embryogenesis, as these mechanisms share similarities with those operating in the late stage of regeneration. Consequently, the most promising approach to restoring regeneration in humans may involve creating analogs of embryonic limb buds using stem cell-based tissue-engineering methods, followed by their transfer to the amputation stump. Due to the loss of many genes required specifically during the early stage of regeneration, this approach may be more effective than attempting to induce both early and late stages of regeneration directly in the stump itself.

Abstract
Successful translation of in vivo experimental data to human patients is an unmet need and a bottleneck in the development of effective therapeutics. Organ-on-Chip technology aims to address this need by leveraging recent significant advancements in microfabrication and biomaterials, which enable modeling of organs and their functionality. These microengineered chips offer researchers the possibility to recreate critical elements of native tissue architecture such as in vivo relevant tissue-tissue interface, air-liquid interface, and mechanical forces, including mechanical stretch and fluidic shear stress, which are crucial to recapitulate tissue level functions. Here, we present the development of a new, comprehensive 3D cell-culture system, where we combined our proprietary Organ-Chip technology with the advantages offered by three-dimensional organotypic culture. Leveraging microfabrication techniques, we engineered a flexible chip that consists of a chamber containing an organotypic epithelium, surrounded by two vacuum channels that can be actuated to stretch the hydrogel throughout its thickness. Furthermore, the ceiling of this chamber is a removable lid with a built-in microchannel that can be perfused with liquid or air and removed as needed for direct access to the tissue. The bottom part of this chamber is made from a porous flexible membrane which allows diffusive mass transport to and from the microfluidic channel positioned below the membrane. This additional microfluidic channel can be coated with endothelial cells to emulate a blood vessel and recapitulate endothelial interactions. Our results show that the Open-Top Chip design successfully addresses common challenges associated with the Organs-on-Chip technology, including the capability to incorporate a tissue-specific extracellular matrix gel seeded with primary stromal cells, to reproduce the architectural complexity of tissues by micropatterning the gel, and to extract the gel for H&E staining. We also provide proof-of-concept data on the feasibility of using the system with primary human skin and alveolar epithelial cells.

Abstract
Quality control of tissues and organs for transplant is important to confirm their safety and effectiveness for regenerative medicine. However, quality evaluation is only carried out using a limited range of inspection criteria, because many of the available evaluation tests are invasive. In order to explore the potential of 2-[18F]fluoro-2-deoxy-D-glucose ([18F]FDG)-bioradiography as a non-invasive test for estimation of the safety, soundness, and effectiveness of tissues for transplantation, [18F]FDG uptake and cell viability or metabolism were investigated using a reconstructed human epidermal model (RHEM). We developed an imaging system, and suitable bioradiographic image acquisition conditions and its effectiveness were investigated. [18F]FDG uptake increased in agreement with DNA content as a marker of cell numbers and for histological assessment during cell proliferation and keratinization. [18F]FDG uptake was significantly decreased in good agreement with the viability of tissues used with various hazardous chemical treatments. [18F]FDG uptake by the tissues was decreased by hypothermia treatment and increased by hypoxia treatment while maintaining cell viability in the tissue. Therefore, [18F]FDG-bioradiography can be useful to estimate cell viability or metabolism in this RHEM. This method might be utilized as a non-invasive test for quality evaluation of tissues for transplantation.

Efficacy of Cultured Epithelial Autograft after Curettage for Giant Melanocytic Nevus of the Head. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2018; 6:e1827. [PMID: 30276054 PMCID: PMC6157934 DOI: 10.1097/gox.0000000000001827] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2018] [Accepted: 04/18/2018] [Indexed: 11/26/2022]
Abstract
Supplemental Digital Content is available in the text. Cultured epithelial autograft (CEA) is an epithelial sheet prepared from a patient’s own skin using cell culture. In Japan, CEA (JACE; Japan Tissue Engineering Co., Ltd., Gamagori, Japan) was approved and covered by public health care insurance for use in the treatment of giant congenital melanocytic nevus (GCMN) in 2016. There are several treatment options for GCMN; however, the complete removal of a GCMN is usually difficult due to the lack of skin. In this report, we describe a case of GCMN in the occipital region that was treated using CEA after curettage. A 2-month-old boy had a GCMN of 13 × 21 cm in his occipital region. We used full-thickness skin taken from the back of the right auricle to prepare CEA under general anesthesia at 4 months of age. Three weeks after preparing CEA, we performed curettage of the right half of the GCMN, and CEA was grafted onto the wound afterward. CEA took completely, and epithelization was observed at 10 days after surgery. We then performed curettage with subsequent grafting of CEA on the left half of the GCMN at 7 months of age. CEA took completely, and epithelization was observed in this procedure as well with no hair loss at 8 months of age. Whether or not curettage can reduce the risk of malignant transformation into malignant melanoma of GCMN is unclear; however, the application of CEA after curettage may be a promising option for obtaining early epithelization.

Harvesting epithelial keratinocyte sheets from temperature-responsive dishes preserves basement membrane proteins and improves cell survival in a skin defect model.

Abstract
Cultured epithelial autograft (CEA) therapy has been used in clinical applications since the 1980s. However, there are some issues related to this treatment that still remain unsolved. Enzymatic treatment is typically used in the collection of epithelial keratinocyte sheets, but it tends to break the adhesion and basement membrane proteins. It is thought that the loss of proteins after enzymatic treatment is responsible for the poor survival of transplanted cell sheets. Our laboratory has developed a temperature-responsive culture dish that does not require enzymatic treatment to harvest the cells. In this study, we compare morphological and survival results from rat epithelial keratinocyte cell sheets harvested by temperature-reducing treatment (TT sheets) against cell sheets harvested by enzymatic (dispase) treatment (DT sheets). TT sheets preserve keratin structure in better conditions and express higher levels of collagen IV and laminin 5 than DT sheets. In order to evaluate cell sheet survival after transplantation, we created an in vivo transplant model. Keratinocyte sheets obtained from GFP-positive animals were transplanted into athymic rats. The survival rate 7 days after transplantation of TT sheet was higher than that of DT sheets. Collagen IV and Laminin 5 expression was observed in the TT sheet transplantation group. These results indicate that the remaining basement membrane proteins are important for initial attachment and cell survival. We believe that the cell sheet harvesting method using temperature-responsive culture dishes provides superior cell survival and can solve one of the roadblocks in CEA therapy.
