A fibrotic or pathological scar is an undesired consequence of skin wound healing and may trigger a series of problems. An attenuated inflammatory response is a significant characteristic of fetal skin wound healing, which can contribute to the scarless healing of fetal skin. According to deep sequencing data, microRNA‑149 (miR‑149) expression was increased in mid-gestational compared with that in late‑gestational fetal skin keratinocytes. It was demonstrated that overexpression of miR‑149 in HaCaT cells can downregulate the expression of pro‑inflammatory cytokines interleukin (IL)‑1α, IL‑1β, and IL‑6 at basal levels and in inflammatory conditions...

BACKGROUND: Mammals cannot regenerate the dermis and other skin structures after an injury and instead form a scar. However, a Xenopus laevis froglet can regenerate scarless skin, including the dermis and secretion glands, on the limbs and trunk after skin excision. Subcutaneous tissues in the limbs and trunk consist mostly of muscles. Although subcutaneous tissues beneath a skin injury appear disorganized, the cellular contribution of these underlying tissues to skin regeneration remains unclear...

Protein tagging with a wide variety of epitopes and/or fusion partners is used routinely to dissect protein function molecularly. Frequently, the required DNA subcloning is inefficient, especially in cases where multiple constructs are desired for a given protein with unique tags. Additionally, the generated clones have unwanted junction sequences introduced. To add versatile tags into the extracellular domain of the transmembrane protein THSD1, we developed a protein tagging technique that utilizes non-classical type IIS restriction enzymes that recognize non-palindromic DNA sequences and cleave outside of their recognition sites...

Aggregatibacter actinomycetemcomitans, a Gram-negative bacterium, is the causative agent of localized aggressive periodontitis. Attachment to a biotic surface is a critical first step in the A. actinomycetemcomitans infection process for which exopolysaccharides have been shown to be essential. In addition, the pga operon, containing genes encoding for biosynthetic proteins for poly-N-acetyl glucosamine (PNAG), plays a key role in A. actinomycetemcomitans virulence, as a mutant strain lacking the pga operon induces significantly less bone resorption...

Skin scarring after deep dermal injuries is a major clinical problem due to the current therapies limited to established scars with poor understanding of healing mechanisms. From investigation of aberrations within the extracellular matrix involved in pathophysiologic scarring, it was revealed that one of the main factors responsible for impaired healing is abnormal collagen reorganization. Here, inspired by the fundamental roles of decorin, a collagen-targeting proteoglycan, in collagen remodeling, we created a scar-preventive collagen-targeting glue consisting of a newly designed collagen-binding mussel adhesive protein and a specific glycosaminoglycan...

Natural orifice transluminal endoscopic surgery (NOTES) is a surgical technique to perform "scarless" abdominal operations. Robotic technology has been exploited to improve NOTES and circumvent its limitations. Lack of a multitasking platform is a major limitation. Manual tool exchange can be time consuming and may lead to complications such as bleeding. Previous multifunctional manipulator designs use electric motors. These designs are bulky, slow, and expensive. This paper presents design, prototyping, and testing of a hydraulic robotic tool changing manipulator...

In this opinion paper of the Journal of Endocrinological Investigation, leading experts in the field report on their current clinical experience with a novel approach for thyroid gland surgery, namely, "transoral thyroidectomy" (TOT). This feasible and novel surgical procedure does not require visible incisions and is, therefore, a truly scarless surgery. Patients meeting the following criteria can be considered as candidates for TOT: (a) an ultrasonographically (US) estimated thyroid diameter ≤10 cm; (b) US-estimated gland volume ≤45 mL; (c) nodule size ≤50 mm; (d) presence of a benign tumor such as a thyroid cyst or a single- or multi-nodular goiter; (e) Bethesda 3 and/or 4 category and (f) papillary microcarcinoma without the evidence of metastasis...

BACKGROUND: Bilateral open cervical exploration with identifying all parathyroid glands and removing one or more enlarged parathyroid tumor(s) was the standard of care in primary hyperparathyroidism (pHPT). With the introduction of preoperative imaging and intraoperative parathyroid hormone (IOPTH) measurements [1, 2], various minimally invasive parathyroidectomy approaches have been developed, both open and endoscopic [3-8]. The most commonly used approach currently in the USA is the minimally invasive open parathyroidectomy (MIP), which can be performed in the ambulatory setting with excellent cure and minimal complication rates [9-12]...

Efficient assembly of multiple DNA fragments is a pivotal technology for synthetic biology. A scarless and sequence-independent DNA assembly method (DATEL) using thermal exonucleases has been developed recently. Here, we present a simplified DATEL (sDATEL) for efficient assembly of unphosphorylated DNA fragments with low cost. The sDATEL method is only dependent on Taq DNA polymerase and Taq DNA ligase. After optimizing the committed parameters of the reaction system such as pH and the concentration of Mg(2+) and NAD+, the assembly efficiency was increased by 32-fold...

The development of programmable nucleases has enabled the application of new genome engineering strategies for cellular immunotherapy. While targeted nucleases have mostly been used to knock-out or knock-in genes in immune cells, the scarless exchange of entire immunogenomic alleles would be of great interest. In particular, reprogramming the polymorphic MHC locus could enable the creation of matched donors for allogeneic cellular transplantation. Here we show a proof-of-concept for reprogramming MHC-specificity by performing CRISPR-Cas9-assisted cassette exchange...

INTRODUCTION: Facial burns occur frequently and depending on the injured skin layers often heal with scars which may cause permanent functional and cosmetic sequelae. Preservation of the sensitive facial skin layers, especially of the dermis is essential for scarless epithelialisation. Enzymatic debridement of deep thermal burns has already been shown to assist with preserving viable dermis. However, up to date, there are no published reports on wound healing and in the long term aesthetic outcome after enzymatic debridement of facial burns...

INTRODUCTION: The umbilicus is an important component of body esthetics, and its absence or dysmorphia may give rise to psychological discomfort, making it a common concern in surgical planning. Many techniques of umbilicus reconstruction have been proposed, each with its own limitations in terms of esthetics, risk of stenosis or final positioning. Reconstruction techniques may involve skin grafting, cartilage, purse-string suture and flaps. One of the most promising approaches is scarless neo-umbilicoplasty...

DNA assembly forms the cornerstone of modern synthetic biology. Despite the numerous available methods, scarless multi-fragment assembly of large plasmids remains challenging. Furthermore, the upcoming wave in molecular biological automation demands a rethinking of how we perform DNA assembly. To streamline automation workflow and minimize operator intervention, a non-enzymatic assembly method is highly desirable. Here, we report the optimization and operationalization of a process called Twin-Primer Assembly (TPA), which is a method to assemble polymerase chain reaction-amplified fragments into a plasmid without the use of enzymes...

Monogenic disorders (MGDs), which are caused by single gene mutations, have a serious effect on human health. Among these, β-thalassemia (β-thal) represents one of the most common hereditary hematological diseases caused by mutations in the human hemoglobin β (HBB) gene. The technologies of induced pluripotent stem cells (iPSCs) and genetic correction provide insights into the treatments for MGDs, including β-thal. However, traditional approaches for correcting mutations have a low efficiency and leave a residual footprint, which leads to some safety concerns in clinical applications...

Oral tolerance refers to the specific inhibition of immune responsiveness to T-cell-dependent antigens contacted through the oral route before parenteral immunization. Oral tolerance to one protein does not inhibit immune responses to other unrelated proteins, but parenteral injection of tolerated antigens plus adjuvant into tolerant, but not normal, mice inhibits immune responses to antigens injected concomitantly or soon thereafter. The inhibitory effect triggered by parenteral injection of tolerated proteins is known as bystander suppression or indirect effects of oral tolerance...

Cutaneous wounding in late-gestational fetal or postnatal humans results in scar formation without any skin appendages. Early or mid- gestational skin healing in humans is characterized by the absence of scaring in a process resembling regeneration. Tremendous cellular and molecular mechanisms contribute to this distinction, and fibroblasts play critical roles in scar or scarless wound healing. This review discussed the different repair mechanisms involved in wound healing of fibroblasts at different developmental stages and further confirmed that fetal fibroblast transplantation resulted in reduced scar healing in vivo...

Wound healing is a highly orchestrated physiological process consisting of a complex events, and scarless wound healing is highly desired for the development and application in clinical medicine. Recently, we have demonstrated that human amniotic epithelial cells (hAECs) promoted wound healing and inhibited scar formation through a paracrine mechanism. However, exosomes (Exo) are one of the most important paracrine factors. Whether exosomes derived from human amniotic epithelial cells (hAECs-Exo) have positive effects on scarless wound healing have not been reported yet...

Site-directed scarless mutagenesis is an essential tool of modern pathogenesis research. We describe an optimized two-step protocol for genome editing in Salmonella enterica serovar Typhimurium to enable multiple sequential mutagenesis steps in a single strain. The system is based on the λ Red recombinase-catalyzed integration of a selectable antibiotics resistance marker followed by replacement of this cassette. Markerless mutants are selected by expressing the meganuclease I-SceI which induces double-strand breaks in bacteria still harboring the resistance locus...
