Abstract
There is increasing interest in the African spiny mouse (Acomys cahirinus) as a model organism because of its ability for regeneration of tissue after injury in skin, muscle, and internal organs such as the kidneys. A high-quality reference genome is needed to better understand these regenerative properties at the molecular level. Here, we present an improved reference genome for A. cahirinus generated from long Nanopore sequencing reads. We confirm the quality of our annotations using RNA sequencing data from 4 different tissues. Our genome is of higher contiguity and quality than previously reported genomes from this species and will facilitate ongoing efforts to better understand the regenerative properties of this organism.

Abstract
Regenerative wound healing involves the scarless wound healing as observed in fetal skin. Multiple features of regenerative wound healing have been well studied; however, the practical application of pro-regenerative materials to recapitulate the regenerative wound healing in adult skins has not yet been achieved. In this study, the authors identified that their novel pro-regenerative material, pyrogallol-functionalized hyaluronic acid (HA-PG) patches in combination with protein transduction domain-fused Dishevelled (Dvl)-binding motif (PTD-DBM), a peptide inhibiting the CXXC-type zinc finger protein 5 (CXXC5)-Dvl interaction, promoted regenerative wound healing in mice. The HA-PG patches loaded with this competitor peptide and valproic acid (VPA), a glycogen synthase kinase 3β (GSK3β) inhibitor, significantly inhibited scar formation during wound healing. The HA-PG patches with PTD-DBM and/or VPA inhibit the expression of differentiated cell markers such as α-smooth muscle actin (α-SMA) while inducing the expression of stem cell markers such as CD105 and Nestin. Moreover, Collagen III, an important factor for regenerative healing, is critically induced by the HA-PG patches with PTD-DBM and/or VPA, as also seen in VPA-treated Cxxc5-/- mouse fibroblasts. Overall, these findings suggest that the novel regeneration-promoting material can be utilized as a potential therapeutic agent to promote both wound healing and scar attenuation.

Abstract
Chronic diabetic wounds are a growing threat globally. Many aspects contribute to its deterioration, including bacterial infection, unbalanced microenvironment, dysfunction of cell repair, etc. In this work, we designed a multipronged micelles-hydrogel platform loaded with curcumin and rifampicin (CRMs-hydrogel) for bacteria-infected chronic wound treatment. The curcumin- and rifampicin-loaded micelles (CRMs) exhibited both MMP9-responsive and epidermal growth factor receptor (EGFR)-targeting abilities. On the one hand, drugs could be released from micelles due to responsive disassembly by MMP9, a matrix metalloproteinase overexpressed in a chronic wound environment; on the other hand, CRMs showed specific targeting to EGFR on epithelial cells and fibroblasts and therefore increased intracellular drug delivery. The thermosensitive CRMs-hydrogel could form strong adhesion with the wound area and served as a suitable matrix for sustained release of CRMs directly at the wound bed, with excellent intracellular and extracellular bacterial elimination efficiency and wound healing promotion capability. We found that a single dose of CRMs-hydrogel achieved 99% antibacterial rate at the MRSA-infected diabetic wound, which effectively reduced inflammatory response and promoted the neovascularization and re-epithelialization process, with nearly half reduction of the skin barrier regeneration period. Collectively, our thermosensitive, MMP9-responsive, and targeted micelles-hydrogel nanoplatform is promising for chronic wound treatment.

Abstract
Significance: In adult mammals, spontaneous repair of a cutaneous wound occurs slowly and leaves a scar with skin adnexa deficiencies. To accelerate cutaneous wound-healing rates and avoid scar formation, current studies have focused on regenerative therapies. Recent Advances: Emerging therapeutics for regenerative wound healing often focus on the use of growth factors and stem cells. However, these therapeutic approaches have limited routine clinical use due to high costs and technical requirements. Critical Issue: Understanding the molecular mechanisms involved in the signaling pathways for cutaneous wound healing and neogenic synthesis of the skin components is important for identification of novel targets for the development of regenerative wound-healing agents. Future Directions: The Wnt/β-catenin pathway is a well-known key player for enhancement of the overall healing process involving tissue regeneration via crosstalk with other signaling pathways. Strategies that activate the Wnt/β-catenin pathway via modulation of the pathway-controlling regulatory factors could provide effective therapeutic approaches for regenerative wound healing.

Abstract
Novel bionanocatalysts have opened a new era in fighting multidrug‐resistant (MDR) bacteria. They can kill bacteria by elevating the level of reactive oxygen species (ROS) in the presence of chemicals like H2O2. However, ROSs’ ultrashort diffusion distance limit their bactericidal activity. We present a nanohook‐equipped bionanocatalyst (Ni@Co‐NC) with bacterial binding ability that shows robust ROS‐generating capacity under physiological H2O2 levels. The Ni@Co‐NC's pH‐dependent performance confines its effects to the biofilm microenvironment, leaving healthy tissue unaffected. Furthermore, it can generate heat upon NIR laser irradiation, enhancing its catalytic performance while achieving heat ablation against bacteria. With the Ni@Co‐NC's synergistic effects, bacterial populations fall by >99.99 %. More surprisingly, the mature biofilm shows no recurrence after treatment with the Ni@Co‐NC, demonstrating its tremendous potential for treating MDR bacterial related infections.

Abstract
Objective: To design and validate a novel murine model of full-thickness (FT) vaginal wound healing that mirrors postinjury tissue repair and underscores the impact of estrogen signaling-driven healing kinetics, inflammation, and neovascularization. Approach: Five-week-old female CD1 mice were subjected to two 1-mm FT wounds. To assess wound healing kinetics, vaginas were harvested at 6, 12, 18, 24, 48, and 72 h and 7 days postinjury. Wounds from all time points were analyzed by hematoxylin and eosin and trichrome to, respectively, assess the rate of wound closure and tissue deposition. Inflammatory leukocyte (CD45), neutrophil (Ly6G), and macrophage (F480 and CD206) infiltration was examined by immunohistochemistry (IHC) and the resulting anti-inflammatory M2 (CD206)/total (F480) macrophage ratio quantified. Neovascularization (CD31) and estrogen receptor-α (ERα) expression levels were similarly determined by IHC. Results: We observed rapid healing with resolution of mucosal integrity by 48 h (p < 0.05), and overall neutrophils and polarized type 2 macrophages (M2) apexed at 12 h and reduced to near control levels by day 7 postinjury. Tissue repair was virtually indistinguishable from the surrounding vagina. CD31+ vessels increased between 12 h and day 7 and ERα trended to decrease at 12 h postinjury and rebound at day 7 to uninjured levels. Innovation: A proof-of-concept murine model to study vaginal wound healing kinetics and postinjury regenerative repair in the vagina was developed and verified. Conclusion: We surmise that murine vaginal mucosal repair is accelerated and potentially regulated by estrogen signaling through the ERα, thus providing a cellular and molecular foundation to understand vaginal healing responses to injury.
