Summary
March’s cosmetic research was dominated by translational biomaterials and function-first reconstruction, led by a phase II randomized intra-patient controlled trial showing a tissue-engineered autologous dermo-epidermal graft (denovoSkin) improves scar quality. A prospective functional abdominal wall reanimation for Prune Belly Syndrome shifted reconstructive aims from contour to measurable physiology. Regenerative scaffolds (silk-fibroin/GelMA) accelerated healing, reduced scarring, and even induced hair follicle neogenesis, while microneedle-delivered biologics advanced in preclinical hair-regeneration pipelines. On the diagnostic front, plasma neurofilament light chain emerged as a minimally invasive biomarker for diabetic retinopathy progression and vascular risk, complementing ongoing advances in intraoperative imaging and product-safety analytics.

1. Safety and efficacy of bio-engineered, autologous dermo-epidermal skin grafts in reconstructive surgery: 1-year results of a prospective, randomized, intra-patient controlled, multicenter phase II clinical trial.
In a multicenter phase II randomized intra-patient controlled trial (n=23), denovoSkin™, a bio-engineered autologous dermo-epidermal graft cultured in an extracellular matrix, produced significantly better observer-rated scar quality at 3 months versus paired split-thickness skin grafts, with demonstrated feasibility and safety over 1 year.
Impact: Provides randomized, intra-patient controlled clinical evidence that a tissue-engineered autologous skin substitute can improve scar outcomes and reduce donor-site morbidity compared with standard split-thickness grafting.
Clinical Implications: Surgeons treating full-thickness defects and burn scars should consider denovoSkin as a potential alternative to STSG pending phase III confirmation; it may reduce donor morbidity and improve cosmetic scar outcomes—important in reconstructive planning and patient counseling.
Key Findings
- Randomized intra-patient controlled multicenter phase II design with 23 patients receiving both denovoSkin and STSG on comparable wounds.
- Observer-rated POSAS total score at 3 months favored denovoSkin (23.4) over STSG (27.9), indicating improved scar quality.
- Feasibility and safety were maintained over 1 year of follow-up.
2. Functional Reconstruction of Abdominal Wall in Prune Belly Syndrome Using Vastus Lateralis Muscle Flaps: A Prospective Observational Study.
A prospective series describes bilateral pedicled, innervated vastus lateralis musculo-fascial flap transfers to recreate rectus abdominis vectors in Prune Belly Syndrome. Objective EMG and motor testing confirmed active contraction, improved core function, and reduced symptoms linked to inadequate intra-abdominal pressure (eg, constipation, respiratory infections).
Impact: Presents the first reproducible dynamic reanimation of the anterior abdominal wall in a rare congenital disorder with objective functional endpoints, shifting reconstructive goals from contour to physiology.
Clinical Implications: Provides a function-first surgical option for PBS that may restore cough, defecation, and postural control; adoption will require multidisciplinary planning, attention to donor-site morbidity, and standardized rehabilitation protocols.
Key Findings
- Bilateral pedicled, innervated vastus lateralis flaps recreated rectus abdominis functional vectors enabling dynamic contraction.
- EMG and motor testing confirmed active muscle contraction with improved core function.
- Patients experienced reductions in symptoms related to low intra-abdominal pressure (eg, constipation, respiratory infections).
3. Integrated intraocular-plasma proteomics reveals conserved biomarkers for diabetic retinopathy progression: a multi-fluid biopsy study.
High-throughput proteomics of aqueous humour, cross-cohort validation, single-cell mapping, and large-scale prospective analysis in the UK Biobank identified plasma neurofilament light chain (NFL) as a conserved, minimally invasive biomarker that discriminates prevalent diabetic retinopathy and predicts incident DR and vascular complications over 12 years.
Impact: Delivers a validated, blood-detectable marker for diabetic retinopathy progression with prognostic value for systemic vascular events, bridging ocular discovery to scalable clinical screening.
Clinical Implications: Plasma NFL could be integrated into screening and risk-stratification pathways to prioritize ophthalmology referral and preventive strategies for patients with diabetes, pending assay standardization and multi-population validation.
Key Findings
- Discovery proteomics identified 40 candidates with monotonic changes; 25 conserved in validation cohorts.
- Single-cell mapping localized NFL to retinal neurons and glia.
- Baseline plasma NFL associated with prevalent DR (OR 1.98) and predicted incident DR (HR 2.01) and micro/macrovascular events over median 12-year follow-up.
4. Silk fibroin nanofibers-GelMA hydrogel composite loaded with embryonic fibroblasts: A strategy for enhanced wound healing.
A bilayer GelMA/silk-fibroin composite scaffold engineered as a cell-delivery platform supported mouse embryonic fibroblast viability and ECM activity, improved hydrogel mechanics and water retention, accelerated re-epithelialization and angiogenesis in full-thickness wounds, reduced pathological scarring, and induced wound-induced hair follicle neogenesis in vivo.
Impact: Demonstrates a translational biomaterials platform that not only accelerates closure but also improves tissue organization and appendage regeneration—addressing major unmet needs in aesthetic and reconstructive wound care.
Clinical Implications: If validated in human-compatible cells and larger models, this scaffold approach could enable dressings that reduce scar formation and restore hair-bearing function, improving cosmetic outcomes and reducing revision procedures in complex wounds and reconstructions.
Key Findings
- SF nanofiber incorporation improved GelMA compressive strength, water retention, and structural stability.
- MEF-laden GelMA/SF supported high cell viability, increased proliferation and ECM synthesis in vitro.
- In murine full-thickness wounds the composite modulated inflammation, enhanced re-epithelialization and angiogenesis, promoted organized collagen deposition, reduced scarring, and induced hair follicle neogenesis.
5. Evaluation of oncologic safety and clinical effectiveness of immediate autologous fat grafting in breast-conserving surgery: a multicenter, prospective, randomized controlled clinical trial for breast cancer.
Multicenter RCT (n=360) with median 62.8 months follow-up found that immediate autologous fat grafting (IAFG) at breast-conserving surgery did not increase locoregional or distant recurrence or disease-specific mortality, and significantly improved patient-reported breast appearance satisfaction, psychosocial and sexual well-being.
Impact: Addresses a longstanding clinical safety question with high-quality randomized evidence and shows clear patient-centered benefits, changing the risk–benefit calculus for oncoplastic choices.
Clinical Implications: IAFG can be offered during breast-conserving surgery to improve cosmetic and psychosocial outcomes without increasing recurrence risk; counseling should include expected satisfaction gains and standardize grafting/imaging follow-up protocols.
Key Findings
- No increase in local relapse with IAFG vs control (0.6% vs 2.4%; P=0.65).
- No difference in distant recurrence (3.6% vs 3.5%) or breast cancer-specific mortality (0.6% vs 0.6%).
- Significant improvements in patient-reported outcomes: breast appearance, psychosocial and sexual well-being (all P<0.001).
