Summary
Mechanobiology and safety dominate today’s cosmetic-focused literature. A preclinical study reveals that mechanical pressure disrupts a porous survival architecture in large-volume fat grafts, driving YAP-linked latent injury and later fibrosis.

1. Porous Architecture and Pressure-Induced Latent Injury: New Insights into Large-Volume Fat Grafting.
A 3D human adipose model showed that a pressure-sensitive porous interstitial network supports survival to ~8 mm; pressure progressively collapsed this network, reducing solute permeability (76.4% to 21.3%) and cell viability with YAP-linked mechanotransduction and metabolic stress. In mice, pressure-conditioned grafts had similar gross retention but developed marked necrosis and higher fibrosis (to 53.3% at 8 weeks). Minimizing mechanical stress across the fat grafting workflow may reduce late fibrosis.
Impact: It introduces a mechanistic framework for why large-volume fat grafts fibrose despite apparent survival, linking pressure-induced architectural failure to YAP-mediated latent injury.
Clinical Implications: Adopt pressure-minimizing strategies during harvest, processing, and implantation (e.g., gentle aspiration, low-pressure handling, atraumatic cannulas, minimizing overpacking) and consider mechanotransduction-targeted adjuncts to decrease late fibrosis.
Key Findings
- Porous interstitial network supports survival to ~8 mm depth in large-volume fat constructs.
- Mechanical pressure collapses this network dose-dependently, reducing solute permeability from 76.4% to 21.3% and impairing viability.
- Pressure induces YAP-linked mechanotransductive signaling with lineage/metabolic stress signatures consistent with latent injury.
- In vivo, pressure-conditioned grafts show similar gross volume retention but increased necrosis and fibrosis (control 22.1% vs 12 mmHg 53.3% at 8 weeks).
Methodological Strengths
- Integrated 3D human adipose scaffold model with quantitative permeability/viability readouts and in vivo validation.
- Dose–response assessment of controlled pressures (0, 6, 12 mmHg) with molecular pathway analyses (YAP signaling).
Limitations
- Preclinical in vitro/in vivo models may not capture all clinical variables of human grafting.
- Follow-up limited to 8 weeks; long-term remodeling and human confirmation are needed.
Future Directions: Evaluate pressure-limiting devices/workflows in clinical fat grafting; test mechanotransduction inhibitors (e.g., YAP–TEAD modulators) to mitigate latent injury and fibrosis.
BACKGROUND: Large-volume autologous fat grafting for aesthetic augmentation is often complicated by cysts and fibrosis, suggesting that its survival mechanisms differ from those of small-volume grafts. OBJECTIVES: To investigate the survival biology of large-volume fat grafts and evaluate the effects of mechanical pressure on tissue structure, viability, and long-term graft outcome. METHODS: A 3-dimensional in vitro model using human adipose tissue in a scaffold was established. Constructs were cultured under 0, 6 or 12 mmHg of pressure to assess structural integrity, solute permeability, cell viability and molecular changes. The viable outer layer was then transplanted into nude mice to evaluate volume retention, necrosis and fibrosis. RESULTS: In vitro, a porous interstitial network supported tissue survival to a depth of approximately 8 mm. Pressure dose-dependently disrupted this network, reducing solute permeability from 76.4% to 21.3% and impairing viability. Pressure also induced a form of "latent injury," consistent with YAP-related mechanotransductive signaling, lineage-related molecular changes and metabolic stress. In vivo, although gross volume retention was similar among groups, pressure-conditioned grafts developed marked necrosis, with fibrosis increasing from 22.1% in controls to 53.3% in the 12 mmHg group at 8 weeks. CONCLUSIONS: Large-volume fat graft survival depends in part on the integrity of a pressure-sensitive porous network. Mechanical pressure may induce a clinically relevant "latent injury," consistent with molecular changes observed in vitro, which may contribute to later fibrosis. Minimizing mechanical stress during harvest, processing, handling and implantation may help preserve graft integrity and improve long-term outcomes.
2. RSM-Optimized Ultrasonic-Assisted Extraction for High-Efficiency Recovery of Pb, Cd, and As in Complex Systems.
A green, ultrasonic-assisted extraction coupled to AAS was optimized via response surface methodology to rapidly recover Pb, Cd, and As from complex matrices including cosmetic products. Ultrasonic cavitation improved desorption and mass transfer under mild conditions with reduced reagents, and RSM identified nitric acid concentration and solvent volume as key factors with strong model predictivity.
Impact: Provides a scalable, greener analytical workflow to surveil toxic metals across consumer products, directly supporting regulatory compliance and cosmetic safety.
Clinical Implications: Improved surveillance of Pb/Cd/As in cosmetic products can reduce exposure risk by enabling faster QA/QC responses, recalls, and supplier controls.
Key Findings
- Ultrasonic cavitation enabled rapid extraction of Pb, Cd, and As from complex matrices including cosmetic products under mild, greener conditions.
- Response surface methodology (rotatable central composite design) optimized nitric acid concentration (0.40–1.20 M), ultrasonic time (5–15 min), and acid volume (20–40 mL).
- Modeling showed strong predictivity and identified acid concentration and solvent volume as the most significant factors for metal recovery.
Methodological Strengths
- Response surface methodology with rotatable central composite design for rigorous multivariate optimization.
- Application across diverse real-world matrices (herbals, cosmetics, beverages, wastewater) enhances generalizability.
Limitations
- Abstract truncation precludes reporting specific limits of detection, precision, and recovery percentages.
- Validation in accredited laboratories and inter-lab reproducibility were not detailed.
Future Directions: Extend validation to certified reference materials and inter-laboratory trials; integrate with ICP-MS for speciation where needed; develop portable workflows for field surveillance.
Toxic trace metals such as lead (Pb), cadmium (Cd), and arsenic (As) represent persistent environmental contaminants associated with significant human health risks. Reliable and rapid analytical strategies are therefore essential for toxicological surveillance of consumer and environmental matrices. In this study, a green and process-intensified ultrasonic extraction method was developed for the efficient recovery and determination of Pb, Cd, and As from complex matrices including herbal materials, cosmetic products, beverages, and wastewater, using Atomic Absorption Spectrometry. The approach utilizes ultrasonic cavitation to accelerate metal desorption and mass transfer, enabling rapid extraction under mild conditions with reduced reagent consumption. Galangal was selected as a representative plant matrix to establish and validate the analytical framework. A rotatable central composite design based on response surface methodology was applied to evaluate the influence of nitric acid concentration (0.40-1.20 M), ultrasonic time (5-15 min), and acid volume (20-40 mL) on metal recovery. The statistical model demonstrated strong predictive capability and identified acid concentration and solvent volume as significant factors influencing extraction performance (

Extracellular vesicles (EVs) are nanosized lipid bilayer particles naturally secreted by cells, mediating intercellular communication and transporting diverse bioactive molecules. Among alternative EV sources, bovine milk-derived EVs (BMEVs) have emerged as promising platforms for drug delivery due to their accessibility, scalability, stability and promising biocompatibility, although their long-term safety profile, particularly for engineered or cargo-loaded formulations, still requires further investigation. BMEVs can encapsulate small molecules, natural polyphenols and nucleic acids, enhancing bioavailability, protecting cargo from degradation and facilitating functional delivery. Recent studies demonstrate their potential for oral administration and their intrinsic therapeutic properties, including antioxidant, anti-inflammatory, and immunomodulatory activities. Moreover, the increasing number of patents highlights their translational and commercial relevance in therapeutic, cosmetic and nutraceutical applications. Despite these promising features, challenges remain in standardizing isolation protocols, optimizing cargo loading, ensuring batch reproducibility and evaluating long-term safety. Addressing these gaps is essential to enable clinical translation and establish BMEVs as versatile drug delivery platforms.
