1. Lipoic Acid-Intervened Decellularized Stem Cell Spheroid-Based Injectable Granular Gel for Diabetic Tissue Regeneration.
The authors engineered lipoic acid–enhanced, decellularized ADSC spheroids into an injectable granular gel with strong immunomodulatory activity and ECM-supporting properties, enabling assembly into a viscoelastic biomaterial. In diabetic rat models, the gel promoted closure of skin wounds and cranial defects, supporting a cell-free regenerative strategy.
Impact: Introduces a cell-free, bioactive granular gel that overcomes immunogenicity and manufacturing barriers of cell therapies while achieving regeneration in two diabetic models.
Clinical Implications: If validated in large animals and humans, this off-the-shelf injectable could expand reconstructive options for chronic diabetic wounds and cranial defects, reducing reliance on viable cell therapies.
Key Findings
- Lipoic acid re-engineered ADSC spheroids to enhance paracrine signaling and ECM biosynthesis before decellularization.
- Decellularized spheroids self-assembled into an injectable granular gel with immunomodulatory activity, including macrophage reprogramming signals.
- In diabetic rat models, the material supported closure of both cutaneous wounds and cranial defects.
Methodological Strengths
- Multi-system validation with in vitro mechanistic assays and two distinct in vivo diabetic models
- Cell-free, decellularized approach reduces immunogenicity and improves translational potential
Limitations
- Preclinical evidence without human data; long-term safety, degradation, and efficacy durability remain unknown
- Manufacturing scalability, batch consistency, and regulatory pathways are not addressed
Future Directions: Evaluate long-term safety and efficacy in large-animal diabetic wound and bone defect models, define mechanism of macrophage reprogramming, and initiate first-in-human feasibility studies.
Advancements in tissue engineering have revolutionized therapeutic paradigms for diabetic tissue defects; however, the lack of applicable scaffold containing various bioactive substance aggregates remained a critical bottleneck hindering satisfactory repair effect. In this study, adipose-derived stem cells (ADSCs) were functionally re-engineered using lipoic acid (LA) to fabricate a novel LA-intervened stem cell spheroid (LA-SCS) with enhanced paracrine activity and extracellular matrix (ECM) biosynthetic capacity. Subsequent decellularization mitigated immunogenicity, yielding LA-intervened decellularized stem cell spheroid (LA-dSCS). In vitro assays confirmed its immunomodulatory potency, as evidenced by the activation of signaling cascades associated with macrophage reprogramming, homeostasis, and autophagy. Furthermore, leveraging the intrinsic viscoelastic properties of the LA-dSCS, a convenient preparation method for preparing LA-dSCS derived injectable material was established, wherein LA-dSCS micro-particles assemble into LA-dSCS granular gel. In vivo studies using diabetic rat models demonstrated closure of both wound and cranial defects. Collectively, this study established a biomimetic engineering strategy that integrates cell-free bioactive aggregates with injectable granular gels, offering a novel proof‑of‑concept strategy for the regeneration of complex diabetic tissue defects.
2. Naturally derived polysaccharides and ganoderic acid A hydrogel with whitening potential to combat oxidative stress and melanin production caused by ultraviolet B.
A biocompatible, self-healing hydrogel composed of oxidized Tremella polysaccharide, carboxymethyl chitosan, and ganoderic acid A reduced melanogenesis via antioxidant activity and downregulation of MITF/TRP1/DCT/TYR. Efficacy was shown across in vitro systems, zebrafish (tyrosinase inhibition 68%; melanin reduction 37%), and a 28-day human use test with improved skin tone and pigmentation.
Impact: Demonstrates a natural, multifunctional hydrogel with cross-species evidence and preliminary human data for UVB-induced hyperpigmentation, addressing demand for hydroquinone alternatives.
Clinical Implications: Supports development of a dermocosmetic whitening product leveraging antioxidant and melanogenesis pathway modulation; requires larger, randomized clinical trials to compare with standard depigmenting agents.
Key Findings
- Hydrogel exhibited self-healing, moisturizing capacity, and biocompatibility via Schiff base and hydrogen bonding network.
- Reduced α-MSH secretion in HaCaT, decreased melanin and tyrosinase in B16F10, and downregulated MITF/TRP1/DCT/TYR proteins.
- In zebrafish, tyrosinase inhibition reached 68% and melanin reduction 37%; a 28-day human use test showed significant skin tone improvement and reduced pigmentation.
Methodological Strengths
- Multi-tier evaluation spanning in vitro, zebrafish, and human use testing
- Mechanistic readouts linking antioxidant effects to melanogenesis pathway downregulation
Limitations
- Human study details (sample size, controls, blinding) are not specified; durability and safety beyond 28 days are unknown
- Comparative efficacy versus standard agents (e.g., hydroquinone, arbutin) not assessed
Future Directions: Conduct randomized, controlled human trials with objective colorimetry, safety profiling, and head-to-head comparisons against standard depigmenting agents.
The intersection of natural products and precision skin care has become a new trend in cosmetic development. This study developed a hydrogel composed of oxidized Tremella fuciformis polysaccharide, carboxymethyl chitosan, and Ganoderic acid A. The hydrogel formed a stable network through Schiff base bonds and hydrogen bonding, exhibiting excellent biocompatibility, self-healing properties, and moisturizing capacity. In vitro experiments demonstrated its potential to scavenge ABTS/hydroxyl radicals/UVB-induced ROS, inhibit α-MSH secretion in HaCaT, reduce melanin content and tyrosinase activity in B16F10 cells, and downregulate protein expression of MITF/TRP1/DCT/TYR. The inhibition rate of tyrosinase activity and the melanin inhibition rate in zebrafish reached 68% and 37% at the test concentration, while human trials showed significant skin tone improvement and reduced pigmentation after continuous use for 28 days. This hydrogel provides a novel natural whitening strategy against UVB-induced skin hyperpigmentation.
3. Effectiveness of a Workplace Web-Based Multi-Component Intervention on Lifestyle, Health, and Work Productivity in Beauty Consultants: A Randomized Controlled Trial.
In a 12-week RCT among female beauty consultants, a web-based, multi-component program (supervised exercise plus education) significantly improved Mediterranean diet adherence, physical activity, lower-limb strength, back pain, stress, and work productivity versus controls. Effects were statistically significant with large effect sizes.
Impact: Provides randomized evidence that a scalable, digital workplace program can improve health and productivity metrics in a cosmetically oriented workforce.
Clinical Implications: Supports implementing structured web-based wellness programs in beauty industry settings to reduce musculoskeletal pain and stress while enhancing productivity; further larger RCTs should assess durability and cost-effectiveness.
Key Findings
- Intervention group (n=24) improved Mediterranean diet adherence and physical activity compared with controls (all p<0.05).
- Back pain and stress decreased, and lower-limb strength increased in the intervention group (all p<0.05).
- Work productivity significantly improved with large effect sizes in the intervention group versus control.
Methodological Strengths
- Randomized controlled design with pre–post assessments
- Multi-component intervention integrating supervised exercise and lifestyle education
Limitations
- Small sample size (n=48) and single-company, female-only cohort limit generalizability
- Short duration (12 weeks) without long-term follow-up or cost-effectiveness analysis
Future Directions: Scale to multi-site, mixed-gender cohorts with longer follow-up, incorporate objective activity and productivity metrics, and evaluate cost-effectiveness.
OBJECTIVE: To evaluate the effectiveness of a multi-component, web-based workplace intervention targeting lifestyle behaviors, physical and mental health, and work productivity. METHODS: A randomized controlled trial was conducted in female beauty consultants from a cosmetics company. Participants were randomly assigned to an intervention group (IG; n=24) or control group (CG; n=24). The IG completed a 12-week web-based program including supervised exercise and educational content on physical activity, nutrition, stress management, and sleep. Lifestyle behaviors, health outcomes, physical fitness, and work productivity were assessed at baseline and post-intervention. RESULTS: Compared with the CG, the IG showed significant improvements in Mediterranean diet adherence, physical activity, back pain, stress, lower-limb strength, and work productivity (all p<0.05), with large effect sizes. CONCLUSIONS: A 12-week web-based, multi-component workplace intervention significantly improved lifestyle behaviors, health outcomes, and work productivity.
