Background: Use of dermal regeneration template (DRT) is well documented in the literature for complex wounds ranging from the scalp, trunk, and lower extremity.
Methods: A retrospective cohort study was performed of the use of dermal regeneration template and skin grafting. A literature review was performed of all studies where DRT was used for scalp reconstruction.
Results: Patients in the DRT cohort had an average age of 70, with wounds averaging 108 cm in size. These patients also had a relatively low rate of complications (0.4), a short hospital stay (average 2 days), and a relatively short operating room time (114 minutes).
Conclusion: This study demonstrates dermal regeneration template to be an effective and reliable option for soft tissue reconstruction with minimal morbidity and complications in patients with extensive medical comorbidities. Emerging applications include radiation exposure and hypercoaguable states.

Background: Tissue expansion is a widely employed technique in reconstructive surgery aimed at addressing considerable skin defects. Nevertheless, matters like inadequate expansion capability and the potential for skin breakage due to the fragility of the expanded tissue present notable hurdles in enhancing skin regeneration during this process. Angiotensin-converting enzyme 2 (ACE2) is recognized for its essential role in facilitating tissue renewal and regeneration.

Existing treatments for androgenetic alopecia (AGA) are unsatisfactory, owing to the two major reasons: (1) Oxidative stress and vascularization deficiency in the perifollicular environment provoke the premature senescence of hair follicles, limiting transformation from the telogen to the anagen phase; (2) The amount of drug delivered to the perifollicular region located in the deep dermis is very limited for passive drug delivery systems. Herein, we developed a gas-propelledmicroneedle patch integrated with ferrum-chelated puerarin/quercetin nanoparticles (PQFN) to increase drug accumulation in hair follicles and reshape the perifollicular environment for improved hair-regenerating effects. PQFN can rejuvenate testosterone (Tes)-induced senescence of dermal papilla cells by scavenging ROS, restoring mitochondrial function, regulating signaling pathways related to hair regeneration, and upregulating hair growth-promoting genes.

Introduction: Non-healing wounds pose significant challenges and require effective therapeutic interventions. Extracellular vesicles (EVs) have emerged as promising cell-free therapeutic agents in tissue regeneration. However, the functional differences between different subpopulations of EVs in wound healing remain understudied.

Background: Postsurgical atrophic scars tend to respond poorly to treatments, especially non-energy-based ones. Hydrophilic PN HPT (Polynucleotides High Purification Technology) injected intradermally is a non-energy-based option with an immediate volume-enhancing effect that indirectly improves the fibroblast synthesis of collagen and extracellular matrix. The PN HPT ingredient has the further benefit of a dermal "priming" effect that enhances the efficacy of other scar treatments.
