Summary: Puerarin has been shown to promote wound healing by accelerating wound closure rate, increasing keratinocyte proliferation and migration, and enhancing capillary density and collagen fiber levels at the wound sites. Additionally, it activates the ERK and Akt signaling pathways to facilitate keratinocyte function. These findings suggest that puerarin could be a potential treatment for delayed and impaired wound healing caused by dexamethasone.

Summary: In this study, corneal fibroblasts (CFs) with high proliferative potential were isolated and grown in a serum-free medium, and then reverted into keratocytes. These reverted cells maintained the morphology and functional properties of primary keratocytes, making them a potential source for tissue engineering and cell therapy of corneal pathologies.

Summary: In this study, microwell arrays with a grating-patterned bottom were designed and fabricated to systematically investigate the effects of confinement, changes in topography, and cell-cell contacts on the migration behavior of nasopharyngeal carcinoma (NPC43) and immortalized nasopharyngeal epithelial (NP460) cells. The results showed that co-culturing NPC43 and NP460 cells in microwells significantly increased the migration speed and spreading area of NPC43 cells, which can be attributed to heterotypic cell-cell contacts. Moreover, in 3D microwell arrays, NPC43 cells formed clusters on the bottom surface while NP460 cells migrated onto the sidewalls, providing potential applications for drug screening.

Summary: Induced pluripotent stem cells (iPSCs) can secrete microvesicles (MVs) that have the potential for skin healing and rejuvenation. This study evaluated the possibility, safety, and effectiveness of using iPSCs-derived MVs for skin tissue engineering and regeneration. The results showed that MVs can promote skin cell growth and repair, and have beneficial effects on skin regeneration in rat burn wound models.

Summary: Hyperglycemia leads to oxidative stress and fibrosis of the myocardium, which is the main cause of diabetic cardiomyopathy. Metformin has been shown to improve glycemic control and ameliorate diabetic cardiomyopathy. This study aimed to investigate the effects and mechanism of metformin on diabetes-induced cardiac fibrosis and high glucose-induced proliferation of cardiac fibroblasts (CFs).

Summary: Cardiac fibrosis, caused by activation and proliferation of cardiac fibroblasts, remains a challenging problem in heart disease. The gene IGFBP3 was found to be significantly upregulated in cardiac fibrosis, and its knockdown inhibited migration and proliferation of fibroblasts. Additionally, abnormal N6-methyl-adenosine(m6A) mRNA modifications were found to regulate IGFBP3 expression in developing cardiac fibrosis. METTL3 may regulate IGFBP3 expression and fibroblast activation through RNA epigenetic modifications, providing a potential therapeutic target.

Summary: This study aimed to investigate the interaction between S. aureus biofilm and fibroblast cells, searching for potential biomarkers of critical colonization and infection. Advanced microscopy and microbiological methods were utilized to examine biofilm formation and the infection process, identifying metabolites related to the switch to anaerobic metabolism in staphylococcal biofilm co-cultured with fibroblast cells. These findings may be a preliminary step towards developing a new, NMR-based tool for rapid diagnosis of infection in chronic wounds.

Summary: The tumor microenvironment plays a crucial role in cancer initiation and progression. Understanding the interactions between cancer cells and the various components of the tumor microenvironment is essential for developing effective treatment strategies. Co-culture models have been developed to study these interactions, providing insights into the role of the stroma and tumor-stromal interactions.

Summary: Phototherapy, particularly using lasers, can be an effective and minimally invasive treatment option for periodontal and peri-implant diseases. This study examined the effects of different laser wavelengths, power densities, and energy densities on in vitro cultured human gingival fibroblasts. The findings suggest that laser irradiation at a wavelength of 1064nm resulted in the highest increase in cell viability after 48 and 72 hours.

Summary: The study found that inhibiting epidermal cell autophagy impairs wound healing in mice, affecting processes such as keratinocyte proliferation, immune cell infiltration, and dermal tissue formation. TNF induces CCL2 transcription through the autophagy-AMPK-BRAF-MAPK1/3/ERK-AP1 pathway, influencing keratinocyte migration and proliferation, and activating dermal fibroblasts.

Summary: The treatment of skin defects is a challenge in the medical field. Tissue engineering skin provides a new idea for the treatment of injured skin. However, slow vascularization is a problem in tissue engineering due to single seed cells. Cell co-culture technology is studied to simulate the survival and communication environment of cells in the human body. This paper investigates the effects of co-culturing human skin fibroblasts (HSFs) and human vascular endothelial cells (HVECs) on cell activity, migration, and secretion factors. The results show that HVECs can promote cell activity, migration, and secretion factors, improving the success rate of tissue engineering skin.
