Summary: This work aimed to select a Tisochrysis lutea phenotype with higher biomass and fucoxanthin productivities using fluorescence-activated cell sorting (FACS). A novel phenotype was obtained after two rounds of selection, resulting in significantly increased productivity of fucoxanthin and docosahexaenoic acid. The new phenotype showed high potential for industrial production with the highest reported outdoor productivities.

Summary: Liquid biopsy is a minimally invasive alternative to surgical biopsy, which can provide a window into the tumor landscape by analyzing analytes such as extracellular vesicles. Research findings indicate that fractionation of EV subpopulations can lead to transcriptome profiles that are closer to tumorigenic processes, and tumor-specific EVs isolated from plasma show enrichment in GBM-associated genes.

Summary: This study investigates the effects of ultraviolet-induced adipose tissue-derived mesenchymal stem cells and their secreted cytokines and growth factors on wound healing. The results show that mesenchymal stem cells have a protective effect against ultraviolet-induced damage and their secreted factors can enhance cell viability and wound-healing rate. However, further analysis and animal experiments are needed before clinical use.

Summary: This study reveals that ceramide synthesis regulates the content of MALAT1 in extracellular vesicles (sEV) secreted from adipose-derived stem cells (ADSC). Inhibition of sphingomyelinase prevents the secretion of MALAT1 from ADSC sEV. Understanding the function of exosomes and their components, such as MALAT1, is crucial for wound healing.

Summary: Tissue engineering is a cutting-edge discipline that combines cells, scaffolds, and induction factors to regenerate and repair damaged tissue. Understanding the effects of biochemical and biophysical factors on cell fate is crucial for improving the efficiency of tissue engineering approaches. Biophysical signals provide a robust set of stimuli to manipulate cell signaling pathways during tissue formation.

Summary: In this study, gelatin methacrylate (GelMA)/alginate hydrogels were optimized for bioprinting three-dimensional (3D) smooth muscle cell (SMC) constructs. The group with the highest concentrations of GelMA and alginate exhibited the highest viscosity and stability, supporting high cell viability, proliferation, and differentiation towards a contractile SMC phenotype. The results suggest that adjusting the composition of GelMA/alginate hydrogels is an effective means of controlling the SMC phenotype and provides a promising approach for studying smooth muscle adaptation and therapies for urethral strictures.

Summary: This study aimed to test the hypothesis that there would be no difference in radiographic outcome between maxillary sinus floor augmentation (MSFA) with allogeneic adipose tissue-derived stem cells (ASCs) seeded on depro-teinized bovine bone mineral (DBBM) and excipient on DBBM. The results showed that the GV was larger in the test group at one month but larger in the control group at four months. BD increased with both treatments, and the control group had higher BD at four months. The study concluded that allogeneic ASCs seeded on DBBM with MSFA did not improve the radiographic outcome compared with DBBM alone.

Summary: Additive manufacturing technologies have revolutionized tissue engineering by enabling the fabrication of complex tissues with intricate geometries. This review discusses recent advances in tissue engineering fabrication methods, with a focus on hierarchically organized anisotropic tissues. The importance of considering anatomical structure and function in the design process is emphasized, along with the factors influencing fabrication strategy and the advantages and limitations of different methods.

Summary: Excessive skin scarring affects a large number of patients worldwide, and an effective treatment has yet to be found. This study demonstrates the potential of ultrasound for scar reduction by developing a device based on printable piezoelectric material. The device was used to treat human fibroblasts with ultrasound, resulting in a significant reduction in fibroblast growth and extracellular matrix deposition. The overall results suggest that ultrasound treatment could be a beneficial therapy for scar reduction.

Summary: In this study, the effects of cyclic mechanical stimulation on smooth muscle cell maturation were investigated using three-dimensional constructs. The results showed that methacrylate-modified surfaces supported stable adhesion of the 3D constructs and facilitated cyclic mechanical stimulation, resulting in increased expression of contractile markers. These effects were mediated by activation of the p38 MAPK pathway. These findings provide valuable insights into the role of mechanical signaling in maintaining the contractile phenotype of bladder smooth muscle cells and have important implications for future treatments of LUT diseases.

Summary: Stem cells are influenced by biochemical and biophysical cues from the extracellular matrix and neighboring cells. Biomechanical forces play a crucial role in regulating stem cell behavior and fate through mechanotransduction. Recent studies have highlighted the importance of biomechanical signals in tissue regeneration and shown the existence of precise control mechanisms in stem cell niches.

Summary: In silico medicine refers to the use of computational modelling and simulation to study, diagnose, treat or prevent diseases. Although significant progress has been made in using CM&S in clinical applications, there is a need to understand the awareness and usage of CM&S among clinicians in order to identify barriers and opportunities for its future. This study aimed to capture the state of CM&S in clinics through a survey of the clinical community.
