Summary: Damage or loss of bone tissue is a major issue affecting human well-being, and tissue engineering is used to recover and regenerate bone fractures and damage. Polymer biomaterials are the most commonly required materials for synthetic bone scaffolds due to their suitable mechanical properties and degradation rates. Synthetic polymers offer advantages in bone replacement because they can be designed and changed easily, and their biocompatibility has been widely accepted in tissue engineering. This article updates on materials and application usage of scaffolds in bone tissue engineering for hard tissue regeneration.

Summary: In this study, we successfully created a three-dimensional bioprinted artificial larynx using rabbit's chondrocyte-laden gelatin methacryloyl (GelMA)/glycidyl-methacrylated hyaluronic acid (GMHA) hybrid bioink. We incorporated a polycaprolactone (PCL) outer framework with pores to provide structural strength and a suitable microenvironment for the printed cells. Our novel fluidics supply (FS) system improved cell viability during the printing process, leading to the generation of a large-scale cell-laden artificial laryngeal framework. Animal studies confirmed the functionality of the transplanted 3D bio-larynx, offering potential for clinical applications in laryngectomy patients.

Summary: Polyhydroxyalkanoates (PHAs) have great potential in biomedical applications, especially tissue engineering, due to their superior biocompatibility and biodegradability. Textile fiber-based tissue engineering scaffolds can mimic the properties of native tissues, and combining them with PHAs can improve performance. However, the complex crystallization behavior of PHAs and the resulting spinning procedures are still challenging. Additionally, the biomedical application of PHAs is hindered by insufficient polymer purity.

Summary: The advent of supramolecular biopolymers has brought promising opportunities for tissue engineering, due to their tailorability, absence of toxic byproducts, and better mimicry of extracellular matrix nanotopography and mechanical properties. However, there is still a lack of understanding of their properties at meso- and macroscales. In this review, molecular modeling approaches are discussed, highlighting their advantages and limitations in representing and transferring the properties of supramolecular biopolymers.

Summary: The development of new scaffolds and materials for tissue engineering is a wide and open realm of material science. Among solutions, the use of biopolymers represents a particularly interesting area of study due to their great chemical complexity that enables creation of specific molecular architectures. However, biopolymers do not exhibit the properties required for direct application in tissue repair-such as mechanical and electrical properties-but they do show very attractive chemical functionalities which are difficult to produce through in vitro synthesis. The combination of biopolymers with nanostructured carbon fillers could represent a robust solution to enhance composite properties, producing composites with new and unique features, particularly relating to electronic conduction. In this paper, we provide a review of the field of carbonaceous nanostructure-containing biopolymer composites, limiting our investigation to tissue-engineering applications, and providing a complete overview of the recent and most outstanding achievements.

Summary: The study presents a Microwell Flow Device (MFD) that generates in-well laminar flow around 3D tissues to study cancer progression and therapeutic development. The results show that the spheroids cultured in the MFD exhibit improved cell growth, reduced necrotic core formation, enhanced structural integrity, and downregulated expression of cell stress genes. The flow-cultured spheroids also exhibit an improved sensitivity to chemotherapy and greater transcriptional response. This platform enables study into hypoxia modulation, cancer metabolism, and drug screening within pathophysiological conditions.

Summary: This study aims to identify two critical components required for pharmaceutical cleaning verification when an FTIR is used: the number of scans required per hard-to-clean location, and the limit of quantification (LOQ) of the FTIR instrument when measuring surface contamination. The current practice in pharmaceutical manufacturing does not require multiple samples, but this study suggests that collecting a sufficient number of samples is necessary to ensure measurement results are close to the true value. Furthermore, the study addresses the complexity in calculating the LOQ when dealing with complex experimental data.
