The extracellular matrix (ECM) is a heterogeneous, connective network composed of fibrous glycoproteins that coordinate in vivo to provide the physical scaffolding, mechanical stability, and biochemical cues necessary for tissue morphogenesis and homeostasis. This review highlights some of the recently raised aspects of the roles of the ECM as related to the fields of biophysics and biomedical engineering. Fundamental aspects of focus include the role of the ECM as a basic cellular structure, for novel spontaneous network formation, as an ideal scaffold in tissue engineering, and its essential contribution to cell sheet technology. As these technologies move from the laboratory to clinical practice, they are bound to shape the vast field of tissue engineering for medical transplantations.

Stem-cell-derived 'synthetic' embryo models represent a revolutionary avenue in developmental biology, offering unprecedented insights into embryogenesis and tissue formation. However, the majority of current research on embryo models resides predominantly in the engineering construction phase, with limited substantive applications. This review explores the utilization of these embryo models and their applications in deciphering fundamental developmental processes.

Fabrication of macroporous scaffolds with favorable mechanical and biological properties based on natural polysaccharides embedding inorganic components has emerged as a promising alternative for bone regeneration. We hypothesized that partially demineralized chitin containing natural calcium phosphate with suitable mechanical strength as the inorganic component is more favorable for this purpose than commonly used nano-hydroxyapatite (nHA). Therefore, a macroporous cryogel scaffold composed of gelatin (G), nanofibrillated cellulose (NFC), and partially demineralized chitin (PDCh), chemically crosslinked with oxidized dextran (ODex), was developed in this study.

The success of biomaterial applications in medicine, particularly in tissue engineering, relies on achieving a balance between promoting tissue regeneration and controlling the immune response. Due to its natural origin, high biocompatibility, and versatility, chitosan has emerged as a promising biomaterial especially for immunomodulation purposes. Immunomodulation, refers to the deliberate alteration of the immune system's activity to achieve a desired therapeutic effect either by enhancing or suppressing the function of specific immune cells, signaling pathways, or cytokine production.

Tissue engineering constantly needs innovative and biocompatible materials, and peptide-based materials seem very inspiring. Here we developed two new self-assembling peptides based on RADA16-I and RGD peptides and studied their potential in forming nanofibers under various conditions using all-atom and coarse-grained molecular dynamics simulation methods. First, a double-tailed RGD (dtRGD) peptide was designed by attaching two RADA16-I tails to an RGD-containing loop in which two disulfide bonds stabilized the loop integrity.

The urethra is a fibromuscular tube that transports urine from the bladder to the exterior of the body. Congenital disorders and urethral wall strictures caused by traumatic injuries, infections, iatrogenic injuries, and tumor removals can impair urethral function. This research aimed to create a 3D printed scaffold of the urethra using casting and 3D printing techniques, and then the constructed scaffolds were characterized.
