Summary: Research has shown that Ret signaling in kidney development is crucial for maintaining tip cells in the ureteric bud. Cells genetically forced to maintain Ret expression exhibit a tip-seeking behavior and self-organize into dense clusters in organoids. This suggests that Ret-dependent cell behaviors play a significant role in normal branching morphogenesis.

Summary: Developing in vitro models of human kidney tissue using human pluripotent stem cells (hPSCs) is challenging but essential for regenerative nephrology research. This article describes a step-by-step protocol for differentiating hPSCs into three-dimensional ureteric bud (UB) organoids, which exhibit complex morphological development and can differentiate into functional collecting duct tissues. This approach provides a robust and reproducible method for generating UB tissues that can be used to study kidney development, model disease processes, and aid in the engineering of functional kidney tissue.

Summary: Bioprinting is a highly useful tool with immense potential in various scientific and biotechnological fields. In medicine, bioprinting focuses on printing cells and tissues for skin regeneration and the production of viable human organs like hearts, kidneys, and bones. This review presents a chronological overview of the significant advancements in bioprinting technique and its current status through an analysis of 122 selected articles out of 31,603 papers found in SCOPUS, Web of Science, and PubMed databases. The paper concludes by discussing the applications and expectations of bioprinting.

Summary: Distinct progenitors contribute to the nephrons versus the ureteric epithelium during kidney development. The distal nephron segment alone displays significant in vitro plasticity and can adopt a ureteric epithelial tip identity when isolated and cultured in defined conditions. Cultures harboring loss-of-function mutations in PKHD1 recapitulate the cystic phenotype associated with autosomal recessive polycystic kidney disease.

Summary: Tubular structures are crucial for organ functions, and controlling their formation is essential for tissue engineering. We investigated the influence of substrate stiffness on tubulogenesis of mIMCD cells and found the optimal range to be between 277 kPa and 2610 kPa. We also observed that different substrate concentrations are associated with different expression levels of ZO-1 and that agarose generally leads to a greater tube formation rate.

Summary: This review compares branching morphogenesis and its regulation in the lungs and kidneys, discussing the role of signaling pathways, mesenchyme, extracellular matrix, and cytoskeleton as potential determinants of branch position, orientation, and shape. Understanding the determinants of branch and organ shape in different organs may reveal how a highly conserved developmental process can adapt to various structural and functional frameworks.

Summary: This study presents a microfluidic-assisted tissue model of nociception with microvasculature. The neurons and endothelial cells displayed distinct morphologies in the presence of each other. The neurons exhibited an elevated response to capsaicin in the presence of vasculature, and increased TRPV1 receptor expression was observed in the neurons. The platform could also be used to study pain associated with tissue acidosis and pave the way for the development of innervated microphysiological models.

Summary: Collagen XVIII, a component of the extracellular matrix, plays a specific role in renal branching morphogenesis. Different isoforms of collagen XVIII are expressed at different times and locations during renal development. Lack of collagen XVIII or specific isoforms leads to congenital defects in the 3D patterning of the ureteric tree, particularly involving the short isoform. Furthermore, ex vivo data suggests that collagen XVIII is involved in kidney epithelial tree patterning through its N-terminal domains, especially the Thrombospondin-1-like domain common in all isoforms. This indicates the important role of collagen XVIII in matrix-integrin-mediated functions regulating renal development.

Summary: Manglietiastrum sinicum Y.W. Law is a critically endangered species with high ornamental and commercial value. This study optimized the conditions for bud induction, proliferation, and rooting of M. sinicum. The best medium for bud induction was Murashige and Skoog medium supplemented with 0.5 mg/L 6-benzyladenine (BA) and 0.05 mg/L indole-3-butyric acid (IBA). The optimal medium for efficient proliferation and rooting was MSM medium. RAPD and ISSR markers confirmed the genetic uniformity and stability of regenerated plants.

Summary: This scientometric analysis examines the development and use of bioinks for 3D bioprinting in the period from January 2000 to June 2019. The main considerations for bioink applications include cost, availability, practicality, and basic biological factors. Extrusion bioprinting is currently the most popular technique, with bioinks commonly used for generic characterization and cartilage bioprinting applications. Despite advancements in functional bioinks, the field is still in early stages with alginate and gelatin methacryloyl being the most commonly used hydrogels.

Summary: Organoids developed from pluripotent stem cells or adult stem cells are three-dimensional cell cultures that mimic certain biological developmental processes of organs, with promising applications in drug screening, disease modeling, and regenerative repair. The challenges facing organoid construction include breakthroughs in scale size, vascularization, reproducibility, and precise architecture. Bioprinting techniques, with the application of bioinks, have accelerated the process of organoid construction, and a multidisciplinary combination of developmental biology, disease pathology, cell biology, and materials science will help overcome obstacles to further develop real organs.

Summary: Synthetic morphogenesis is a new engineering discipline that genetically engineers cells to create designed shapes and structures. Devices in this field utilize natural shape-generating processes from embryonic development, but artificially manipulate them according to a technologist's preferences. Synthetic morphogenesis enables the construction of two-way interfaces between living organisms and electronic devices, facilitating unprecedented information flow and control.
