Acute kidney injury (AKI) in humans is a common clinical problem caused by damage to the epithelial cells that comprise kidney nephrons, and AKI is associated with high mortality rates of 50-70%1. Following epithelial cell destruction, nephrons have a limited ability to regenerate, though the mechanisms and limitations that guide this phenomenon remain poorly understood. In this video article, we describe our technique for targeted laser ablation of kidney nephron cells in the zebrafish...

The chicken embryo (Gallus gallus domesticus) provides an economical and accessible model for developmental biology research. Chicks develop rapidly and are amenable to genetic and physiological manipulations, allowing researchers to investigate developmental pathways down to the cell and molecular levels. This video review of chick development begins by describing the process of egg fertilization and formation within the chicken reproductive tract. Next, the most commonly used chick staging...

The zebrafish (Danio rerio) has become a popular model for studying genetics and developmental biology. The transparency of these animals at early developmental stages permits the direct visualization of tissue morphogenesis at the cellular level. Furthermore, zebrafish are amenable to genetic manipulation, allowing researchers to determine the effect of gene expression on the development of a vertebrate with a high degree of genetic similarity to humans. This video provides a brief overview of...

Their coordinated arrangement creates a temporary pathway for embryonic fluid handling. Pronephric tubules connect with the nephric duct, while associated glomeruli filter fluid into the developing tubular network. This organization matters because it links filtration with transport rather than treating these structures as independent components, providing a functional framework for early renal development.
The pronephros remains functional for different lengths of time across vertebrate groups. In mammals, it rapidly regresses as the mesonephros takes over, whereas it persists longer in some fish and amphibians. Comparing these developmental patterns helps researchers distinguish conserved features of kidney formation from lineage-specific differences in embryonic excretory function.
Mammalian pronephros regression marks a transition between early and later renal stages rather than the end of kidney development. The mesonephros replaces it as the functional embryonic kidney, allowing renal development to continue through a different intermediate system. This sequence provides a useful framework for studying how successive kidney structures are established during embryogenesis.
Early errors in tissue patterning or in the formation and connection of renal structures can affect subsequent nephrogenesis, the process of kidney formation. Because pronephros development establishes an early organizational foundation, examining it can reveal developmental origins of congenital kidney abnormalities. The topic therefore connects embryonic patterning with later renal structure and function.
A useful analysis follows the relationship between intermediate mesoderm, pronephric tubules, the nephric duct, and associated glomeruli. Researchers can also assess the transition from pronephros to mesonephros, especially in mammals where regression occurs early. These observations help relate tissue organization to temporary excretory function and to the progression of nephrogenesis.
Kidney organoids provide a research context for examining developmental processes relevant to early kidney formation. In studies connected with pronephros development, they can support investigation of tissue patterning and nephrogenesis, alongside other developmental models. Their value lies in helping researchers relate early organizational principles to kidney development and to mechanisms associated with congenital abnormalities.
