This manuscript describes a method to isolate the developing metanephric anlagen from the mouse embryo and to culture the organ rudiments. This method is a standard technique, as developed by Grobstein8 and Sax&#233;n9,10, and was adapted and modified by many others11,12. The success of the method depends mainly on the duration of the dissection, as explant survival and inductive p...

The mammalian kidney is derived from two primordial structures with mesodermal origin: the tubular epithelial ureteric bud and the metanephric mesenchyme. During nephrogenesis, the ureteric bud invades the metanephric mesenchyme and branches to form the collecting system. The metanephric mesenchyme gives rise to the epithelial elements of the nephrons. These processes occur in a precisely timed and spatially coordinated manner and are initiated by reciprocal inductive mechanisms. Both tissue components communicate and affect the other's cell morphogenesis. 
In the 1920s, it was Boyden who performed the in vivo obstruction of the mesonephric duct in chicken, providing the first indication of inductive interactions as separated nephric blastema fail to differentiate1. At about the same time, the first successful attempts to culture chicken nephric rudiments in a hanging drop were published. Subsequently, the organ culture was developed to study tissue interactions in mammalian organogenesis. In the 1950s, Grobstein developed a technique in which metanephric rudiments could be cultured on a filter. This technique was modified by Sax&#233;n, who placed the filter on a Trowell-type screen in a culture dish1. Over the years, many modifications and applications for organ culture have emerged. The method described here is based on Sax&#233;n's technique but is simplified, as the filters float free on the medium and the diameter of the culture well only slightly exceeds the diameter of the filter, limiting unwanted movement of the filter.
Whole-organ culture is a classical, cheap, and simple but powerful tool to investigate cellular processes and intercellular communication during organogenesis. Organ culture allows for treatment with biological agents, such as growth factors, antibodies, antisense oligonucleotides, viruses, and peptides, as well as with pharmaceutical compounds and other chemicals. Also, gene function may be studied using explants derived from genetically modified mice or using inducible gene inactivation technology, such as the Cre-loxP system. This allows for the study of genetic mutations that cause embryonic lethality prior to the development of the kidney. Organ culture can also be combined with fluorescent tagging for gene function or lineage tracing and modern imaging techniques, which enable real-time monitoring of cell behavior2.
In the specific example provided here, the effect of EphrinB2-activated Eph-receptor signaling on the branching morphology of the ureteric bud was investigated. The morphology of the EphA4/EphB2 double-knockout mice suggested several severe defects in kidney development, which were detectable as early as embryonic day 11 (E11) and involved the ureteric bud, the ureter, and the common nephric duct3. Signaling via Eph receptors requires the clustering of the ligand-receptor dimer4. To over-activate Eph signaling, the kidney rudiments from E11.5 mouse embryos were cultured in the presence of clustered recombinant EphrinB2-Fc. EphrinB2 is a known ligand for the EphA4 receptor, which is expressed in the ureteric bud tips3.

dissection and culture of mouse embryonic kidney

The goal of this protocol is to describe a method for the dissection, isolation, and culture of mouse metanephric rudiments. 
During mammalian kidney development, the two progenitor tissues, the ureteric bud and the metanephric mesenchyme, communicate and reciprocally induce cellular mechanisms to eventually form the collecting system and the nephrons of the kidney. As mammalian embryos grow intrauterine and therefore are inaccessible to the observer, an organ culture has been developed. With this method, it is possible to study epithelial-mesenchymal interactions and cellular behavior during kidney organogenesis. Furthermore, the origin of congenital kidney and urogenital tract malformations can be investigated. After careful dissection, the metanephric rudiments are transferred onto a filter that floats on culture medium and can be kept in a cell culture incubator for several days. However, one must be aware that the conditions are artificial and could influence the metabolism in the tissue. Also, the penetration of test substances could be limited due to the extracellular matrix and basal membrane present in the explant.
One main advantage of organ culture is that the experimenter can gain direct access to the organ. This technology is cheap, simple, and allows a large number of modifications, such as the addition of biologically active substances, the study of genetic variants, and the application of advanced imaging techniques.

Metanephric kidney anlagen were derived from pregnant Black-6 inbred mice at E11.5 and were cultured. After 3 days, the ureteric bud had branched up to 5 times, resulting in a ramification of the initially T-shaped ureteric bud. Each explant was photographed, and the numbers of segments and endpoints were quantified to determine the branching generations and to calculate the number of endpoints per branch (Figure 1). ImageJ (rd generation; the 4th ge...
