Mouse tissue was collected in accordance with the guidelines and regulations set forth by the University of Iowa Institutional Animal Care and Use Committee (ACURF 0804066).

In this video, we demonstrate a method to combine four techniques in order to maximize data collection and cohesiveness by correlating data within a given animal (figure 3). This approach will reduce the amount of breeding and thus time needed to obtain publishable data while improving information about co-localization and correlative effects of mutants. Although embryonic mice were utilized in this video, adult mouse as well as other animals such as chicken, xenopus, and zebrafish can be analyzed using these techniques as well. When using other species proteinase k digestion may need to be altered. Here we use different fluorescing NeuroVue dyes to specifically label up to three neuronal populations of interest. The benefit of these dyes is that they can be used in mutant mice, which may be problematic when relying solely on immunohistochemistry that may or may not be affected by the mutations to be analyzed, and they label neurons retrogradely and anterogradely 5. A recent study has also increased the number of neuron populations that can be labeled simultaneously to six 2. After, the lipophilic dye tracing the same tissue of interest can then be analyzed using in situ hybridization, for analysis of gene transcription and can be subsequently analyzed using immunohistochemistry for protein distribution. The latter analysis can be supplemented by detailed histology which can add to the phenotype characterization 6. This multifactorial analysis has the potential to gain new insights through correlative analysis within the same animal that may otherwise be improbable or at least in need of more extensive protocols and mouse breeding.

combining lipophilic dye, in situ hybridization, immunohistochemistry, and histology

Going beyond single gene function to cut deeper into gene regulatory networks requires multiple mutations combined in a single animal. Such analysis of two or more genes needs to be complemented with in situ hybridization of other genes, or immunohistochemistry of their proteins, both in whole mounted developing organs or sections for detailed resolution of the cellular and tissue expression alterations. Combining multiple gene alterations requires the use of cre or flipase to conditionally delete genes and avoid embryonic lethality. Required breeding schemes dramatically enhance effort and cost proportional to the number of genes mutated, with an outcome of very few animals with the full repertoire of genetic modifications desired. Amortizing the vast amount of effort and time to obtain these few precious specimens that are carrying multiple mutations necessitates tissue optimization. Moreover, investigating a single animal with multiple techniques makes it easier to correlate gene deletion defects with expression profiles. We have developed a technique to obtain a more thorough analysis of a given animal; with the ability to analyze several different histologically recognizable structures as well as gene and protein expression all from the same specimen in both whole mounted organs and sections. Although mice have been utilized to demonstrate the effectiveness of this technique it can be applied to a wide array of animals. To do this we combine lipophilic dye tracing, whole mount in situ hybridization, immunohistochemistry, and histology to extract the maximal possible amount of data.
