Temporal Ordering of Dynamic Expression Data from Detailed Spatial Expression Maps

The segmentation clock drives oscillatory gene expression across the pre-somitic mesoderm (PSM). Dynamic Notch activity is key to this process. We use imaging and computational analyses to extract temporal dynamics from spatial expression data to demonstrate that Delta ligand and Notch receptor expression oscillate in the vertebrate PSM.

University of Notre Dame, IN The Guide for the Care and Use of Laboratory Animals1 dictates that rodent survival surgery be performed aseptically. Aseptic technique utilizes specific practices that minimize the contamination of the surgical site, including patient preparation, surgeon preparation, sterilization of instruments and other supplies, and the use of a clean and controlled environment.

Animal models are frequently utilized to study cancer metastasis to bone. In this protocol we will describe two common methods of tumor inoculation for bone metastasis studies and briefly describe some of the analyses utilized to monitor and quantify these models.
FAQs
High-speed drilling allows surgeons to work through the dense temporal bone and create a controlled route to abnormal tissue or deeper skull-base regions. Because the bone surrounds delicate anatomy, drilling must be precise and continuously guided by the intended clinical goal. This controlled removal helps provide access while limiting unnecessary disruption of nearby ear, nerve, and vascular structures.
The approach is tailored to both the patient’s anatomy and the condition being treated. A procedure for chronic ear disease or cholesteatoma may emphasize removal of abnormal tissue and disease control, whereas surgery for a tumor, trauma, or cerebrospinal fluid leak may require a different route to reach the affected area. This customization supports safer access and structure preservation.
Temporal bone procedures require attention to the ear, facial nerve, inner ear, and major blood vessels because these structures lie within or adjacent to the operative field. Identifying them during the operation helps surgeons remove targeted abnormal tissue while protecting hearing, facial movement, and other critical functions. Their close anatomical relationship explains why the surgery demands detailed planning and precision.
The operative objective determines how much abnormal tissue must be removed and which nearby structures require particular protection. Treating infection or cholesteatoma centers on controlling disease, while surgery involving tumors, trauma, or cerebrospinal fluid leaks may prioritize access to a specific lesion or defect. Surgeons therefore adapt the extent and route of dissection rather than applying one uniform technique.
A typical approach begins with careful planning based on the condition and relevant anatomy. Surgeons then use high-speed drilling to reach the targeted region, identify important structures within the operative field, and remove the abnormal tissue or address the defect. The exact route and extent of work vary, including techniques such as mastoidectomy when appropriate to the clinical goal.
Mastoidectomy is one technique that can be selected when the clinical objective requires access through or treatment of the mastoid portion of the temporal bone. Its use depends on the underlying anatomy and disease process rather than on a single indication. In the broader group of procedures, it may contribute to management of chronic ear disease or cholesteatoma when disease control requires that route.
These procedures may be used for chronic ear disease, cholesteatoma, tumors, trauma, and cerebrospinal fluid leaks. The expected purpose differs by condition: surgery can help control infection, remove abnormal tissue, protect hearing or facial movement, or provide access to a lesion or defect. The range of indications reflects the temporal bone’s relationship to the ear and skull base.
Some lesions extend beyond the immediate ear region or involve structures shared with the skull base, making coordinated care important. Temporal bone surgery can provide access to lesions that require multidisciplinary skull-base management, while the operative plan remains focused on anatomy, disease removal, and preservation of critical structures. This context is especially relevant when tumors or complex defects are involved.
