Embryo Transfer Into Rabbit: A Procedure for Laparoscopy-Guided Transfer of Embryos Into Oviduct of Ovulating Recipient Female Rabbit Model
0 Views •
2025
This video describes the technique of transferring embryos into the oviduct of a recipient female rabbit via Laparoscopy. It allows embryo remodeling in rabbits during its migration through the oviduct, eventually helping in successful implantation. This technique can also be used for stored embryos with good efficiency.

Pancreatic Islets Isolation through Collagenase Perfusion: An Enzymatic Method to Isolate Pancreatic Islet Cells
0 Views •
2023
Pancreatic islets, also called the Islets of Langerhans, are a cluster of endocrine cells which produces hormones for glucose regulation and other important biological functions. This protocol explains a method for isolating pancreatic islets by first perfusing collagenase via Ampulla of Vater to digest the exocrine pancreatic tissue and a simplified density gradient centrifugation to purify the islets from mice.

The microinjection of mouse oocytes is commonly used for both classic transgenesis (i.e., the random integration of transgenes) and CRISPR-mediated gene targeting. This protocol reviews the latest developments in microinjection, with a particular emphasis on quality control and genotyping strategies.

Balance and Coordination Testing

Balance and coordination are critical components involved in the control of movement. Many sensory receptors and neural processing units are required to help individuals maintain balance while performing various activities. Deficits in balance and coordination occur in patients suffering from movement disorders or due to aging. Therefore, scientists are trying to understand the pathophysiology behind these conditions. One way to do that is by using rodent models and testing them on behavioral...

We explored a tubal cytologic method by sampling the fallopian tube directly post-surgical excision as a tool of ovarian cancer early detection. Here, we present a protocol to collect fallopian tube cells from freshly received surgical specimens.
FAQs
In semicircular canals, the ampulla houses sensory hair cells that respond to fluid movement produced by head rotation. That movement is converted into neural signals, linking a mechanical event in the canal to information processed by the nervous system. This makes the structure useful for studying how specialized cells detect motion and how anatomy supports sensory transduction.
The enlarged passage in the fallopian tube is important because it provides room for sperm and oocyte to meet. Its contribution is therefore not simply storage; the increased lumen supports a reproductive encounter within the tube. Examining this region helps connect local anatomy with the spatial requirements of reproduction and the movement of reproductive cells.
An ampulla cannot be assigned one universal function across the body. In semicircular canals, its key role is sensory signaling; in the fallopian tube, it supports interaction between reproductive cells; in the vas deferens and rectum, expansion relates to accommodating and moving contents. Comparison therefore requires considering both location and the material or signal involved.
In the vas deferens and rectum, enlargement is associated with accommodating and moving contents. That relationship illustrates how shape can influence transport in biological tubes: a locally expanded segment may provide space for material while participating in its passage. These examples place ampullae within the broader biology of ducts, lumens, and content movement.
A useful comparative approach begins by locating the ampulla, identifying whether it contains moving fluid, reproductive contents, or sensory hair cells, and then matching its shape to its role. Researchers can compare the fallopian tube, semicircular canals, vas deferens, and rectum to distinguish transport, reproductive, and sensory functions without treating all ampullae as equivalent.
Studying ampullae helps biology link anatomical form to different kinds of function. The same general enlargement can be examined through reproductive cell encounters, movement of fluid during head rotation, or accommodation and movement of duct or rectal contents. This cross-system perspective supports comparisons among reproduction, digestion, fluid dynamics, and sensory biology rather than isolating anatomy from physiology.
