Here, we describe a platform that allows noninvasive in vivo imaging of liver spheroids engrafted in the anterior chamber of the mouse eye. The workflow spans from generating spheroids from primary liver cells to transplantation into the mouse eye and in vivo imaging at cellular resolution by confocal microscopy.

This video describes the protocol for grafting human pancreatic islets into the anterior chamber of the mouse’s eye to monitor revascularization of human islet grafts in vivo. It also helps to understand the contribution of recipient versus donor cells in promoting the encapsulation and vascularization of the graft.

The goal of the protocol is to show longitudinal intravital real-time tracking of thymocytes by laser scanning microscopy in thymic implants in the anterior chamber of the mouse eye. The transparency of the cornea and vascularization of the graft allows for continuously recording progenitor cell recruitment and mature T-cell egress.

Nuclear Stability

Protons and neutrons, collectively called nucleons, are packed together tightly in a nucleus. With a radius of about 10−15 meters, a nucleus is quite small compared to the radius of the entire atom, which is about 10−10 meters. Nuclei are extremely dense compared to bulk matter, averaging 1.8 × 1014 grams per cubic centimeter. If the earth’s density were equal to the average nuclear density, the earth’s radius would be only about 200 meters. To hold positively charged protons together in the...
FAQs
Pressure regulation depends on the relationship between aqueous humor formation, movement through the anterior chamber, and exit through the trabecular meshwork and Schlemm’s canal. If drainage does not adequately accommodate fluid production, pressure and chamber configuration can change; if fluid escapes through a compromised boundary, the chamber may lose appropriate support. These relationships make fluid balance central to ocular stability.
A change in chamber depth is clinically meaningful because it can reflect altered pressure, disrupted fluid movement, or loss of containment. Such changes may disturb the relationships among the cornea, iris, and lens and can increase the possibility of tissue damage. Depth therefore serves as an observable indicator of whether the anterior segment remains mechanically supported.
Secure ocular boundaries limit aqueous humor loss and help retain the chamber’s intended configuration. Their importance becomes especially apparent when trauma or an operative opening disrupts containment. In those settings, stability depends not only on internal production and drainage but also on preventing uncontrolled fluid loss. Boundary integrity must therefore be considered alongside pressure and chamber depth.
In glaucoma evaluation, clinicians consider chamber depth and pressure together with the underlying aqueous humor pathway. Findings that suggest impaired drainage can indicate that fluid dynamics are contributing to ocular risk. The assessment connects anatomical configuration with pressure regulation and helps identify circumstances in which altered fluid handling may contribute to tissue damage.
Trauma can compromise ocular boundaries, disturb chamber configuration, or alter fluid behavior. Evaluation therefore focuses on whether fluid containment and the relationships among the cornea, iris, and lens remain preserved. Recognizing these changes is important because loss of stability can contribute to tissue damage and may guide management intended to restore a safer anatomical and pressure environment.
Cataract procedures can challenge the chamber’s normal configuration and fluid containment. Preserving appropriate depth and pressure helps maintain the expected relationships of the cornea, iris, and lens and reduces the likelihood of postoperative complications. For this reason, stability is a key surgical consideration during and after the procedure, rather than an issue relevant only to glaucoma assessment.
