Sea lamprey lose the gall bladder and bile ducts during metamorphosis, a process similar to human biliary atresia. A new fixation and clarification method (CLARITY) was modified to visualize the entire biliary tree using laser scanning confocal microscopy. This method provides a powerful tool to study biliary degeneration.

The C. elegans excretory canal is a unique single-cell model for the visual in vivo analysis of de novo polarized membrane biogenesis. This protocol describes a combination of standard genetic/RNAi and imaging approaches, adaptable for the identification and characterization of molecules directing unicellular tubulogenesis, and apical membrane and lumen biogenesis.

Acute brain trauma is a severe injury that has no adequate treatment to date. Multiphoton microscopy allows studying longitudinally the process of acute brain trauma development and probing therapeutical strategies in rodents. Two models of acute brain trauma studied with in vivo two-photon imaging of brain are demonstrated in this protocol.
FAQs
In bone, the canalicular network helps osteocytes remain viable by linking their lacunae to surrounding fluid. Osteocyte processes occupy these narrow passages, positioning the cells within tissue where direct access is limited. Exchange through the fluid-filled network supports movement of nutrients and waste, while the connected environment also allows information to travel across the tissue.
Mechanical and biochemical signals can move through the bone canalicular environment, giving osteocytes a way to respond to local conditions and coordinate tissue behavior. This matters because osteocytes are embedded within dense bone rather than exposed at a free surface. Canaliculi therefore provide a route for sensing and communication in addition to material exchange.
Their roles reflect the functions of the tissues in which they occur. In bone, canaliculi connect lacunae and support osteocyte processes, nutrient and waste exchange, and signal transmission. In the liver, bile canaliculi collect secretions between neighboring hepatocytes. Comparing them shows how similarly narrow pathways can support different forms of tissue organization and transport.
Osteocyte processes occupy the narrow canaliculi that radiate from lacunae. Their presence extends the cell's interface through the surrounding bone and places the osteocyte within the fluid-filled network. This arrangement supports contact with pathways for nutrient and waste movement and helps connect cellular activity with mechanical and biochemical signals in the tissue.
Studying canaliculi helps explain how cells remain viable when tissue structure limits direct access to their surroundings. It can also clarify how nutrients and waste are exchanged, how cells coordinate responses, and how signals move through tissue. These insights connect microscopic architecture with the maintenance of broader tissue function.
Bile canaliculi are relevant because they collect secretions between neighboring hepatocytes, linking cellular activity with an organized pathway through liver tissue. Examining this arrangement helps place hepatocyte secretion within the structure of the organ. It also illustrates how specialized microscopic channels can support tissue-level function without serving the same role as bone canaliculi.
