An in vivo imaging protocol to monitor primary sensory axons following dorsal root crush is described. The procedures utilize wide-field fluorescence microscopy and thy1-YFP transgenic mice, and permit repeated imaging of axon regeneration over 4 cm in the PNS and axon interactions with the interface of the CNS.

This video demonstrates a technique for isolating and culturing dorsal root ganglia (DRG) cells from the rat spinal column. DRGs excised from the spinal column are treated with enzymes and mechanically dissociated to obtain a single-cell suspension. The cells are cultured in a medium containing inhibitors and growth factors that limit glial cell proliferation and promote neuronal growth, respectively.

Co-culturing of a Dorsal Root Ganglion Explant with Schwann Cells for Neuron Myelination

2025
This video demonstrates the coculturing model of a dorsal root ganglion explant and Schwann cells. In coculture conditions, ascorbic acid promotes the differentiation of Schwann cells into myelinating forms. Myelinating Schwann cells wrap the axons multiple times to create a myelin sheath, which is essential for nerve function.
FAQs
Their movement toward the dorsal side links cell migration with the spatial organization of neighboring embryonic tissues. Because the cells remain associated with overlying tissue while relocating, researchers can examine how coordinated movements help position developmental structures. This makes them useful for studying how early tissue rearrangements establish the conditions needed for later body organization.
Ciliary motion produces directional fluid flow within Kupffer’s vesicle, providing a physical signal associated with left-right patterning. This process helps explain how embryos establish asymmetry between their two sides and ultimately position organs. Disruptions in cilia function or coordinated movement can therefore be investigated as possible contributors to abnormal laterality.
These cells provide a model for examining several connected processes: directed cell migration, organization of embryonic tissues, cilia-dependent signaling, and the transition from transient embryonic populations to later developmental outcomes. Studying these processes together helps researchers relate cellular behavior during gastrulation to broader questions about how body patterning is established.
Live imaging follows these cells during embryonic development rather than examining only fixed stages. It can show their movement toward the dorsal region, their continued association with overlying tissue, and their relationship to the developing Kupffer’s vesicle. This time-resolved view helps distinguish cell movements and structural changes that occur sequentially during gastrulation.
Cell tracing identifies where dorsal forerunner cells move and how their developmental position relates to nearby tissues and later structures. By following labeled cells through embryonic stages, researchers can connect early migration patterns with the formation of Kupffer’s vesicle and assess how transient cells contribute to developmental organization without relying only on endpoint observations.
Genetic manipulation allows researchers to alter developmental factors and then examine consequences for dorsal forerunner cells, Kupffer’s vesicle, ciliary function, or body asymmetry. Comparing altered embryos with normal development can reveal relationships between cellular mechanisms and outcomes such as disrupted fluid flow or abnormal organ placement, helping identify pathways involved in laterality.
Their connection to Kupffer’s vesicle and left-right patterning makes them especially relevant to studies of laterality defects. Researchers can combine live imaging, cell tracing, and genetic manipulation to investigate where development diverges from the normal sequence. The zebrafish system therefore links observable embryonic cell behavior with questions about the developmental origins of abnormal body asymmetry.
