2025
This video demonstrates a method to differentiate human neural progenitor cells (NPCs) into neurons. The NPCs are introduced onto an established mouse astrocyte-rat cortical neuron co-culture, promoting NPC differentiation into neurons. The differentiation is confirmed by visualizing the cells under a confocal microscope.

This video demonstrates a method for the in vitro generation of neural progenitor cells (NPCs) from mouse embryonic stem cells (mESCs). The mESCs are cultured in suspension to form embryoid bodies (EBs), which are then guided to differentiate into NPCs via retinoic acid treatment in an adherent culture.

Neural Activity Propagation in an Unfolded Hippocampal Preparation with a Penetrating Micro-electrode Array

We have developed an in vitro unfolded hippocampus which preserves CA1-CA3 array of neurons. Combined with the penetrating micro-electrode array, neural activity can be monitored in both the longitudinal and transverse orientations. This method provides advantages over hippocampal slice preparations as the propagation in the entire hippocampus can be recorded simultaneously.
FAQs
Accurate alignment places the damaged nerve ends in a position that preserves continuity across the repair site. Maintaining fascicular orientation helps regenerating axons encounter the appropriate pathway as they cross the coaptation area. This precision supports later reinnervation of target muscles or sensory regions and makes alignment a central determinant of the repair’s potential functional value.
Minimizing tension helps maintain stable contact between the repaired nerve ends while axons regenerate across the coaptation site. It works together with accurate positioning rather than replacing it: a low-tension repair must still preserve fascicular orientation and continuity. These combined conditions support the biological process needed for recovery of motor or sensory function.
Magnification allows surgeons to inspect and align small nerve structures with greater precision. Fine sutures or other adjuncts then help maintain the selected relationship between the nerve ends during repair. These tools do not independently ensure recovery, but they support the technical goals of accurate orientation, minimal tension, and a continuous pathway for regenerating axons.
When regenerating axons cross the repair site and reach their intended targets, they may support reinnervation of muscles or sensory regions. The expected outcome therefore extends beyond restoring anatomical continuity: it includes the possibility of recovering useful function. Long-term results remain an area of research, particularly as investigators evaluate repair precision and materials.
The procedure centers on carefully preparing and positioning the damaged nerve ends, viewing the repair with magnification, and securing the connection with fine sutures or other adjuncts. Throughout the repair, surgeons aim to minimize tension and preserve fascicular orientation. These steps create conditions that allow regenerating axons to cross the repair site.
Clinical use may arise after traumatic nerve damage, during tumor removal, or as part of a reconstructive procedure. In each setting, the technique addresses a disrupted nerve pathway and seeks to support later functional recovery. The relevant target may be motor, sensory, or both, depending on whether axons ultimately reinnervate muscles or sensory regions.
Assessment focuses on whether the repair supports axonal passage and subsequent reinnervation of target muscles or sensory regions. Research continues to examine how improved repair materials and greater procedural precision might influence long-term functional outcomes. This work connects microsurgical technique with broader efforts to make peripheral nerve repair more reliable after injury or surgical disruption.
