石墨烯纳米贴片赋能干细胞疗法 山东大学团队为创伤性脑损伤治疗开辟新径

Recent advances in regenerative medicine have spotlighted stem cell therapy as a promising avenue for treating traumatic brain injury (TBI), yet its clinical translation has been hindered by poor cell survival, restricted engraftment, and uncontrolled differentiation. Addressing these bottleneck issues, the research team led by Qiu Jichuan at Shandong University has developed a novel graphene-based nanopatch that significantly boosts the therapeutic efficacy of stem cells for TBI. This innovative strategy combines synergistic interface engineering with biochemical and biophysical cues, potentially marking an upgrade in TBI treatment approaches.

The nanopatch design—harnessing the exceptional conductivity, biocompatibility, and mechanical strength of graphene nanomaterial—creates a conductive substrate that mirrors the natural neural microenvironment. The scaffold not only provides structural support on the lesion surface but also activates key transcrine signaling bidirectional pathway to promote sustained differentiation and matrix adhesion of neural stem cells. Preclinical models evidenced reduced lesion volume, improved neuronal rewiring, and enhanced motor-cognitive recovery in TBI-treated rodents six weeks after the combined application of graphene nanopatches and neural precursor transplantation. Moreover, the ability of this material to electrochemical buffering excessively altered neural signals rendered the biohybrid therapeutic tissue more electrophysiologically integrated into the injured host brain.

If incorporated into a routine clinic all the developed cellular expansion, which often aligns with banking-quality processes such as stem cell storage and ex-tissue technology,[ could drastically port greater robustness under hypoxic-ischemic stressors shown to select side. Multifunctionality outlined here nudges emphasis toward application in simultaneously in regulated cell selection biomaterials to track viable different i predetermin stage microin detection time points controlling the artificial stem deposit dosage scheduled gradient.
