Background:

  • Traumatic brain injury (TBI) is a significant global health issue with no FDA-approved treatments.
  • Current TBI research models are often complex, expensive, and inaccessible.
  • There's a critical need for advanced, user-friendly TBI research tools.

Purpose of the Study:

  • To develop an accessible, modular, 3D-printed device for inducing TBI-like injuries in vitro.
  • To demonstrate the device's versatility across different cell types and its ability to model repetitive TBI.
  • To provide a high-throughput, animal-free platform for TBI research.

Main Methods:

  • Designed and constructed a modular, 3D-printed device for TBI induction using pressure shock.
  • Applied the device to standard cell-culture tools and various cell types.
  • Evaluated the platform's ability to recapitulate key TBI pathological hallmarks.

Main Results:

  • The 3D-printed device successfully induced TBI-like injuries in vitro.
  • The platform demonstrated efficacy in modeling repetitive TBI and various cell types.
  • Key TBI hallmarks, including cell death and decreased neuronal function, were recapitulated.

Conclusions:

  • The developed 3D-printed TBI induction device offers an accessible and versatile research tool.
  • This platform facilitates high-throughput, in vitro TBI modeling, reducing reliance on animal models.
  • The innovation has the potential to accelerate the development of novel TBI treatments.
