Stem cell research firm Celprogen Inc. has been working on something quite exciting for some time now, which has remained largely under the radar until very recently. The California-based company announced it has successfully 3D printed a human brain organelle using brain stem cells. The bioprinted brain could have applications in studying neurological diseases.

More than just announcing the bioprinted brain organelle, Celprogen has also used the brain to study the “role of Microglia activation and deactivation in neurological diseases.” Through this research and experimentation, the company says it has identified and characterized 11 lead compounds that could be potential drug candidates for diseases such as Alzheimer’s, Parkinson’s and Glioblastoma.
