According to the World Health Organization, fifteen million people die of ischemic stroke worldwide each year.[1] The brain is an organ that has no capability to regenerate, unlike many other organs of our body. An injury to this organ normally till date remains untreatable to conditions with no return. A traumatic brain injury (TBI) triggers a reparative process identified as release of a set of molecules called damage-associated molecular patterns (DAMPs). The effort by our body to repair the damage is natural, yet when the injury is larger than the normal repair abilities, an inflammatory response ensues that leads to neurodegeneration and thus permanent damage.[2] Stem cells are undifferentiated cell types that have the potential to populate to form cells like themselves and differentiate into various types of cells under various hormonal influences.[3] Various thermally controlled immortalised neuronal progenitors such as RMNE6 have been developed and show high promise in ischemic therapy. Systematic studies leading to effective implementation of these new approaches are a very exciting development.

The challenges in the TBI field is one of the toughest problems for stem cell research. Some different types of stem cells such as embryonic stem cells (ESCs), multipotent adult progenitor cells (MPCs), adult neural stem cells (NSCs), and inducible pluripotent stem cells (iPSCs) have been developed. Mesenchymal stem cells (MSCs) and bone marrow stromal cells (BMSCs) are various exogenous stem cell types. The promises of these developments in the TBI field are very encouraging. More work in this direction where cell lines with features suited for proliferation without a tumor-like formation are anticipated.

In this volume, the study by Wu et al.[4] makes a comparative study of two such stem cells in a very systematic way. The study is a follow-up of similar studies previously published [3] with more extensive analytical tools to see the extent of stem cell-mediated repair process in focal ischemia models.
