In brain injury, stem cells induce neuroprotection and neural repair by inflammatory suppression,
causing tissue reconstruction of completely or partially damaged cells and prevent
cell death. [26] On administration, these cells migrate to the injured tissue and initiate host
repair and recovery through direct and indirect cell-cell signaling. [27]The safety of use of bone
marrow derived cells has been well established as they have an autologous origin and do not
result in tumor formation.
