工程自然杀伤细胞可以消除胶质母细胞瘤癌症干细胞

Deleting the TFG-β receptor in NK cells overcame immune suppression and enabled anti-tumor activity in preclinical models. Preclinical research from The University of Texas MD Anderson Cancer Center finds that although glioblastoma stem cells (GSCs) can be targeted by natural killer (NK) cells, they are able to evade immune attack by releasing the TFG-β signaling protein, which blocks NK cell activity. Deleting the TFG-β receptor in NK cells, however, rendered them resistant to this immune suppression and enabled their anti-tumor activity.

使用 MSCs 干细胞从中风中恢复

Stroke is an abrupt interruption of constant blood flow to the brain that causes loss of neurological function, there are 3 types:  a blocked artery ( ischemic   stroke ) or leaking or bursting of a blood vessel ( hemorrhagic   stroke ) and transient ischemic attack ( TIA also known as a mini stroke ). Different factors can lead to a stroke: high blood pressure, high cholesterol, diabetes, and those who smoke. Mesenchymal Stem Cells (MSCs) are not only safe but also one of the only treatment that can improve the patient condition following a stroke. Study show that with Cerebral artery occlusion model the efficacy of interferon‐γ–activated mesenchymal stem cells (aMSCγ) as an acute therapy for stroke.
